In one possible implementation manner, determining the seat where the wearable device is located in the vehicle according to the relative pose data between the wearable device and the plurality of seats may include: and determining the seat corresponding to the minimum relative pose data as the seat where the wearable device is positioned in the vehicle according to the relative pose data between the wearable device and the plurality of seats. Therefore, through the minimum relative pose data, the wearing equipment can identify the seat closest to the pose of the wearing equipment from a plurality of seats in the vehicle as the seat where the wearing equipment is positioned, and the positioning in the vehicle of the wearing equipment is realized.

In one possible implementation manner, the determining that the seat corresponding to the minimum relative pose data is a seat where the wearable device is located in the vehicle may include: and determining the seat corresponding to the minimum variance as the seat where the wearable equipment is positioned in the vehicle according to the variances of the relative pose data corresponding to the plurality of seats. Therefore, the wearing equipment can position the seat with the smallest variance in the vehicle by matching the pose of the wearing equipment with the poses of the seat and solving the variance, so that the in-vehicle positioning of the wearing equipment is realized.

In a possible implementation manner, the wearable device may be a virtual reality device, and after determining, according to the relative pose data between the wearable device and the plurality of seats, the seat in which the wearable device is located in the vehicle, the device interaction method of the present application may further include: and generating a virtual reality picture according to the relative pose data between the wearing equipment and the seat where the wearing equipment is located.

When the vehicle has acceleration in only one direction, the pose changes of the positions of the seats of the vehicle are identical, so that the wearable device cannot realize the in-vehicle positioning of the wearable device according to the seat pose data of a plurality of seats. That is, the condition for the wearable device to successfully perform in-vehicle positioning is that the vehicle has acceleration in different directions. The different directions can be different directions of the same horizontal plane or different directions on two different planes, namely the horizontal plane and the vertical plane, based on the different directions, the wearable device can set a successful positioning condition, so that when the vehicle meets the successful positioning condition, the wearable device can successfully position the inside of the vehicle by utilizing the seat pose of a plurality of seats in the vehicle and the equipment pose data of the wearable device.

Therefore, after the vehicle-mounted equipment identifies the pose of the plurality of seats in the vehicle, the pose of the wearing equipment can be matched with the pose of the plurality of seats in the vehicle, so that the vehicle-mounted equipment can identify the seat where the wearing equipment is located, and the in-vehicle positioning of the wearing equipment is realized.

The methods in the following embodiments may be implemented in the in-vehicle apparatus and the wearable apparatus having the above-described hardware structures.

The technical solution provided by the embodiment of the present application will be specifically described below by taking the above-mentioned wearable device as a VR device as an example.

At present, based on the characteristic that the VR technology can simulate the virtual environment to bring the sense of environmental immersion to people, the VR technology is increasingly required by various industries. Vehicles are also increasingly in demand for VR in vehicles as the most common mobile space in human life. Generally, in-car VR can provide meeting, social, game, video, etc. services to people during riding, so that boring emotion during riding can be relieved, and even motion sickness symptoms can be relieved through the services provided by VR.

It will be appreciated that in building a virtual world, VR devices typically need to recognize their own pose information to calculate pose information for the virtual world character from their own pose information so that the VR device can display the virtual world character in the correct position. However, when a user uses a VR device on a running vehicle, even if the user using the VR device is stationary relative to the vehicle, the posture information of the VR device may change due to movement of the vehicle, which results in deviation in posture recognition of the VR device, and thus, accuracy of building a virtual world by the VR device is affected.

For example, when a user engages in a virtual meeting with a VR device on a traveling vehicle, even if the user is stationary with respect to the vehicle, the turning behavior (or the lane change behavior) of the vehicle may cause the VR device within the vehicle to recognize an angular velocity in a horizontal direction, resulting in the VR device correspondingly adjusting the posture of the virtual world character according to the recognized posture change.

Illustratively, (a) in fig. 3 and (b) in fig. 3 show a changing schematic diagram of a virtual screen displayed by an in-vehicle VR device. As shown in fig. 3 (a) and 3 (b), when a user on a rear seat of a vehicle participates in a virtual conference through VR glasses worn on his head, the user can view the virtual conference screen 300 through the VR glasses, and the virtual conference screen 300 includes a virtual character 301. Wherein the posing appearance of the virtual character 301 can rotate following the rotation of the user's head.

As shown in fig. 3 (a), when the user's head is facing forward, the virtual character 301 displayed on the VR glasses is in an upright posture. As shown in fig. 3 (b), after the user turns his head, the VR glasses worn on his head recognize the angular velocity in the horizontal direction, and the VR glasses adjust the posture of the displayed virtual character 301 to be on the side of his body according to the recognized angular velocity in the horizontal direction. That is, rotation of the user's head causes the virtual character 301 displayed by the VR glasses to also rotate.

However, when the user does not turn the head, i.e., when the user is stationary with respect to the vehicle, turning of the vehicle may also cause the virtual character displayed by the VR glasses to turn. Illustratively, (a) in fig. 4 and (b) in fig. 4 show a changing schematic diagram of a virtual screen displayed by another in-vehicle VR device. As shown in fig. 4 (a) and 4 (b), when a user on a rear seat of a vehicle participates in a virtual conference through VR glasses worn on his head, the user can view the virtual conference screen 400 through the VR glasses, and the virtual conference screen 400 includes a virtual character 401.

As shown in fig. 4 (a), before the vehicle turns, the virtual character 401 displayed by the VR glasses is oriented with the body facing the user. If the vehicle turns at this time, even if the user and the VR glasses worn are stationary with respect to the vehicle, the VR glasses recognize the angular velocity in the horizontal direction, and the VR glasses adjust the posture of the displayed virtual character 401 according to the recognized angular velocity in the horizontal direction. As shown in fig. 4 (b), when the vehicle turns, if the user and the VR glasses worn are still stationary with respect to the vehicle, the posture of the virtual character 401 displayed on the VR glasses changes to the body side facing the user. That is, turning of the vehicle also causes the virtual character 401 displayed by the VR glasses to rotate.

However, in practical applications, if the user and the VR device worn are stationary relative to the vehicle, the virtual world character should also remain stationary, and the virtual world character should not turn due to the turning of the vehicle (i.e., when the VR device in the vehicle recognizes an angular velocity in the horizontal direction, it is necessary to distinguish whether the angular velocity source is a turning of the vehicle or a turning of the user).

Therefore, in view of the above-described problems, in an in-vehicle VR scene, it is necessary for the VR device to acquire relative posture information between the VR device and the vehicle (i.e., posture information of the VR device with respect to the vehicle) to calculate posture information of the virtual world character from the relative posture information of the VR device. Rather than relying solely on the pose information of the VR device itself to calculate the pose information of the virtual world character.

Currently, in order to obtain relative posture information of a VR device, the VR device is usually implemented by providing 4 cameras at four corners of the VR device. Specifically, the VR device can acquire the surrounding environment image in real time through the equipped 4 cameras, so that the VR device can recognize the relative posture information of the VR device according to the front and rear frame image changes. However, this method has high requirements for configuring cameras of VR devices, high cost of 4 cameras, and inaccurate and erroneous recognition problems (such as image change caused by brightness change of ambient light, and misjudgment as posture change of VR devices) exist due to the requirement of image recognition on ambient light. In addition, the image acquisition also involves the problem of user privacy, and the user experience is poor.

In view of the above problems, the embodiment of the application provides a device interaction method, which can identify the relative gesture information of a VR device relative to a specific position in a vehicle only by using a sensor carried by the vehicle and a sensor carried by the VR device, and the accuracy of the identified relative gesture information is higher. The technical scheme provided by the embodiment of the application not only can identify the gesture information of different positions in the vehicle, but also can identify the position of the user using the VR equipment in the vehicle, and can accurately identify the gesture change of the VR equipment relative to the position of the user. Therefore, when a user uses the VR equipment at different positions in the vehicle, the application can accurately acquire the gesture information of the VR equipment relative to different positions in the vehicle, and can also realize the accurate positioning of the VR equipment in the vehicle. Compared with the prior art, the application does not need to additionally increase devices, and has low cost and good privacy.

It can be understood that, because the postures of different positions in the vehicle are different in the running process of the vehicle, when the posture of the virtual world role is constructed, the VR device can accurately calculate the posture information of the virtual world role by utilizing the posture information of the VR device relative to the position of the user, rather than simply calculating by utilizing the posture information of the VR device relative to the vehicle, thereby improving the posture accuracy of the virtual world role of the VR in the vehicle and ensuring the use experience of the VR device.

The device interaction method provided by the embodiment of the application is described below by taking the vehicle-mounted device as a vehicle-mounted communication terminal T-Box as an example and combining the drawings. As shown in fig. 5, the device interaction method may include:

s510, the vehicle-mounted communication terminal acquires vehicle pose data.

In the embodiment of the application, the vehicle pose data can comprise motion data such as the speed, the acceleration, the angular speed, the angular acceleration and the like of the vehicle in the running process of the vehicle, and the data comprise components along all directions of a space. The vehicle pose data may also include data such as geographic coordinate data (e.g., longitude and latitude data of the earth) and displacement during the running process of the vehicle, so as to calculate motion data such as speed, acceleration, angular velocity and angular acceleration of the vehicle according to the data.

In one possible implementation, the vehicle pose data may be acceleration data and angular velocity data of the vehicle during its travel. Alternatively, in the x, y, z three-dimensional coordinate system, the vehicle pose data of the present application may be obtained using three-axis angular velocities ω _x ，ω _y ，ω _z And triaxial acceleration a _x ，a _y ，a _z To represent. The three-axis angular velocity is understood to be the angular velocity of the vehicle about the three x, y, z axes, and the three-axis acceleration is understood to be the acceleration of the vehicle in the three x, y, z axes.

For example, as shown in fig. 6, the motion of the vehicle in the x, y, z three-dimensional coordinate system may include three translational motions including a leftward and rightward translational motion of the vehicle in the x-axis, a forward and backward translational motion in the y-axis, and an upward and downward translational motion in the z-axis. The three rotational movements include a rotational movement of the vehicle about the x-axis (the angle of rotation is also referred to as Pitch angle Pitch), a rotational movement about the y-axis (the angle of rotation is also referred to as Roll angle Roll), and a rotational movement about the z-axis (the angle of rotation is also referred to as Yaw angle Yaw).

It will be appreciated that the movement of the vehicle includes translational movement in each of the x, y, and z axes, with an acceleration, a, in each of the x, y, and z axes _x ，a _y ，a _z . The movement of the vehicle comprising a rotational movement about each of the three axes x, y, z corresponds to an angular velocity, ω, in each of the three axes x, y, z _x ，ω _y ，ω _z . Movement of the vehicle in three dimensions can be resolved into translation and/or movement in the x, y, z axes.Thus, the pose change generated during the running of the vehicle can be controlled by the three-axis angular velocity omega of the vehicle in the x, y and z axes _x ，ω _y ，ω _z And triaxial acceleration a _x ，a _y ，a _z To represent.

Due to the three translational movements and three rotational movements in the x, y, z three-dimensional coordinate system, which are physical, also referred to as six degrees of freedom of the object. Thus, in some embodiments, the vehicle pose data acquired by the in-vehicle communication terminal may also be the degree of freedom data of the vehicle.

Since a sensor (such as an IMU sensor) for periodically detecting a change in the posture of the vehicle is generally installed in the vehicle, the data sensed by the sensor generally includes three-axis angular velocity ω _x ，ω _y ，ω _z And triaxial acceleration a _x ，a _y ，a _z . Therefore, the vehicle pose data in the embodiment of the application can be measured by the sensor. The vehicle-mounted communication terminal can acquire vehicle pose data from the sensor.

Because a sensor for periodically detecting a posture change of the VR device is also typically installed in the VR device, for convenience of understanding and distinction, the sensor for detecting a posture change of the vehicle may be referred to as a first sensor, and the sensor for detecting a posture change of the VR device may be referred to as a second sensor in the embodiments of the present application.

Alternatively, the first sensor may be built in the vehicle-mounted communication terminal, so that the vehicle-mounted communication terminal may directly acquire the vehicle pose data detected by the first sensor.

Alternatively, the first sensor may also be accessed to the vehicle-mounted network as an independent ECU, so that the vehicle-mounted communication terminal may read the vehicle pose data from the vehicle-mounted network. The arrangement mode of the first sensor is not limited in the embodiment of the application. The on-board network may be a CAN, LIN, MOST, flexRay, ethernet or other on-board network. Taking a CAN network as an example, each ECU and vehicle-mounted equipment in the vehicle are connected to a CAN bus to form a vehicle-mounted network of the vehicle, and the vehicle-mounted equipment and the ECU CAN communicate through the CAN bus. The vehicle-mounted equipment CAN read the vehicle pose data detected by the first sensor through the CAN bus.

Alternatively, the vehicle-mounted communication terminal may acquire vehicle pose data at a fixed period, or may acquire vehicle travel data in real time. The fixed period may be set according to actual needs, and the embodiment of the present application is not limited.

S520, the vehicle-mounted communication terminal acquires vehicle running data.

In the embodiment of the application, the vehicle running data may refer to vehicle data in the running process of the vehicle. The vehicle data may include rudder angle of the vehicle, vehicle speed, gear, and the like. Since a vehicle sensor for detecting vehicle travel data is generally provided in a vehicle, the vehicle travel data in the embodiment of the application can be measured by the vehicle sensor. The vehicle sensor may include a wheel speed sensor for measuring a vehicle speed, a rudder angle sensor for measuring a rudder angle of the vehicle, and other sensors for measuring other vehicle data, and the specific type of the vehicle sensor is not limited in the embodiment of the present application.

Alternatively, since a steering wheel on a vehicle is generally interlocked with the front wheels of the vehicle, a user can operate the steering direction of the front wheels by turning the steering wheel, so that the traveling direction of the vehicle can be controlled. Accordingly, the rudder angle of the vehicle may also be referred to as a steering wheel angle, and the vehicle sensor may include a steering wheel angle sensor for measuring the steering wheel angle of the vehicle. Alternatively, the rudder angle of the vehicle may be a vehicle front wheel angle, and the vehicle sensor may also include a front wheel angle sensor for measuring the vehicle front wheel angle.

Alternatively, the vehicle sensor may be accessed to the in-vehicle network as an independent ECU, so that the in-vehicle communication terminal may read the vehicle pose data from the in-vehicle network. Alternatively, the vehicle sensor may be integrated as a component in other devices in the vehicle, so that the vehicle-mounted communication terminal may acquire vehicle pose data from the other devices through the vehicle-mounted network. The arrangement mode of the vehicle sensor is not limited in the embodiment of the application.

Alternatively, the vehicle-mounted communication terminal may acquire the vehicle running data at a fixed period, or may acquire the updated vehicle running data when the vehicle running data changes. The fixed period may be set according to actual needs, and the embodiment of the present application is not limited.

Note that S510 and S520 may be performed simultaneously, or S520 may be performed before S510. The embodiment of the present application does not limit the specific sequence between S510 and S520.

It will be appreciated that if the vehicle turns (or runs) during its travel, the vehicle will experience an acceleration in the horizontal direction. When the vehicle turns, the centrifugal forces of different seats in the vehicle are different, so that the accelerations generated on the different seats in the vehicle are substantially different, which means that the posture changes generated on the different seats in the vehicle cabin are different during the running process of the vehicle. If the VR device directly uses the vehicle gesture to identify the relative gesture information of the VR device, a relatively large deviation in gesture identification of the VR device is easily caused, so that subsequent application of the VR device is affected.

Based on the above, in the embodiment of the application, the vehicle-mounted communication terminal can identify the gesture of the target position in the vehicle, so that the VR device can identify the relative gesture information of the VR device relative to the target position by utilizing the gesture of the target position, thereby enabling the VR device to accurately identify the relative gesture information of the VR device and the target position when the VR device is used by a user in the target position in the vehicle, improving the accuracy of gesture identification of the VR device and ensuring the use experience of the VR device. The target position may be any one or more positions in the vehicle, which may include one or more positions of seats in the cabin, or may include a position other than a seat (such as a position of a passage between seats), and the specific target position is not limited in the embodiment of the present application.

It can be understood that when the target position is the positions of a plurality of seats in the seat cabin, the vehicle-mounted communication terminal can identify the gesture information of the plurality of seats in the vehicle, so that when the VR equipment is used by a user on different seats in the seat cabin of the vehicle, the relative gesture information of the VR equipment and the current seat of the user can be accurately identified, the gesture identification accuracy of the VR equipment is improved, and the use experience of the VR equipment is ensured.

Alternatively, the in-vehicle communication terminal may determine the pose data of the target position in the vehicle by two methods. As an embodiment, the vehicle-mounted communication terminal may determine pose data of the target position in the vehicle according to a preset pose conversion relationship. As shown in fig. 5, the device interaction method may include S530A:

S530A, the vehicle-mounted communication terminal determines pose data of a target position in the vehicle according to the vehicle pose data, the vehicle driving data and a preset pose conversion relation.

The preset pose conversion relationship may refer to a mapping relationship between a pose of the vehicle under different turning degrees and poses of different positions in the vehicle.

Alternatively, when the target position is a seat position in the vehicle, the preset pose conversion relationship may also refer to a mapping relationship between the vehicle poses under different turning degrees and the seat poses of different seats in the vehicle. It is understood that the pose conversion relationship corresponding to the vehicles of different models may be different due to the difference in the number and arrangement of seats in the vehicles of different models.

Optionally, the preset pose conversion relationship may include a turning parameter, a seat parameter in the vehicle, and a mapping relationship. The turning parameter indicates the turning degree of the vehicle, and may be a rudder angle (such as 0 °, 10 °) of the vehicle, a steering wheel angle, or a turning radius for indicating the turning degree. The specific turning parameters are not limited in the embodiments of the present application. The seat parameter in the vehicle may be a seat identifier, such as Post 1, post 2, etc., for indicating a particular seat in the vehicle. The mapping relationship may be a mapping parameter involved in the transition of the vehicle pose to the seat pose.

In one possible implementation, the preset pose conversion relationship may be stored in the form of a conversion table T (Pos), so that the pose conversion relationship may be converted by a conversion rule: seat pose of target seatD _[Pos] Vehicle pose d×t (Pos), seat pose data for each seat in the vehicle is obtained. Wherein the target seat is any seat in the vehicle, and the Pos is a seat identifier of the target seat in the vehicle. Illustratively, the conversion table T (Pos) may be as shown in table 1:

TABLE 1

Wherein k0, k1, …, k11, …, m0, m1, …, m5, … are the triaxial angular velocities ω in the above vehicle pose _x ，ω _y ，ω _z And triaxial acceleration a _x ，a _y ，a _z And the mapping coefficients corresponding to the mapping coefficients respectively. Taking the seat Post 1 in the vehicle as an example, when the rudder angle of the vehicle is 10 °, the triaxial acceleration a of the seat Post 1 can be obtained based on the above-described conversion table T (Pos) _x ' _＝ k6×a _x ，a _y ' _＝ k7×a _y ，a _z ' _＝ k8×a _z And a triaxial angular velocity omega _x '＝k9×ω _x ，ω _y ' _＝ k10×ω _y ，ω _z ' _＝ k11×ω _z 。

Alternatively, the above-described pose conversion relationship may be obtained in advance by performing experiments of various driving scenes on the vehicle. As a way, when a vehicle of a target vehicle type is developed, different turning scenes (such as left lane changing, right lane changing, left turning, right turning, turning around and the like) of the vehicle can be tested in advance to measure the pose changes of the vehicle and the pose changes of each seat in the vehicle under different scenes, and then the conversion relation between the pose of the vehicle of the target vehicle type and the pose of each seat in the vehicle under different turning degrees (different rudder angle angles) can be established according to test results. In the practical application scene, after the vehicle of the target vehicle type acquires the vehicle pose data and the vehicle driving data, the seat pose data of each seat in the vehicle can be quickly identified by inquiring the preset pose conversion relation, so that the calculation time is short and the instantaneity is high.

Similarly, when the target position is a non-seat position in the vehicle, the embodiment of the application can also refer to the principle to pre-establish the conversion relation between the vehicle pose and the pose of the non-seat position in the vehicle under different turning degrees (different rudder angle angles) of the vehicle of the target vehicle type. Correspondingly, the preset pose conversion relation can comprise a turning parameter, a position parameter of a non-seat position and a mapping relation. Therefore, in an actual application scene, even if a user wearing the VR equipment is not in a seat, the vehicle of the target vehicle type can quickly identify pose data of a non-seat position in the vehicle by inquiring the preset pose conversion relation.

In some embodiments, the preset pose conversion relationship may be stored in the vehicle in advance. Alternatively, the preset pose conversion relationship may be preconfigured in the vehicle-mounted communication terminal. Alternatively, the preset pose conversion relationship may be configured in other devices in the vehicle, and obtained by the vehicle-mounted communication terminal from the other devices in the vehicle. In other embodiments, the preset pose conversion relationship may also be stored in the server, and the vehicle-mounted communication terminal requests the server to obtain the pose conversion relationship. The storage location and the acquisition mode of the specific pose conversion relationship are not limited in the embodiment of the application.

As an alternative, in some embodiments, as shown in fig. 5, S530A may be replaced with S530B:

S530B, the vehicle-mounted communication terminal determines pose data of a target position in the vehicle according to the vehicle pose data, the vehicle running data and the position of the first sensor in the vehicle.

As another embodiment, when the vehicle pose data is detected by the first sensor in the vehicle, the vehicle-mounted communication terminal may calculate the pose data of the target position in the vehicle in real time according to the position of the first sensor in the vehicle.

It is understood that the difference between the pose data of the vehicle detected by the first sensor and the pose data of the target position is related not only to the degree of turning of the vehicle but also to the difference between the position of the first sensor in the vehicle and the position of the target position in the vehicle. Therefore, the vehicle-mounted communication terminal can identify the position relation between the first sensor and the target position in the vehicle in the current vehicle turning process according to the vehicle running data and the position of the first sensor in the vehicle, and accordingly the vehicle-mounted communication terminal can correspondingly calculate the pose data of the target position in the vehicle according to the position relation.

Alternatively, when the target position is a seat position in the vehicle, the vehicle-mounted communication terminal may identify a positional relationship between the first sensor and each seat in the vehicle during a current turning of the vehicle according to the vehicle running data and the position of the first sensor in the vehicle, so that the vehicle-mounted communication terminal may correspondingly calculate the seat pose data of each seat in the vehicle according to the positional relationship.

In one possible implementation, the first sensor is mounted at a front axle center position of the vehicle, for example. The vehicle-mounted communication terminal can calculate the seat pose data of each seat in the vehicle in real time according to the turning radius of the position of the first sensor and the turning radius of the position of each seat in the vehicle.

Referring to fig. 7, fig. 7 shows a schematic diagram of a vehicle turning according to an embodiment of the present application. Taking the calculation of the seat Post 4 in the vehicle as an example, as shown in fig. 7, an xOy coordinate system is first constructed with the center position of the rear axle of the vehicle as the origin O (0, 0), and then the positions of the first sensor and each seat in the vehicle can be represented by the coordinate points in the coordinate system.

As shown in fig. 7, a coordinate point P (0, h) in the xOy coordinate system indicates an in-vehicle position where the first sensor is located (i.e., a front axle center position of the vehicle). Wherein h is the longitudinal distance between the position of the first sensor and the center position of the rear wheel axle, and r is the turning radius of the position of the first sensor. The coordinate point O' (I, 0) represents the center of a circle corresponding to the turning radius when the vehicle turns. Wherein I is the turning radius of the center position of the rear wheel axle. The coordinate point P' (x, y) indicates the in-vehicle position where the seat Post 4 is located. r' is the turning radius of the seat Post 4 position. θ is the rudder angle of the vehicle.

Since the vehicle is a rigid body, the angular velocity of each position in the vehicle is the same during the turning of the vehicle, and therefore, the seatAngular velocity ω of position Post 4 _x '＝ω _x ，ω _y ' _＝ ω _y ，ω _z ' _＝ ω _z Which coincides with the angular velocity in the vehicle pose data.

Since the turning of the vehicle is performed on a plane and does not involve a change in altitude (e.g., uphill, downhill, etc.), the angular velocity of the seat Post 4 in the vertical z-axis is constant, a _z ' _＝ a _z 。

For acceleration of the vehicle in the plane, taking acceleration in the horizontal direction on the plane as an example, acceleration of the seat Post 4 in the horizontal direction x-axis is:due to->Thus, the first and second substrates are bonded together, it can thus be deduced that:

due toThus, i=h×cotθ, so that it can be further deduced:

substituting the formula to obtain

From the above formulaAs can be seen from the above, the vehicle-mounted communication terminal can obtain the acceleration a of the seat Post 4 on the x-axis by substituting the coordinates x and y of the position in the vehicle of the seat Post 4, the longitudinal distance h between the first sensor and the center position of the rear axle, and the rudder angle θ of the vehicle into the above formula _x '。

Similarly, the vehicle-mounted communication terminal can obtain the acceleration of the seat Post 4 on the y axis on the plane as follows:

it can be understood that, in the case where the xOy coordinate system is fixed, the longitudinal distance h between the first sensor and the center position of the rear wheel axle and the coordinates x, y of the position in the vehicle of the seat Post 4 are fixed values, and are not changed with the change of the running behavior of the vehicle such as turning, lane changing, straight running, etc., only the rudder angle θ of the vehicle needs to be acquired in real time by the vehicle-mounted communication terminal. Accordingly, the in-vehicle position of the first sensor and the in-vehicle positions of the respective seats may be stored in the vehicle in advance, such as being configured in the in-vehicle communication terminal in advance.

It should be noted that, the corresponding calculation formula can be deduced by referring to the above principle for the acceleration of other seats in the vehicle on the plane. When the vehicle rudder angle is obtained, the vehicle-mounted communication terminal can substitute the vehicle-mounted position of the other seats and the vehicle-mounted position of the first sensor into corresponding formulas to obtain pose data of the other seats. The specific derivation process is not described in detail in the embodiments of the present application. Alternatively, the pose calculation formulas of the respective seats may be configured in advance in the vehicle-mounted communication terminal.

Alternatively, the in-vehicle communication terminal may identify only the seat pose data of a certain seat in the vehicle without identifying the seat pose data of all the seats in the vehicle. For example, the vehicle-mounted communication terminal can only identify the pose of the target seat where the VR device is located, so that unnecessary calculation amount can be reduced, and interaction efficiency can be improved.

Similarly, when the target position is a non-seat position in the vehicle, the embodiment of the application can also refer to the principle to identify the position relation of the first sensor and the non-seat position in the vehicle in the current vehicle turning process, so that the vehicle-mounted communication terminal can correspondingly calculate the pose data of the non-seat position in the vehicle according to the position relation. In this way, even if the user wearing the VR device is not in the seat, the in-vehicle communication terminal can recognize the relative pose data between the VR device and the non-seat position.

It can be understood that in the turning process (or lane changing process) of the vehicle, the vehicle generates an acceleration in the horizontal direction (i.e., the x axis) so that the pose changes of all positions on the vehicle are different, so that the embodiment of the application can obtain the pose data of the target position in the vehicle by inquiring the preset pose conversion relationship, or can obtain the pose data of the target position in the vehicle by calculating the position in the vehicle of the first sensor in real time.

Similarly, if the vehicle generates an acceleration in a direction (i.e., a z-axis) perpendicular to the plane during the running process of the vehicle, and the pose changes of each position on the vehicle are different, for example, the vehicle runs on an uphill road section, a downhill road section or an arched bridge, the embodiment of the application can also pre-establish a pose conversion relationship according to the above principle, so that the pose data of the target position in the vehicle can be obtained by inquiring the preset pose conversion relationship. Or the embodiment of the application can refer to the principle so as to calculate the pose data of the target position in the vehicle in real time through the position in the vehicle of the first sensor. The embodiments of the present application are not limited in this regard.

S540, the vehicle-mounted communication terminal sends pose data of a target position in the vehicle to the VR equipment.

In the embodiment of the application, after the vehicle-mounted communication terminal identifies the pose data of the target position in the vehicle, the pose data of the target position in the vehicle can be sent to the VR equipment through wireless connection or wired connection, so that the VR equipment can realize various applications according to the pose data of the target position in the vehicle.

Alternatively, the vehicle-mounted communication terminal and the VR device may complete transmission through wireless connection established by respective wireless communication modules. The wireless connection may be a communication connection such as bluetooth (including bluetooth low energy, classical bluetooth, etc.), WLAN, NFC, IR, etc., and the embodiment of the present application does not limit the type of wireless connection.

Optionally, the vehicle-mounted communication terminal and the VR device may also complete transmission through respective USB interfaces and a wired connection established by a cable.

Taking a wireless connection as a Wi-Fi connection for example, both the vehicle and VR device may have functionality to conduct Wi-Fi communications. When a user carries a VR device within a vehicle, the VR device may access a Wi-Fi local area network provided by the vehicle. When the VR device is connected to the vehicle Wi-Fi network, a Wi-Fi communication module on the vehicle may establish a Wi-Fi communication connection with a Wi-Fi communication module on the VR device. Optionally, the Wi-Fi communication module on the vehicle may be an independent vehicle-mounted component, or may be integrated as a component in a vehicle-mounted communication terminal or other vehicle-mounted devices.

The establishment of the wireless connection or the wired connection may be performed before S510 and S520, or may be performed after S510 and S520.

Alternatively, when the target location is a seat location within the vehicle, the in-vehicle communication terminal may send pose data for one or more seats to the VR device. In one possible implementation, the in-vehicle communication terminal may send pose data for each seat in the vehicle to the VR device. Alternatively, the vehicle-mounted communication terminal may send the seat pose data of each seat in the vehicle to the VR device in real time, or may send the seat pose data of each seat in the vehicle to the VR device in a fixed period. It will be appreciated that when multiple VR devices or other types of devices access a Wi-Fi local area network provided by the vehicle, the in-vehicle communication terminal may also send the seat pose data for each seat in the vehicle to each device that accesses the same Wi-Fi network.

Optionally, the in-vehicle communication terminal may also send seat pose data for each seat in the vehicle to the VR device upon detecting that the vehicle has acceleration in a horizontal direction (i.e., x-axis). It will be appreciated that the vehicle has acceleration in only the fore-aft direction (i.e., the y-axis) when the vehicle is straight on a flat surface. When the vehicle turns or changes track, the vehicle has acceleration in the horizontal direction (i.e., x-axis) in addition to the front-rear direction (i.e., y-axis), that is, the vehicle has acceleration in both directions of the horizontal plane. Thus, the in-vehicle communication terminal may also send seat pose data for each seat in the vehicle to the VR device upon detecting that the vehicle has acceleration in both directions (i.e., x-axis and y-axis) of the horizontal plane.

It will be appreciated that the specific manner of transmitting the seat pose data of each seat is not limited in the embodiments of the present application. For example, the in-vehicle communication terminal may also send seat pose data for each seat in the vehicle to the VR device upon detecting that the vehicle has acceleration in a vertical direction (i.e., z-axis) or that the vehicle has acceleration in both the y-axis and z-axis.

It can be understood that when the target position is a non-seat position in the vehicle, the possible implementation manners of the seat position are also applicable to the non-seat position, and the embodiments of the present application will not be repeated.

In the embodiment of the application, after the VR device receives the pose data of the target position in the vehicle sent by the vehicle-mounted communication terminal, various applications, such as identifying the seat where the passenger is located or identifying the relative pose of the VR device and the vehicle, can be realized according to the received pose data of the target position.

In one embodiment, when the pose data of the target position identified by the vehicle-mounted communication terminal includes seat pose data of each seat in the vehicle, the VR device may implement in-vehicle positioning of the VR device according to the seat pose data of each seat. As shown in fig. 5, the device interaction method may include S550A:

The S550A, VR device determines the seat in which the VR device is located in the vehicle based on the received seat pose data for each seat.

In the embodiment of the application, after the VR device receives the seat pose data of each seat sent by the vehicle-mounted communication terminal, the relative pose data between the VR device and each seat can be determined according to the received seat pose data of each seat and the device pose data of the VR device, and then the VR device can determine the seat where the VR device is located in the vehicle according to the relative pose data between the VR device and each seat, thereby realizing the in-vehicle position positioning of the VR device. The seat in which the VR device is located in the vehicle may be understood as a seat in which a user wearing the VR device is located in the vehicle. Therefore, the in-vehicle positioning of the VR device can be realized by only utilizing the in-vehicle sensor and the in-vehicle sensor of the VR device, the period for positioning is not required to be additionally increased, and the cost is low.

Optionally, the VR device may match the received seat pose data for each seat with device pose data of the VR device itself to obtain relative pose data between the VR device and each seat. In one possible implementation, the VR device may separately obtain the difference between the seat pose data for each seat and the device pose data for the VR device as the relative pose data between the wearable device and each seat. The VR device may then determine, based on the relative pose data corresponding to each seat, the seat corresponding to the minimum relative pose data as the seat in which the VR device is located in the vehicle. The seat corresponding to the minimum relative pose data may be understood as a seat whose pose data is closest to the pose data of the VR device, which is determined from all seats in the vehicle.

In one possible implementation, the VR device may obtain the variance of the relative pose data corresponding to each seat, so as to determine the seat corresponding to the minimum variance as the seat corresponding to the minimum relative pose data, where the VR device is located in the vehicle. Alternatively, the seat corresponding to the minimum relative pose data may be a seat corresponding to the minimum standard deviation (minimum mean square error), which is not limited in the embodiment of the present application.

It can be appreciated that when the pose data of the target position identified by the vehicle-mounted communication terminal does not include the pose data of each seat in the cabin, the vehicle-mounted communication terminal may also send the pose of a part of seats that can be identified to the VR device, so that the VR device may determine, from the part of seats, a seat closest to the pose of the VR device, approximately as a seat in the vehicle, and thus may approximately locate the position of the VR device in the vehicle.

In the embodiment of the application, the VR device can acquire the own device pose data in real time, and also can acquire the own device pose data in a fixed period. The fixed period may be set according to actual needs, and the embodiment of the present application is not limited. The device pose data may include motion data such as velocity, acceleration, angular velocity, and angular acceleration of the VR device, including components along various directions in space. The device pose data may also include data such as geographic coordinate data (e.g., longitude and latitude data of the earth) and displacement of the VR device, so as to calculate, according to the data, motion data such as a speed, an acceleration, an angular speed, an angular acceleration, and the like of the VR device.

Because the VR device is generally built with a second sensor (such as an IMU sensor) for periodically detecting the posture change of the VR device, in the embodiment of the present application, the VR device may acquire its own device posture data through the built-in second sensor.

In some embodiments, the VR device may perform step 540A upon detecting that the VR device is currently in an automatic positioning mode to enable the VR device to achieve its in-vehicle positioning.

Optionally, the VR device may enter an automatic positioning mode when the VR device satisfies a trigger positioning condition. The trigger positioning condition may include at least one of a VR device not being positioned, a VR device being moved, or a user triggered relocation.

It will be appreciated that the pose changes at each position of the vehicle are not the same because the vehicle turns causing the vehicle to experience one more acceleration in the horizontal direction (i.e., x-axis). If the vehicle is traveling straight, however, the vehicle has only one acceleration in the fore-and-aft direction (i.e., the y-axis), the pose changes of the respective seat positions of the vehicle are virtually identical, and in this case the VR device cannot realize its own in-vehicle positioning according to the seat pose data of the respective seats. That is, the VR device successfully performs in-vehicle positioning if the vehicle has acceleration in different directions of the horizontal plane. Thus, in some embodiments, the VR device may enter an automatic positioning mode when the vehicle satisfies a positioning success condition. The successful positioning condition may include, among other things, acceleration of the vehicle in both directions (i.e., x-axis and y-axis) of the horizontal plane.

Similarly, when the vehicle has one more acceleration in the vertical direction (z axis) and the pose of each position of the vehicle is different (such as the vehicle is ascending and descending), the successful positioning condition may also include that the vehicle has acceleration in the horizontal direction (i.e. x axis) of the plane and in the direction perpendicular to the plane (i.e. y axis). The embodiments of the present application are not limited in this regard.

Alternatively, since the acceleration of each position in the vehicle is different when the vehicle turns, the vehicle goes up and down a slope, the positioning success condition may also include at least one of a turning state, an uphill driving state, or a downhill driving state of the vehicle.

Optionally, the trigger positioning condition and the positioning success condition may also be used together as a determination condition of the automatic positioning mode, i.e. when the VR device satisfies the trigger positioning condition and the vehicle satisfies the positioning success condition, the VR device may enter the automatic positioning mode.

Alternatively, since the position changes of the respective seat positions of the vehicle are substantially identical when the vehicle does not satisfy the positioning success condition, the position recognition of the respective seats of the vehicle is not significant at this time. Therefore, the vehicle-mounted communication terminal can recognize the seat pose of the seat in the vehicle when the vehicle meets the positioning success condition. Or the vehicle-mounted communication terminal can also send the seat pose data of each seat in the vehicle to the VR device when the vehicle meets the positioning success condition.

In some embodiments, the in-vehicle communication terminal may also send only the seat pose data of the target seat to the VR device after locating the target seat in which the VR device is located in the vehicle.

Optionally, after the VR device locates the target seat where the VR device itself is located, the positioning result of the VR device may be sent to the vehicle-mounted communication terminal, so that the vehicle-mounted communication terminal may send only the seat pose data of the target seat to the VR device according to the positioning result of the VR device.

Optionally, the VR device may also send its own device pose data to the vehicle-mounted communication terminal, where the vehicle-mounted communication terminal locates the VR device according to the device pose data of the VR device. Therefore, the vehicle-mounted communication terminal can only send the seat pose data of the target seat to the VR device according to the positioning result of the VR device.

Alternatively, the target seat in which the VR device is located in the vehicle may also be manually specified by the user. It is understood that when the user manual specification result is received by the in-vehicle communication terminal, the in-vehicle communication terminal may transmit only the seat pose data of the target seat to the VR device according to the user manual specification result. When the result of the manual specification by the user is received by the VR device, the VR device may acquire the seat pose data of the target seat from the seat pose data of each seat transmitted by the in-vehicle communication terminal.

As an alternative, when the pose data of the target position identified by the vehicle-mounted communication terminal includes pose data of a target seat in the vehicle, the VR device may implement relative pose identification of the VR device with respect to the target seat according to the pose data of the target seat. The target seat is a seat where the VR device is located in the vehicle. As shown in fig. 5, S550A may be replaced with S550B:

the S550B, VR device determines relative pose data between the VR device and the target seat from the received pose data of the target seat.

As another embodiment, the VR device may determine the relative pose data between the VR device and the target seat according to the received seat pose data of the target seat, so that the relative pose recognition of the VR device relative to the seat in which the VR device is located is not simply implemented, but rather the relative pose recognition of the VR device relative to the vehicle is accurately implemented. Therefore, the posture information of the VR device relative to the seat where the VR device is located can be identified by only using the sensor of the vehicle and the sensor of the VR device, and meanwhile, the accuracy of the identified relative posture information is high.

Alternatively, the VR device may determine relative pose data between the VR device and the target seat based on the received seat pose data of the target seat and the device pose data of the VR device itself. The relative pose data can be used as Relative pose data between VR devices and vehicles for use in implementing various applications. Alternatively, the VR device may use the VR device's own device pose data (ω _vr ，a _vr ) The seat pose data (ω ', a') of the target seat is subtracted to obtain relative pose data between the VR device and the target seat.

In one possible implementation, the VR device may use the relative pose data between the VR device and the target seat for pose representation in the virtual world, improving pose accuracy in the virtual world when the user uses the VR device in the vehicle. For example, the VR device may calculate pose information for the virtual world character from relative pose data between the VR device and the target seat and generate the virtual reality screen. Accurate display of the virtual world roles is achieved.

It can be understood that the VR device of the present application can accurately calculate the posture information of the virtual world character by using the posture information of the VR device relative to the seat where the VR device is located, instead of simply calculating the posture information of the VR device relative to the vehicle, thereby greatly improving the posture accuracy of the virtual world character of the VR in the vehicle and ensuring the use experience of the VR device.

It can be appreciated that, because the VR device can calculate the pose information of the virtual world character according to the relative pose data between the VR device and the seat in which the VR device is located, when the VR device is used by the user on a different seat in the vehicle, the VR device can recognize that the relative pose data changes, so that the pose of the virtual world character displayed by the VR device also changes.

In some embodiments, the relative pose recognition of S550B may be performed after the VR device positioning of S550A described above. That is, the VR device may obtain the seat in which the VR device is located according to S550A, and then the VR device may obtain only the seat pose data of the seat in which the VR device is located from the vehicle-mounted communication terminal, so as to determine the relative pose data between the VR device and the seat in which the VR device is located. Therefore, the VR device can calculate the posture information of the virtual world roles according to the relative posture data between the VR device and the seat where the VR device is located, and generate a virtual reality picture. Accurate display of the virtual world roles is achieved.

In other embodiments, when the target seat in which the VR device is located is not obtained by performing S550A, the VR device may also perform S550B only, i.e., the VR device directly acquires the seat pose data of the target seat from the in-vehicle communication terminal to determine the relative pose data between the VR device and the target seat and use for pose representation in the virtual world.

In some embodiments, the VR device may also perform S550B relative pose recognition when currently in a non-automatic positioning mode. Thus, as shown in fig. 5, before the above S550A and S550B, the device interaction method may further include:

S550, the VR device judges whether the VR device is in an automatic positioning mode currently. If yes, S550A is executed, and if no, S550B is executed.

It can be appreciated that when the VR device is in the automatic positioning mode, the VR device may determine, according to the received seat pose data of each seat, a target seat in which the VR device is located in the vehicle, so as to implement in-vehicle positioning of the VR device. When the VR equipment is in the non-automatic positioning mode, the VR equipment does not need to be positioned in the vehicle, and the relative pose data between the VR equipment and the target seat is determined according to the received seat pose data of the target seat, so that the relative pose recognition of the VR equipment is realized.

In summary, according to the device interaction method provided by the embodiment of the application, not only the posture information of different seats in the vehicle cabin can be identified, but also the seat of the user using the VR device in the vehicle can be identified, and the posture change of the VR device relative to the seat of the user can be accurately identified. Therefore, when a user uses the VR equipment on different seats in the vehicle seat cabin, the application can accurately acquire the posture information of the VR equipment relative to the different seats in the vehicle, and can also realize the accurate positioning of the VR equipment in the vehicle.
