The technical means shown in the present application will be described in detail below with reference to specific examples. It should be noted that the following embodiments may exist alone or in combination with each other, and description of the same or similar contents is not repeated in different embodiments.
Fig. 2 is a schematic flowchart of an object detection method according to an embodiment of the present application. Referring to fig. 2, the object detection method includes:
s201, receiving at least one object detection information sent by at least one detection device.
The execution subject of the embodiment of the application is an object detection device. The object detection device may be an independent electronic device, or may be integrated into other devices, such as some electronic devices in a home scene. Alternatively, the object detection apparatus may be implemented by software, or may be implemented by a combination of software and hardware.
The object detection device may be in communicative connection with each detection apparatus. The object detection device can be in communication connection with each detection device through Wireless connection modes such as Bluetooth and a mobile hotspot (Wi-Fi). After the object detection device establishes wireless communication connection with the detection equipment, the detection equipment is in an on-network state when the detection equipment is not powered off.
In a home scene, a plurality of detection devices are usually provided, and the detection devices can be arranged at different positions in a room so as to detect objects in more areas in the room. The detection devices may include smart appliances and other smart devices.
The detection device may comprise an intelligent appliance, and the intelligent appliance may comprise at least one of: the intelligent cleaning system comprises a television, a washing machine, a refrigerator, an air conditioner, a range hood, an integrated stove, an induction lamp, an intelligent socket and a cleaning robot. Intelligent appliances are usually deployed in different indoor areas according to their specific functions. For example, a television is generally installed in a living room or a bedroom, a washing machine is generally installed in a kitchen or a bathroom or a balcony, a refrigerator is generally installed in a kitchen or a dining room, and a range hood and an integrated kitchen are generally installed in the kitchen.
According to the actual needs of the user, when the detection area of the intelligent household appliance cannot meet the requirements of the customer, the user can also lay other intelligent equipment capable of realizing the detection function in the uncovered area of the intelligent household appliance according to the actual needs, and optionally, the other intelligent equipment is low-power consumption intelligent detection equipment.
The detection device may have one or more sensing modules by which the detection device detects objects within its detection area. The sensing module may include an infrared sensor and/or a microwave sensor. When the detection equipment is an intelligent household appliance, the sensing module can be used for sensing a human body so as to be beneficial to realizing a wake-up function or a sensing control function and the like. Optionally, at least one of the sensing modules of the detecting devices in the home scene includes an infrared sensor, so as to determine whether the detected object is an organism according to a thermal radiation field detected by the infrared sensor. Optionally, the present embodiment takes the detected object as an example of a biological object.
When a plurality of induction modules are arranged in a household scene, the detection areas of different induction modules can have overlapping areas, and when the plurality of induction modules detect an object in the overlapping areas, the plurality of induction modules can jointly send corresponding object detection information to the object detection equipment, so that the object detection equipment can accurately determine the position of the object.
Before performing step S201, the security mode initiation may be triggered by a user or automatically triggered by a device in a home scenario. When the user triggers and starts the security mode, the user can control the terminal device to send a command for starting the security mode to the object detection device and/or the detection device so as to trigger the detection device and the object detection device of each on-line network to execute corresponding operations. When the security mode is automatically triggered and started, the device in the home scene may trigger and start the security mode according to the closing action of the door, or trigger and start the security mode when the device in the home scene determines that each intelligent household appliance is in a shutdown state or a standby state.
In step S201, the object detection information received by the object detection apparatus may be generated when the sensing module of the detection device detects in real time in the detection area, or may be generated when the sensing module of the detection device detects in the detection area at intervals of a preset time period. Alternatively, the sensing module of the detection apparatus may detect in its detection area at intervals of a preset time period, and when it is determined that the sensing module of the detection apparatus detects an object in its detection range, the sensing module of the detection apparatus may detect in its detection area in real time. In order to reduce the data processing amount of the object detection device, alternatively, the detection apparatus may generate and transmit object detection information to the object detection device when an object is detected in a corresponding detection area.
The object detection information received by the object detection apparatus may include at least one of the following information: at least one detection time, an object position corresponding to each detection time and a device identification. The object orientation is used for representing the position of the object in the detection range of the corresponding detection device, and may include an angle and a distance between the object and the corresponding detection device, where the distance in the object orientation is a distance between a reference line of the detection device and the detected object, and the angle in the object orientation is an angle between the reference line of the detection device and the detected object. The reference point and the reference line of the detection device are preset. The device identifier is used for searching indoor position information of the corresponding detection device, so that the specific indoor position of the detected object can be determined conveniently, and the moving track of the detected object can be determined accurately conveniently.
S202, determining an object detection result corresponding to the home scene according to at least one object detection information, wherein the object detection result comprises at least one of the following: the number of objects included in the home scene or the movement trajectory of the objects in the home scene.
Optionally, the object detection device performs data processing on the received one or more object detection information, and generates an object detection result required by the user according to the data processing result and the user requirement. The user can preset the required object detection result according to the actual requirement.
For example, if the number of detection objects is set in advance by the user, the object detection device determines the number of objects included in the home scene according to the data processing result. The object detection device can send the number of the objects to the terminal equipment, so that the terminal equipment judges whether corresponding prompt needs to be carried out. The object detection device can also generate corresponding prompt information to be sent to the terminal equipment when the object number is determined to be required to prompt. In addition, if the user needs, the object position can be sent to the terminal equipment, and the user can further know the indoor condition of the object.
If the user presets a detection moving track, the object detection device determines the moving track of the object in the home scene according to the data processing result. The object detection device can send the moving track of the object to the terminal equipment, and the terminal equipment displays the moving track of the object, so that a user can know the moving route of the object intuitively. The object detection means may also transmit the detected number of objects to the terminal device together with the movement trajectory.
The object detection method provided by the embodiment of the application determines the number of objects in the home scene or the movement track of the objects in the home scene according to the received object detection information by receiving the object detection information of the detection equipment in the home scene, so that the detection of indoor moving organisms can be realized by utilizing the existing detection equipment in the home scene of a user, such as indoor intelligent household appliances, the additional increase of door magnets is not needed, the operations of withdrawing defenses, replacing batteries and the like in the use process of the existing door magnets are avoided, the convenience in the use process of the user is improved, the user experience is improved, and the indoor privacy of the user is protected; in addition, the embodiment of the application can also provide the moving track of the object in the home scene for the user, and meets more requirements of the user.
The following describes an implementation of object detection with reference to fig. 3. Fig. 3 is a schematic flowchart of another object detection method according to an embodiment of the present application. Referring to fig. 3, the object detection method includes:
s301, receiving at least one object detection information sent by at least one detection device.
It should be noted that, the execution process of step S301 may refer to the execution process of step S201, and details are not described here.
S302, determining a safety mode corresponding to a home scene, wherein the safety mode is an object detection mode or a track detection mode.
To improve the convenience of user operation, optionally, the security mode of the home scenario comprises: an object detection mode and a trajectory detection mode. The user can select a home scene to be in an object detection mode or a track detection mode according to actual needs. For example, when the user leaves the room and determines that there is no other living body in the room, the user can select the object detection mode to be turned on to prevent unauthorized entry into the room. For another example, when the user leaves the room, there is pet activity in the room, or there is activity of other people in the room, such as children or housekeeping personnel, the user may select to turn on the trajectory detection mode; after indoor personnel leave the room, the user can also switch to the object detection mode through the terminal equipment. Of course, in other examples, other security modes such as a location detection mode may be added according to user requirements.
S303, if the safety mode is the object detection mode, determining an object detection result according to at least one object detection information, wherein the object detection result comprises the number of objects; the object detection information comprises at least one detection time and an object position corresponding to each detection time, and the object position comprises an angle and a distance of an object relative to corresponding detection equipment.
That is, when it is determined that the current security mode is the object detection mode, the object detection apparatus determines the number of objects included in the home scene according to the received object detection information.
Alternatively, the number of objects may be determined according to the following possible implementation. Determining an object position corresponding to the detection time according to the object position corresponding to the detection time aiming at any detection time in any object detection information; determining the number of object positions corresponding to each detection moment; determining target detection time in at least one detection time according to the number of the object positions corresponding to each detection time, wherein the number of the object positions corresponding to the target detection time is the largest; and determining the number of the object positions corresponding to the target detection time as the number of the objects.
When the object detection information includes one detection time and the corresponding object bearing, the number of objects can be determined according to the number of object bearings corresponding to the detection time.
When the object detection information includes a plurality of detection times and corresponding object orientations, the maximum value of the number of object positions in the plurality of detection times may be set as the number of objects. Specifically, the object orientations corresponding to the detection times in the object detection information can be respectively determined, and then the object positions corresponding to the detection times can be determined according to the object orientations and the indoor position information of the corresponding detection equipment. Counting the number of object positions corresponding to each detection moment; because the objects can only be located at one specific position in the room at the same time, the number of the object positions corresponding to each detection time can reflect the number of the objects at the corresponding detection time. Comparing the number of the object positions suitable for each detection to obtain the maximum value of the number of the object positions, and taking the maximum value of the number of the object positions as the object number; for convenience of description, the detection time at the maximum value is taken as the target detection time, and the target detection time may be one detection time or a plurality of detection times.
When determining the position of the object corresponding to the detection time according to the position of the object corresponding to the detection time, the following method may be specifically adopted. Acquiring detection equipment corresponding to the detection time and the position of the detection equipment corresponding to the detection time; and determining the position of the object corresponding to the detection time according to the position of the object corresponding to the detection time and the position of the detection equipment corresponding to the detection time.
In other words, the indoor position and the detection area of the detection device matched with the device identifier, which are stored in advance, can be obtained according to the device identifier in the object detection information, and the indoor position, that is, the object position, of the object at the corresponding detection time can be determined according to the detected direction of the object in the detection area and the indoor positions of the detection devices.
The indoor layout information of the user needs to be acquired in advance, and the position information and the detection range of the detection device in the room need to be acquired. The indoor layout information may be determined according to information such as a user-induced floor plan, or may be manually input by a user, and the indoor layout information of the user may be as shown in fig. 4. The area enclosed by the dashed curve segment in fig. 4 is the detection area of the corresponding detection device.
The indoor position information of the detection device can be obtained through manual input by a user or through a positioning module of the detection device, and after the indoor position information of the detection device is determined, the detection range can be determined according to information such as the model of a sensing module of the detection device. As shown in FIG. 5, let N detection settings be provided in a home scene, where N (0 < N ≦ N) is a detection device located indoors at (x) n ，y n ) The detection range function of the detection device is F n (x, y), the detection range function of the detection device can be searched according to the basic information of the device.
S304, if the number of the objects is larger than or equal to a first threshold value, first prompt information is sent to the terminal equipment; the first prompt message comprises the number of objects, and the first threshold is preset by a user.
And comparing the determined number of the objects with a first threshold value, and generating first prompt information and sending the first prompt information to one or more terminal devices when the number of the objects reaches or exceeds the first threshold value. The first threshold value is set or updated by the user according to actual needs. The first prompt information is used for triggering the corresponding terminal equipment to send out sound prompt and/or visual prompt. The terminal device may include an intelligent mobile terminal such as a mobile phone, a tablet computer, a notebook, a vehicle-mounted computer, and the like. The terminal device may further comprise at least one device in a home scenario.
The user can preset the terminal equipment for receiving the first prompt message according to actual needs. In some implementations, the object detection apparatus is configured to send the first prompt message to each selected terminal device, where the at least one terminal device is configured to receive the first prompt message in the object detection mode. For example, the user selects that the terminal device receiving the first prompt message is a mobile phone and an induction lamp in the object detection mode; when the mobile phone receives the first prompt message, the mobile phone can send out a sound prompt or a visual prompt according to the first prompt message; when the induction lamp receives the first prompt message, the induction lamp can be lightened or flickered.
In other implementation manners, the user may preset a priority of the terminal device that receives the first prompt message, and the object detection device may send the first prompt message in sequence according to the preset priority, so as to ensure that the user knows the detection result in time. For example, if the priority set by the user is a mobile phone or a notebook, the object detection device preferentially sends the first prompt information to the mobile phone, and if the object detection device receives the viewed information fed back by the mobile phone, the object detection device determines that the user is prompted; and if the object detection device does not receive the information fed back by the mobile phone within the preset time period, sending first prompt information to the notebook.
For example, if there is no living body in the room after the user leaves the room, the user sets the first threshold to 1 in advance, and the terminal device for receiving the first prompt information is set as a mobile phone in advance, and the user sets the security mode as the object detection module. When the object detection device determines that the number of the objects is equal to or greater than 1 according to the received object detection information, the object detection device generates first prompt information and sends the first prompt information to the mobile phone, so that the mobile phone rings or flashes a prompt lamp according to the first prompt information. If the user leaves the room and then still has a pet, the user sets the first threshold value to be 2 in advance, and when the object detection device determines that the number of the objects is equal to or larger than 2 according to the received object detection information, the object detection device generates first prompt information and sends the first prompt information to the mobile phone, so that the mobile phone rings or flickers a prompt lamp according to the first prompt information.
In the example, the existing detection equipment in the user home scene can be used for detecting the indoor mobile organism, the purpose of anti-theft early warning is achieved, convenience in the use process of a user is improved, user experience is improved, and indoor privacy of the user is protected.
S305, if the safety mode is the track detection mode, determining an object detection result according to at least one object detection information, wherein the object detection result comprises a moving track; the object detection information comprises at least one detection time and an object position corresponding to each detection time, and the object position comprises the angle and the distance of the object relative to the corresponding detection equipment.
That is, when it is determined that the current security mode is the trajectory detection mode, the object detection device determines the movement trajectory of the object in the home scene according to the received object detection information.
Alternatively, the number of objects may be determined according to a possible implementation as follows. Determining an object position corresponding to the detection time according to the object position corresponding to the detection time aiming at any detection time in any object detection information; and splicing the object positions corresponding to the at least one detection time according to the sequence of the at least one detection time to obtain a movement track. The implementation process of determining the position of the object may refer to the related description of step S303, and is not described herein again.
When the object detection information includes the object orientations at a plurality of detection times, the object positions corresponding to the plurality of detection times can be spliced according to the time sequence to obtain the moving track of the object. When the object detection information is multiple, the corresponding object positions in each object detection information can be spliced according to the time sequence to obtain the moving track of the object.
S306, sending the moving track to the terminal equipment.
The terminal device for receiving the movement trajectory has a display unit. And the display unit of the terminal equipment is used for correspondingly displaying the moving track. When a plurality of objects are detected and the movement tracks of the plurality of objects are obtained, the terminal device can display the movement tracks of different objects differently through different line types or different colors and the like. The user can select to view the moving track of a part of objects in the plurality of objects through the terminal equipment.
It can be understood that: the terminal device for receiving the movement track and the terminal device for receiving the first prompt message may be at least partially the same, and the terminal device for receiving the movement track and the terminal device for receiving the first prompt message may be different.
For example, if the user selects the track detection mode, the user sets the terminal device for receiving the movement track as a mobile phone in advance, and when the user leaves the room, the housekeeping staff cleans the room, and then the housekeeping staff can be the object of detection; after the object detection device determines the movement track of the object according to the received object detection information, the movement track is sent to the mobile phone, and a user can check the movement track of the housekeeping personnel through the mobile phone to further determine the cleaning area of the housekeeping personnel. If a pet moves indoors while the user leaves the room, the pet can be a detected object; after the object detection device determines the movement track of the object according to the received object detection information, the movement track is sent to the mobile phone, and a user can check the activity track of the pet through the mobile phone.
In the example, the detection of the indoor mobile organism can be realized by utilizing the existing detection equipment in the user home scene, so that more detection requirements of the user are met, the user experience is favorably improved, and the indoor privacy of the user is favorably protected.
