In the process of implementing the present invention, the inventors have found that at least the following problems exist in the prior art: Since the current user can only determine the other users as the users who need to perform subsequent operations by using the text information displayed by the nickname, gender, distance, and the like. The information that can be relied upon is limited and not intuitive enough, so that even if a follow-up operation such as adding a friend is performed, the final result of the addition is not necessarily the result that the user really wants.

The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

Please refer to FIG. 1 , which is a schematic structural diagram of an implementation environment involved in a target operation method according to an embodiment of the present invention. The implementation environment includes a terminal 120 and a server 140. among them: The terminal 120 may be an electronic device including a camera, and the electronic device may be a smart phone, a tablet computer, an e-book reader, an MP3 player (Moving Picture Exper ts Group Audio Layer 111, a motion picture expert compression standard audio layer 3), MP4 (Moving Picture Exper ts Group Audio Layer IV, Motion Picture Expert Compress Standard Audio Level 3) player, laptop portable computer and desktop computer, etc.

The terminal 120 and the server 140 can be connected by a wireless network or a wired network. The server 140 can be a server, or a server cluster consisting of several servers, or a cloud computing service center. Please refer to FIG. 2, which shows a flowchart of a method for a target operation method provided by an embodiment of the present invention. This embodiment is mainly illustrated by applying the target operation method to the implementation environment shown in FIG. 1 , and the target operation method includes:

Step 202: superimposing information of at least one target on the real-time street view image displayed by the terminal, where the display position of the target information is related to the relative geographical position between the target and the terminal; the street view image is divided into two types: a traditional street view image and real-time Street view image. The traditional street view image is a street view image that is pre-collected and saved in the server, and the terminal can call the street view image to display from the server at any time; the real-time street view image refers to the real-time street view image through the built-in camera when the terminal is located in a certain street scene. The image collected. This article mainly deals with the latter, that is, real-time street view imagery.

The target may be any of other users, other terminals, P0I (Point of Interes t, interest point), and a wireless access point where the IP address can identify the location. In this article, we only give examples to other users.

Step 204: detect, during the motion of the terminal, whether information of a target exists in a predetermined display area of the terminal;

Since the display position of the target information is associated with the relative geographic position between the target and the terminal When the terminal is displaced or rotated, the display position of the target information will also change. The user can control the motion of the terminal so that the information of the target is located in a predetermined display area of the terminal, such as the center of the screen, thereby generating a trigger signal.

Step 206: If the detection result is that the information in which one target exists is located in the predetermined display area of the terminal, the operation for the target is triggered.

In summary, the target operation method provided by the embodiment provides that the display position of the information of the target is associated with the relative geographical position between the target and the terminal by superimposing the information of the at least one target on the real-time street view image, and there is a When the information of the target is located in the predetermined display area of the terminal, the operation for the target is triggered; the existing target operation method is solved, and only the displayed text information can be used to determine whether other users are users who need to perform subsequent operations, and the operation is performed. The result may not be the result of the user's actual desired result; the user can obtain the relative geographical position between the target and the terminal more intuitively through the information of the target superimposed on the real-time street view image, thereby more accurately determining whether the target is The effect of the target that needs to perform subsequent actions. In the above step 202, operations such as calculation of positioning and related display positions are required, and these operations can be mainly performed by the terminal or by the server. Referring to FIG. 3A, a flowchart of a method for operating a target according to another embodiment of the present invention is shown. This embodiment is mainly illustrated by applying the target operation method to the implementation environment shown in FIG. 1. The target operation method includes:

Step 301: The terminal acquires a location parameter of the terminal every predetermined time interval.

First, the terminal acquires the location parameter of the terminal. The location parameter of the terminal usually includes the geographic location of the terminal, the orientation information of the camera of the terminal, and the elevation information of the camera, and may also include the motion information of the terminal. Specifically: If the location parameter of the terminal includes the geographic location of the terminal, the terminal acquires its geographic location through an LBS (Location Based Service) positioning technology; the LBS positioning technology includes but is not limited to: GPS (Global Positioning System, global positioning) System) At least one of positioning technology, COO (Cell of Origin) positioning technology, and TDOA (Time Difference of Arrival) positioning technology.

If the location parameter of the terminal includes the orientation information of the camera of the terminal, the terminal acquires the orientation information of the camera of the terminal through the built-in electronic compass sensor;

If the location parameter of the terminal includes the elevation information of the terminal, the terminal acquires the elevation information of the terminal through the built-in gyro sensor;

If the position parameter of the terminal includes the motion information of the terminal, the terminal acquires the motion information of the terminal through the built-in three-axis acceleration sensor and/or the gyro sensor. The three-axis acceleration sensor is used to acquire motion information when the terminal moves, and the gyro sensor is used to obtain motion information when the terminal rotates.

Step 302: The terminal searches for at least one target that meets a predetermined condition according to the location parameter of the terminal, where the predetermined condition includes that the geographic location of the target belongs to a predetermined range indicated by the location parameter of the terminal;

The predetermined range is typically a sectoral region whose apex angle is determined by the geographic location of the terminal, and the angular bisector of the central angle of the sector is determined by the orientation information of the camera of the terminal.

Specifically, this step includes the following four sub-steps:

First, the terminal uses the geographic location of the terminal as an origin, and establishes a polar coordinate system with the orientation of the camera in the terminal as a polar axis;

Referring to FIG. 3B, the geographic location of the terminal in the initial coordinate system is (x0, yO), and the orientation of the camera is as shown by the ray a, and the point identified by (x0, yO) is used as the polar coordinate system. In the origin, the polar coordinate system is established by using the ray a as the polar axis in the polar coordinate system.

Second, the terminal determines the size of a predetermined radius _r in accordance with the elevation angle information of the camera terminal, the size of numerical size of the elevation information of a predetermined radius r being characterized elevation positive correlation; predetermined radius r dynamically according to the elevation angle information of the camera terminal determine. In other words, the larger the elevation angle of the camera of the terminal with respect to the horizontal line, the larger the predetermined radius r; the smaller the elevation angle of the camera of the terminal with respect to the horizontal line, the smaller the predetermined radius r.

Third, the terminal determines the arc of the sector area at a predetermined radius r by a ray at a predetermined angle β and a predetermined angle θ in the polar coordinate system, and determines a sector of the sector by a predetermined radius r to obtain a sector area;

Let the predetermined angle β be the ray b, and the predetermined angle - β is the ray

C uses ray b and ray c to determine both sides of the central angle of the sector. Wherein the size of β is a preset value or a value associated with the horizontal angle of view of the camera of the terminal. For example, if the camera's horizontal viewing angle is 120 degrees, then β is 60 degrees.

Fourth, the terminal searches for a geographical location belonging to at least one target in the sector area; specifically, the fourth step may include the following sub-steps:

1. The terminal acquires the geographical location of the candidate target objects from the server;

The terminal can obtain the geographical location of the candidate several targets from the server. Specifically, the terminal may send its own geographic location to the server, and then after receiving the geographic location, the server selects several targets within a predetermined distance in the vicinity of the geographic location as candidate targets, and then selects the target of the candidate. The location of the location is fed back to the terminal. Generally speaking, the terminal also obtains information of several candidate targets at the same time, so that it can be used for subsequent display.

4 The geographic location of several targets of the candidate acquired by the terminal is the coordinate (x, y) in the initial coordinate system.

2. The terminal converts the geographic locations of the candidate targets into polar coordinates (p, Θ) in the polar coordinate system; The terminal may convert the geographic locations of the plurality of targets acquired from the server into polar coordinates in the polar coordinate system established in the first step. Referring to FIG. 3C in detail, the terminal specifically converts the geographical position (x, y) of the candidate targets in the initial coordinate system into the first coordinate (xl, yl) in the predetermined Cartesian coordinate system according to the first predetermined formula. The origin of the predetermined Cartesian coordinate system is determined by the geographic location (x0, yO) of the terminal, and the X-axis forward direction of the predetermined Cartesian coordinate system is determined by the orientation information of the camera of the terminal, and the first predetermined formula is:

Xl=x-cos a +ys in α - ( xO'cos a +yO's in α ); yl=— x'.s in a +y"Co s α— (—xO's in a +yO''cos α ) , where α is the angle between the X-axis of the Cartesian Cartesian coordinate system and the positive direction of the X-axis of the initial coordinate system in the counterclockwise direction;

Converting the first coordinate (xl, yl) of each target into a second coordinate (ρ, Θ) in the polar coordinate system according to a second predetermined formula, the second predetermined formula being:

ρ =^1 ² +yl ² , Θ =a tan2 ( yl , xl ),

Where a tan2 ( ) represents the arctangent function, the result is expressed in radians and is between -pi and i (excluding -pi ).

3. The terminal searches for at least one target whose geographic location belongs to the sector based on the converted polar coordinates (p, Θ).

Then, the terminal finds that the geographical location belongs to at least one target in the sector based on the converted polar coordinates ( ρ, Θ ) of the candidate respective targets.

4. If the predetermined condition further includes specifying the attribute, searching for the target that meets the specified attribute from the found at least one target;

Preferably, when the terminal searches for at least one target that meets the predetermined condition according to the location parameter of the terminal, the predetermined condition does not necessarily include only the geographical location of the target belongs to a predetermined range indicated by the location parameter of the terminal, and the predetermined condition may further include specifying Attribute, the specified genus Sex includes at least one of gender, age, status, occupation, category, address, and keywords. For example, the current user needs to query other users whose "one is within 1 000 meters" and whose gender is "female" and whose age is between "18-35".

If the predetermined condition further includes specifying the attribute, the terminal further needs to find the target that meets the specified attribute again from at least one of the targets found in sub-step 3.

It should be noted that the predetermined condition may also include other conditions. For example, when the terminal is a mobile phone, the predetermined condition may further include “a user who shakes the mobile phone simultaneously with the current terminal”. These other conditions may vary from one embodiment to another, but do not affect the description of the present invention, and therefore are not described herein.

Step 303: The terminal determines, according to the relative geographic location between each target and the terminal, a display position of the information of each target in the first display dimension of the terminal and a display position on the second display dimension.

Specifically, the terminal determines, according to the polar coordinates (p, Θ) of each target in the polar coordinate system, the display position of each target information on the first display dimension of the terminal and the display on the second display dimension. a position, a display position on the first display dimension corresponds to a polar coordinate angle 目标 of the target, and a display position on the second display dimension corresponds to a polar coordinate distance p of the target;

Typically, the first display dimension is perpendicular to the second display dimension. The first display dimension refers to the horizontal display dimension of the terminal relative to the ground, and the second display dimension refers to the vertical display dimension of the terminal relative to the ground. Take the terminal as a normal vertical attitude as an example:

For each target, the polar coordinate angle 该 of the target is used as a variable, and the display position of the information of the target in the first display dimension is determined X, X=f x ( Θ ), and X is less than or equal to the screen width W of the terminal;

For each target, the polar coordinate distance p of the target is used as a variable, and the display position Y, Y=fx ( p ) of the information of the target in the second display dimension is determined, and Y is less than or equal to the screen degree 终端 of the terminal. Preferably, X = fx ( θ ) = ( ( β - θ ) /2 β ) * W; Y = fx ( ρ ) = ( p / r ) * Η. For example, the polar coordinates of the target are (200 meters, 30 degrees), β is 60 degrees, r is 1000 meters, W=200 pixels, H=400 pixels, then the horizontal display position of the target is X=50 pixels, Y=80 pixels. . It can be seen that the display position of the target information in the first display dimension indicates the actual position of the target relative to the terminal in the current camera view, and the display position of the target information in the second display dimension indicates the target relative position. In the distance of the terminal, the higher the display position in the second display dimension, the farther the target is from the terminal; the lower the display position in the second display dimension, the closer the target is to the terminal.

Step 304: The terminal superimposes the information of the target on the real-time street view image according to the display position on the first display dimension of the terminal and the display position on the second display dimension.

Finally, the terminal superimposes the information of the target on the real-time street view image according to the display position on the first display dimension on the terminal and the display position on the second display dimension, and the display position on the first display dimension is based on the target and the terminal. The relative direction is determined, and the display position in the second display dimension is determined according to the relative distance between the target and the terminal.

For example, the renderings can be seen in Figure 3D. The target information includes at least one of an avatar, a nickname, an IP address, a gender, an age, a status, an occupation, a category, an address, and a keyword. The information of the target displayed in FIG. 3D is exemplified by an avatar, a nickname, and a gender. For example, the information of goal 33 includes a female avatar, nickname "Amy" and gender "female". The information of goal 34 includes a male avatar, nickname "Winter" and gender "male".

Step 305: The terminal detects, in the motion of the terminal, whether information of a target exists in a predetermined display area of the terminal;

Since the display position of the information of the target is related to the relative geographical position between the target and the terminal, when the terminal is displaced or rotated, the display position of the information of the target also changes. The user can control the motion of the terminal so that the information of the target is located in a predetermined display area of the terminal, such as the center of the screen, thereby generating a trigger signal. Referring to FIG. 3E, the center of the screen of the terminal has a predetermined display area 36 having a rounded rectangular shape. When the terminal is rotated or displaced to the left, the display position of the target 33 is shifted to the right; when the terminal is rotated or displaced to the right, the target is The display position of 33 will shift to the left; when the elevation angle of the camera of the terminal with respect to the horizontal line becomes larger, the display position of the target 33 will move downward; when the elevation angle of the camera of the terminal with respect to the horizontal line becomes smaller, the display position of the target 33 will move up. .

When the user wants to perform a subsequent operation on a certain target 33, the user can make the terminal move to control the target 33 to be located in the predetermined display area 36; at this time, the terminal detects whether there is a target information located in the predetermined display area of the terminal. Inside.

Step 306: If the detection result is that the information that exists in one target is located in the predetermined display area of the terminal, the operation for the target is triggered.

If the detection result of the terminal is that the information in which one target exists is located in the predetermined display area of the terminal, the operation for the target is triggered. Since the target is not necessarily the same in different embodiments in different embodiments, the operations for the target may also be different. Specifically, if the target is another user, triggering at least one of a display detailed information operation, a display operation prompt frame operation, a add friend operation, a send information operation, a send scheduled instruction operation, and a mark operation for the target;

For example, if the target is other users in the instant messaging program, and the target information only displays one dot, the terminal can trigger the display detailed information operation for the target; for example, the target is other users in the instant communication program, and the target The information is displayed with an avatar and a nickname, and the terminal can trigger an add friend operation for the target; for example, if the target is another user in the instant communication program, and the target information displays an avatar and a nickname, the terminal can trigger the target Sending a predetermined instruction operation, which may be an instruction to cause a terminal used by the target to emit light, sound, or vibrate; for example, the terminal may also trigger a marking operation for the target, such as a "like" operation or a "comment" operating. These subsequent operations may need to be completed with the server, the details will not be described in detail. Similarly, if the target is another terminal, triggering at least one of a send information operation, a send file operation, a download file operation, and a establish connection operation for the target; if the target is a P0I point, triggering for the target Displaying a detailed information operation or a navigation operation; if the target is a wireless access point, triggering an operation of accessing the wireless network to which the target belongs.

In summary, the target operation method provided by the embodiment provides that the display position of the information of the target is associated with the relative geographical position between the target and the terminal by superimposing the information of the at least one target on the real-time street view image, and there is a When the information of the target is located in the predetermined display area of the terminal, the operation for the target is triggered; the existing target operation method is solved, and only the displayed text information can be used to determine whether other users are users who need to perform subsequent operations, and the operation is performed. The result may not be the result of the user's actual desired result; the user can obtain the relative geographical position between the target and the terminal more intuitively through the information of the target superimposed on the real-time street view image, thereby more accurately determining whether the target is The effect of the target that needs to perform subsequent actions.

In addition, the following operations are triggered by detecting whether a target information is located in a predetermined display area of the terminal during the motion of the terminal, so that the user can perform the triggering of the subsequent operation by the one-handed handheld terminal, and the whole operation process is simple and efficient. .

However, it should be noted that the display position of the information of the target changes according to the motion change of the terminal, and may be implemented by other possible methods, such as the terminal collecting the motion information of the terminal, and then directly adjusting the information of the target according to the motion information. The display position, in other words, the terminal detects that it has shifted to the left by 1 cm, and then shifts the display position of the target information directly to the right by 1 cm. In another implementation, the display position of the information of the target may be kept still after step 304, but the predetermined display area 36 is changed following the change of the motion of the terminal, and steps 305 and 306 can also be implemented. This article does not specifically limit this. In the above embodiment, only the operation work in the target operation method is mainly completed by the terminal. An example of the line. Since the computing power of the terminal is uneven, in order to alleviate the requirement of the computing power of the terminal when the target operating method is applied to the terminal, the computing operation in the target operating method may be mainly performed by the server. details as follows:

Please refer to FIG. 4, which shows a flowchart of a method for a target operation method according to still another embodiment of the present invention. This embodiment is mainly illustrated by using the target operation method for the implementation environment shown in FIG. 1. The target operation method includes:

Step 401: The terminal sends the location parameter of the terminal to the server every predetermined time interval. First, the terminal acquires its own location parameter every predetermined time interval. The location parameter of the terminal usually includes the geographic location of the terminal, the orientation information of the camera of the terminal, and the camera. The elevation information of the terminal may also include the motion information of the terminal. Specifically:

If the location parameter of the terminal includes the geographic location of the terminal, the terminal acquires its geographic location through an LBS (Location Based Service) positioning technology; the LBS positioning technology includes but is not limited to: GPS (Globa l Pos) It ioning Sys tem, at least one of positioning technology, COO (Cell ll of Or ig in) positioning technology, TDOA (Time Difference of Arr iva l) positioning technology.

Then, the terminal sends its own location parameters obtained to the server each time. Correspondingly, The server receives the location parameter of the terminal transmitted by the terminal every predetermined time interval.

Step 402: The server searches for at least one target that meets a predetermined condition according to the location parameter of the terminal, where the predetermined condition includes that the geographic location of the target belongs to a predetermined range indicated by the location parameter of the terminal;

Specifically, this step includes the following four sub-steps:

First, the server uses the geographic location of the terminal as the origin, and establishes a polar coordinate system with the orientation of the camera in the terminal as a polar axis;

Referring to FIG. 3B, the geographic location of the terminal in the initial coordinate system is (x0, yO), and the orientation of the camera is as shown by the ray a, and the point identified by (x0, yO) is used as the origin in the polar coordinate system. The polar coordinate system is established with the ray a as the polar axis in the polar coordinate system.

Second, the server determines the size of the predetermined radius r according to the elevation information of the camera in the terminal, and the magnitude of the predetermined radius r is positively correlated with the magnitude of the elevation angle represented by the elevation information;

The predetermined radius r is dynamically determined based on the elevation angle information of the camera of the terminal. In other words, the larger the elevation angle of the camera of the terminal with respect to the horizontal line, the larger the predetermined radius r; the smaller the elevation angle of the camera head with respect to the horizontal line, the smaller the predetermined radius r.

Third, the server determines the arc angles of a sector area at a predetermined radius r by a ray at a predetermined angle β and a ray at a predetermined angle β in a polar coordinate system, and determines an arc of the sector area at a predetermined radius r to obtain a sector area;

Let the ray where the predetermined angle β is located be the ray b, and the ray where the predetermined angle θ is located is the ray C, and the ray b and the ray c determine the two sides of the central angle of the sector. Wherein, the size of β is a preset value or a value associated with a horizontal viewing angle of a camera of the terminal. For example, camera The horizontal viewing angle is 120 degrees, and β is 60 degrees.

Fourth, the server searches for a geographical location belonging to at least one target in the sector area; specifically, the fourth step may include the following sub-steps:

1. The server obtains the geographical locations of the candidate targets;

The server obtains the geographic locations of the candidate's several targets. Specifically, the server may use several targets within a predetermined distance near the geographic location of the terminal as candidates for several targets. In general, the server also obtains information about several candidate targets for later use.

It is assumed that the geographic locations of several targets of the candidate obtained by the server are the coordinates (X, y) in the initial coordinate system.

2. The server converts the geographic locations of the candidate targets into polar coordinates (P, Θ) in the polar coordinate system;

The server can convert the geographic locations of the candidate targets into polar coordinates in the polar coordinate system established in the first step. Referring to Figure 3C, specifically:

The server converts the geographical position (x, y) of the candidate targets in the initial coordinate system into a first coordinate (xl, yl) in a predetermined Cartesian coordinate system according to a first predetermined formula, and the origin of the predetermined Cartesian coordinate system is The geographical position (x0, yO) of the terminal determines that the X-axis forward direction of the predetermined Cartesian coordinate system is determined by the orientation information of the camera of the terminal, and the first predetermined formula is: xl=x cos a +y's in α - ( xO cos a +yO s in α ); yl=— x'.s in a +y'cos α— (— xO's in a +yO'cos α ), where α is the positive X-axis of the Cartesian Cartesian coordinate system Counterclockwise pointing to the angle between the positive X-axis of the initial coordinate system;

Converting the first coordinate (xl, yl) of each target into a second coordinate (ρ, Θ) in the polar coordinate system according to a second predetermined formula, the second predetermined formula being: p

, Θ =a tan2 ( yl , xl ),

3. The server searches for at least one target whose geographic location belongs to the sector based on the converted polar coordinates (p, Θ).

Then, the server searches for at least one target in the sector based on the converted polar coordinates (p, Θ) of the candidate targets.

Preferably, when the server searches for at least one target that meets the predetermined condition according to the location parameter of the terminal, the predetermined condition does not necessarily include only the geographical location of the target belongs to a predetermined range indicated by the location parameter of the terminal, and the predetermined condition may further include specifying An attribute that includes at least one of gender, age, status, occupation, category, address, and keyword. For example, the current user needs to query other users who are "within 1000 meters" and whose gender is "female" and whose age is between "18-35".

If the predetermined condition further includes specifying an attribute, the server also needs to find the target that meets the specified attribute again from at least one of the targets found in sub-step 3.

Step 403: The server determines, according to the polar coordinates (p, Θ) of each target in the polar coordinate system, the display position of the information of each target in the first display dimension of the terminal and the display position in the second display dimension. ;

Specifically, the server coordinates the polar coordinates of each target in the polar coordinate system. (P, θ) determining a display position of the information of each target in the first display dimension of the terminal and a display position on the second display dimension, and the display position on the first display dimension corresponds to the polar coordinate angle 目标 of the target, The display position on the second display dimension corresponds to the polar coordinate distance ρ of the target;

For each target, the polar coordinate angle 该 of the target is used as a variable, and the display position of the information of the target in the first display dimension is determined X, X=fx ( Θ ), and X is less than or equal to the screen width W of the terminal;

For each target, the polar coordinate distance p of the target is used as a variable, and the display position Y, Y=fx ( p ) of the information of the target in the second display dimension is determined, and Y is less than or equal to the screen width of the terminal. .

Preferably, X = fx ( Θ ) = ( ( β - θ ) / 2 β ) * W; Y = fx ( p ) = ( p / r ) * H. For example, the polar coordinates of the target are (200 meters, 30 degrees), β is 60 degrees, r is 1 000 meters, W = 200 pixels, H = 400 pixels, then the horizontal display position of the target is X = 50 pixels, Y = 80 Pixel. It can be seen that the display position of the target information in the first display dimension indicates the actual position of the target relative to the terminal in the current camera view, and the display position of the target information in the second display dimension indicates the target relative position. In the distance of the terminal, the higher the display position in the second display dimension, the farther the target is from the terminal; the lower the display position in the second display dimension, the closer the target is to the terminal.

Step 404: The server sends, to the terminal, a display position of the at least one target on the first display dimension, and a display position and information on the second display dimension.

Correspondingly, the terminal receives the display position of the at least one target fed back by the server in the first display dimension, the display position and the information in the second display dimension. Where the first display dimension The display position on the top corresponds to the polar coordinate angle 目标 of the target, and the display position on the second display dimension corresponds to the polar coordinate of the target.

Step 405: The terminal superimposes the information of the target on the real-time street view image according to the display position on the first display dimension of the terminal and the display position on the second display dimension.

The display position on the first display dimension is determined according to the relative direction between the target and the terminal; the display position on the second display dimension is determined according to the relative distance between the target and the terminal. The effect diagram can be seen in Figure 3D. The target information includes at least one of an avatar, a nickname, an IP address, a gender, an age, a status, an occupation, a category, an address, and a keyword. The information shown in Figure 3D for Target 33 and Target 34 is exemplified by avatar, nickname and gender.

Step 406: The terminal detects, in the motion of the terminal, whether information of a target exists in a predetermined display area of the terminal;

Since the display position of the information of the target is related to the relative geographical position between the target and the terminal, when the terminal is displaced or rotated, the display position of the information of the target also changes. The user can control the motion of the terminal so that the information of the target is located in a predetermined display area of the terminal, such as the center of the screen, thereby generating a trigger signal.

Referring to FIG. 3E, the center of the screen of the terminal has a predetermined display area 36 having a rounded rectangular shape. When the terminal is rotated or displaced to the left, the display position of the target 33 is shifted to the right; when the terminal is rotated or displaced to the right, the target is The display position of 33 will shift to the left; when the elevation angle of the camera of the terminal with respect to the horizontal line becomes larger, the display position of the target 33 will move downward; when the elevation angle of the camera of the terminal with respect to the horizontal line becomes smaller, the display position of the target 33 will move up. .

Step 407: If the detection result is that the information that exists in one target is located in the predetermined display area of the terminal, the operation for the target is triggered. If the detection result of the terminal is that the information in which one target exists is located in the predetermined display area of the terminal, the operation for the target is triggered. Since the target is not necessarily the same in different embodiments in different embodiments, the operations for the target may also be different. Specifically, if the target is another user, triggering at least one of a display detailed information operation, a display operation prompt frame operation, a add friend operation, a send information operation, a send predetermined instruction operation, and a mark operation for the target;

For example, if the target is other users in the instant messaging program, and the target information only displays one dot, the terminal can trigger the display detailed information operation for the target; for example, the target is other users in the instant communication program, and the target The information is displayed with an avatar and a nickname, and the terminal can trigger an add friend operation for the target; for example, if the target is another user in the instant communication program, and the target information displays an avatar and a nickname, the terminal can trigger the target Sending a predetermined instruction operation, which may be an instruction to cause a terminal used by the target to emit light, sound, or vibrate; for example, the terminal may also trigger a marking operation for the target, such as a "like" operation or a "comment" operating. These subsequent operations may need to be done interactively with the server, and details are not described here.

Similarly, if the target is another terminal, triggering at least one of a send information operation, a send file operation, a download file operation, and a establish connection operation for the target; if the target is a P0I point, triggering for the target Displaying a detailed information operation or a navigation operation; if the target is a wireless access point, triggering an operation of accessing the wireless network to which the target belongs.

In summary, the target operation method provided by the embodiment provides that the display position of the information of the target is associated with the relative geographical position between the target and the terminal by superimposing the information of the at least one target on the real-time street view image, and there is a When the information of the target is located in the predetermined display area of the terminal, the operation for the target is triggered; the existing target operation method is solved, and only the displayed text information can be used to determine whether other users are users who need to perform subsequent operations, and the operation is performed. The result may not be the result of the user's true hope; the user can pass The information of the target displayed on the real-time street view image is superimposed to more intuitively know the relative geographical position between the target and the terminal, thereby more accurately determining whether the target is an effect of a target that needs to perform subsequent operations.

However, it should be noted that the display position of the information of the target changes according to the motion change of the terminal, and may be implemented by other possible methods, such as the terminal collecting the motion information of the terminal, and then directly adjusting the information of the target according to the motion information. The display position, in other words, the terminal detects that it has shifted to the left by 1 cm, and then shifts the display position of the target information directly to the right by 1 cm. In another implementation, the display position of the information of the target may be kept still after step 405, but the predetermined display area 36 changes in accordance with the motion change of the terminal, and step 406 and step 407 can also be implemented. This article does not specifically limit this. The following is an embodiment of the device of the present invention.
