With continued reference to FIG. 2, a flow 200 of one embodiment of a method for generating location information in accordance with the present application is shown. The method for generating location information includes the steps of:
Step 201, receiving the target image sent by the mobile terminal.
In the present embodiment, the execution subject (e.g., the server shown in fig. 1) of the method for generating location information may receive the target image from the mobile terminal (e.g., the terminal device shown in fig. 1) through a wired connection manner or a wireless connection manner. The target image may be an image obtained by shooting the target point by the moving end. The target point may be a point whose position information is to be determined. Specifically, the target point may be, for example, a point on the ground, a point on a building, a point on natural landscape, or the like.
Here, the moving terminal may obtain the target image in various ways. Specifically, as an example, when the mobile terminal is in a moving state, the execution subject may continuously obtain an image captured by the mobile terminal for a technician to observe, and when the technician observes that a target point is included in the captured image, the execution subject may be used to indicate that the mobile terminal has obtained a target image including the target point; or, the mobile terminal may move to an area for shooting the target point in advance, and then shoot the target point to obtain the target image.
The images (including the target image) captured by the moving end may be images of various shapes (e.g., a circle, a rectangle, a square, etc.) having a center. In addition, the moving direction of the moving end is perpendicular to the shooting direction in the process of shooting the target point.
Step 202, identifying the target image to determine whether the distance between the display position of the target point in the target image and the center of the target image belongs to a preset range.
In this embodiment, based on the target image obtained in step 201, the executing entity may identify the target image to determine whether the distance between the display position of the target point in the target image and the center of the target image belongs to a preset range. The preset range may be a distance range preset by a technician, and when the distance between the display position of the target point in the target image and the center of the target image belongs to the preset range, it may be approximately determined that the display position of the target point in the target image coincides with the center of the target image.
here, the execution subject may determine a distance between a display position of the target point in the target image and a center of the target image. Specifically, the executing entity may identify the target image by using an image identification technology to determine position information (e.g., position coordinates) of a display position of the target point in the target image, and then determine a distance between the display position and a center of the target image by using the position information; alternatively, the executing entity may recognize the target image by using an image recognition technology to determine a target point in the target image, then connect the target point in the target image with the center of the target image, and determine the length of a line segment obtained by the connection as the distance between the display position of the target point in the target image and the center of the target image. It should be noted that the image recognition technology is a well-known technology that is widely researched and applied at present, and is not described herein again.
step 203, in response to determining that the distance between the display position of the target point in the target image and the center of the target image does not belong to the preset range, sending a moving instruction to the moving end to move the moving end to the target position.
In this embodiment, the executing body may send a moving instruction to the moving end to move the moving end to the target position in response to determining that the distance between the display position of the target point in the target image and the center of the target image does not belong to the preset range. The moving instruction may be used to instruct the moving terminal to move. The target position may be a position to which the moving end moves after receiving the moving instruction so that a distance between a display position of the target point in the captured image and the center of the captured image falls within a preset range.
it can be understood that, during the moving process of the moving end, the moving end may continuously shoot the target point and send the shot image to the execution main body, so that the execution main body identifies the shot image, determines the distance between the display position of the target point in the shot image and the center of the shot image, and further determines whether the moving end moves to the target position based on the determined distance. Specifically, as an example, the execution body described above may determine that the moving end moves to the target position in response to determining that the distance between the display position of the target point in the captured image and the center of the captured image belongs to a preset range. Here, in response to determining that the mobile terminal moves to the target position, the execution body may send a stationary command to the mobile terminal to cause the mobile terminal to be stationary at the target position.
Step 204, position information of the target position is acquired, and position information of the target point is generated based on the acquired position information.
In the present embodiment, the execution body described above may acquire position information of a target position, and generate position information of the target point based on the acquired position information. Wherein the location information may include, but is not limited to, at least one of: numbers, words, symbols, pictures. Specifically, the executing body may obtain the position information of the target position sent by the mobile terminal, or may locate the target position after determining the target position, so as to obtain the position information of the target position. It should be noted that, here, the mobile terminal may obtain the location information of its own location in real time through a preset positioning device. The positioning device may be software or hardware.
In some optional implementations of this embodiment, the executing body may obtain the position information of the target position by: first, every preset time period, the execution main body may obtain the location information of the location where the mobile terminal is located, so as to obtain a preset number of location information. Then, the execution body may generate the position information of the target position based on the obtained preset number of position information. For example, the execution subject may determine a position closest to the target point from among positions corresponding to a preset number of pieces of position information, and determine position information of the determined position as position information of the target position; or, the position information is a position coordinate of a position where the mobile terminal is located, and the execution main body may perform an average calculation on coordinate values of a preset number of obtained position coordinates, and determine a result coordinate obtained by the calculation as the position information of the target position.
It can be understood that, since the moving direction of the moving end is perpendicular to the shooting direction, when the distance between the display position of the target point in the target image and the center of the target image belongs to a preset range (approximately, the display position and the center coincide), that is, when the moving end moves to the target position, the moving end and the target point have the same position information in the direction perpendicular to the shooting direction, and the execution main body can determine the position information of the target point based on the position information of the target position.
In some optional implementations of the embodiment, the executing entity may generate the position information of the target point by: first, the execution body may determine an elevation value of the target location. Then, the execution subject may determine the elevation values of the target points based on the elevation values of the target positions, and determine the elevation values of the target points as position information of the target points.
As an example, the moving direction of the moving end is a horizontal direction, and the photographing direction is perpendicular to the moving direction. When the mobile terminal moves to the target position, the distance between the display position of the target point in the target image and the center of the target image belongs to a preset range (approximately the display position is coincident with the center), at this time, the execution main body can acquire the elevation value of the target position, determine the distance value between the target position and the target point, then calculate the difference between the acquired elevation value and the determined distance value, acquire the elevation value of the target point, and determine the acquired elevation value as the position information of the target point.
as another example, the shooting direction of the moving end is the horizontal direction, and the moving direction is perpendicular to the shooting direction. When the mobile terminal moves to the target position, the distance between the display position of the target point in the target image and the center of the target image belongs to a preset range (approximately coinciding with the display position and the center), at this time, the elevation value of the target position is the same as the elevation value of the target point, and the execution main body can acquire the elevation value of the target position, determine the acquired elevation value as the elevation value of the target point, and determine the determined elevation value of the target point as the position information of the target point.
In some optional implementations of this embodiment, the executing body may further generate the position information of the target point by: first, the execution body may determine plane coordinates of the target position. Then, the execution body may determine the plane coordinates of the target point based on the plane coordinates of the target position, and determine the plane coordinates of the target point as the position information of the target point.
as an example, the moving direction of the moving end is a horizontal direction, and the photographing direction is perpendicular to the moving direction. When the mobile terminal moves to the target position, the distance between the display position of the target point in the target image and the center of the target image belongs to a preset range (approximately the display position is coincident with the center), at this time, the plane coordinate of the target position is the same as the plane coordinate of the target point, and further, the execution main body can acquire the plane coordinate of the target position, determine the acquired plane coordinate as the plane coordinate of the target point, and determine the determined plane coordinate of the target point as the position information of the target point.
As another example, the shooting direction of the moving end is the horizontal direction, and the moving direction is perpendicular to the shooting direction. When the mobile terminal moves to the target position, the distance between the display position of the target point in the target image and the center of the target image belongs to a preset range (approximately the display position coincides with the center), at this time, the execution main body can acquire the plane coordinate of the target position, determine the distance value between the target position and the target point, then determine the plane coordinate of the target point based on the acquired plane coordinate and the determined distance value, and further determine the plane coordinate of the determined target point as the position information of the target point.
Specifically, when the shooting direction coincides with the x-axis of the coordinate system in which the plane coordinates are located, the coordinate value in the y-axis direction in the plane coordinates of the target point is the same as the coordinate value in the y-axis direction in the plane coordinates of the target position. For the coordinate value in the x-axis direction in the plane coordinate of the target point, the execution subject may perform a difference between the coordinate value in the x-axis direction in the obtained plane coordinate and the determined distance value to obtain the coordinate value in the x-axis direction in the plane coordinate of the target point, that is, obtain the plane coordinate of the target point; when the photographing direction coincides with the y-axis of the coordinate system in which the plane coordinates are located, the coordinate value of the x-axis direction in the plane coordinates of the target point is the same as the coordinate value of the x-axis direction in the plane coordinates of the target position. For the coordinate value in the y axis direction in the plane coordinate of the target point, the executing entity may perform a difference between the coordinate value in the y axis direction in the obtained plane coordinate and the determined distance value, obtain the coordinate value in the y axis direction in the plane coordinate of the target point, and further obtain the plane coordinate of the target point.
In some optional implementation manners of this embodiment, the executing body may further obtain, in response to determining that a distance between a display position of the target point in the target image and a center of the target image belongs to a preset range (approximately, the display position coincides with the center), position information of a position where the moving end is located, and generate the position information of the target point based on the position information of the position where the moving end is located. In this implementation, the location of the mobile terminal is equivalent to the target location in step 204, and the executing entity may further obtain the location information of the location of the mobile terminal by using the method described in step 204 and related to the target location, and generate the location information of the target point based on the location information of the location of the mobile terminal.
With continued reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of the method for generating location information according to the present embodiment. In the application scenario of fig. 3, the server 301 first receives a target image 303 sent by the drone 302, where the target image 303 is an image obtained by shooting a target point 304 by the drone. Next, the server 301 may identify the target image 303 to determine whether a distance between a display position of the target point 304 in the target image 303 and the center of the target image 303 belongs to a preset range. Then, in response to determining that the distance between the display position of the target point 304 in the target image 303 and the center of the target image 303 does not belong to the preset range, the server 301 may send a movement instruction 305 to the drone 302 to move the drone 302 to the target position at which the distance between the display position of the target point 304 in the captured image 306 and the center of the captured image 306 belongs to the preset range. Next, the server 301 may acquire the position information 307 of the target position transmitted by the drone 302, and generate the position information 308 of the target point 304 based on the acquired position information 307.
The method provided by the embodiment of the application enriches the generation mode of the position information by acquiring the position information of the target point through the mobile terminal, and can reduce the influence of the surrounding environment of the target point in the information acquisition process and improve the accuracy of information generation by acquiring the position information of the target point through the mobile terminal.
With further reference to fig. 4, a flow 400 of yet another embodiment of a method for generating location information is shown. The flow 400 of the method for generating location information comprises the steps of:
Step 401, receiving a target image sent by a mobile terminal.
in the present embodiment, the execution subject (e.g., the server shown in fig. 1) of the method for generating location information may receive the target image from the mobile terminal (e.g., the terminal device shown in fig. 1) through a wired connection manner or a wireless connection manner. The target image may be an image obtained by shooting the target point by the moving end. The target point may be a point whose position information is to be determined.
Step 402, identifying the target image to determine whether the distance between the display position of the target point in the target image and the center of the target image belongs to a preset range.
In this embodiment, based on the target image obtained in step 401, the executing entity may identify the target image to determine whether the distance between the display position of the target point in the target image and the center of the target image belongs to a preset range. The preset range may be a distance range preset by a technician, and when the distance between the display position of the target point in the target image and the center of the target image belongs to the preset range, it may be approximately determined that the display position of the target point in the target image coincides with the center of the target image.
And step 403, in response to determining that the distance between the display position of the target point in the target image and the center of the target image does not belong to the preset range, sending a moving instruction to the moving end to move the moving end, and acquiring a distance value between the display position of the target point in the shot image and the center of the shot image.
in this embodiment, the execution subject may send a movement instruction to the moving end to move the moving end in response to determining that the distance between the display position of the target point in the target image and the center of the target image does not belong to the preset range, and acquire a value of the distance between the display position of the target point in the captured image and the center of the captured image. The moving instruction may be used to instruct the moving terminal to move. It can be understood that, during the moving process, the moving end may continuously capture the target point and send the captured image to the executing entity, and the executing entity may continuously determine the distance value between the display position of the target point in the captured image and the center of the captured image.
in response to determining that the acquired distance values belong to the preset range, step 404 determines whether the acquired distance values within a preset time period from the current time all belong to the preset range.
In this embodiment, the executing body may determine whether the distance values acquired within the preset time period from the current time all belong to the preset range in response to determining that the currently acquired distance value belongs to the preset range. The preset time period may be any time period preset by a technician, for example, 10 minutes.
Step 405, in response to determining that the distance values acquired within the preset time period from the current time all belong to the preset range, determining that the mobile terminal moves to the target position.
in this embodiment, the executing body may determine that the mobile terminal moves to the target position in response to determining that the distance values acquired within the preset time period from the current time all belong to the preset range.
In particular, in response to determining that the mobile terminal moves to the target position, the execution body may send a stationary command to the mobile terminal to cause the mobile terminal to be stationary at the target position.
Step 406, position information of the target position is acquired, and position information of the target point is generated based on the acquired position information.
in the present embodiment, the execution body described above may acquire position information of a target position, and generate position information of the target point based on the acquired position information. Wherein the location information may include, but is not limited to, at least one of: numbers, words, symbols, pictures. Specifically, the executing body may obtain the position information of the target position sent by the mobile terminal, or may locate the target position after determining the target position, so as to obtain the position information of the target position. It should be noted that, here, the mobile terminal may obtain the location information of its own location in real time through a preset positioning device. The positioning device may be software or hardware.
it can be understood that, since the moving direction of the moving end is perpendicular to the shooting direction, when the display position of the target point in the target image coincides with the center of the target image, that is, when the moving end moves to the target position, the moving end and the target point have the same position information in the direction perpendicular to the shooting direction, and the execution subject can determine the position information of the target point based on the position information of the target position.
Step 401, step 402, and step 406 are respectively the same as step 201, step 202, and step 204 in the foregoing embodiment, and the above description for step 201, step 202, and step 204 also applies to step 401, step 402, and step 406, which is not described herein again.
As can be seen from fig. 4, compared with the embodiment corresponding to fig. 2, the flow 400 of the method for generating position information in the present embodiment highlights the step of determining whether the moving end moves to the target position by the distance value between the display position of the target point in the captured image and the center of the captured image within the preset time period. Therefore, the scheme described in this embodiment can determine the position to which the mobile terminal with a more stable moving state moves as the target position, so that more accurate position information can be generated.
with further reference to fig. 5, as an implementation of the method shown in the above-mentioned figures, the present application provides an embodiment of an apparatus for generating location information, which corresponds to the method embodiment shown in fig. 2, and which is particularly applicable to various electronic devices.
As shown in fig. 5, the apparatus 500 for generating location information of the present embodiment includes: an image receiving unit 501, an image recognizing unit 502, an instruction transmitting unit 503, and a first generating unit 504. The image receiving unit 501 is configured to receive a target image sent by a mobile terminal, where the target image is an image obtained by shooting a target point by the mobile terminal; the image recognition unit 502 is configured to recognize the target image to determine whether a distance between a display position of the target point in the target image and a center of the target image belongs to a preset range; the instruction transmitting unit 503 is configured to transmit a movement instruction to the moving terminal to move the moving terminal to the target position in response to a determination that the distance between the display position of the target point in the target image and the center of the target image does not belong to the preset range, wherein the target position is a position to which the moving terminal is moved such that the distance between the display position of the target point in the captured image and the center of the captured image belongs to the preset range; the first generation unit 504 is configured to acquire position information of a target position, and generate position information of the target point based on the acquired position information.
In this embodiment, the image receiving unit 501 of the apparatus 500 for generating location information may receive the target image from a mobile terminal (e.g., a terminal device shown in fig. 1) through a wired connection manner or a wireless connection manner. The target image may be an image obtained by shooting the target point by the moving end. The target point may be a point whose position information is to be determined.
Here, the moving terminal may obtain the target image in various ways. Specifically, as an example, when the mobile terminal is in a moving state, the image receiving unit 501 may continuously obtain an image captured by the mobile terminal for a technician to observe, and when the technician observes that a target point is included in the captured image, the technician may use the apparatus 500 to indicate that the mobile terminal has obtained a target image including the target point; or, the mobile terminal may move to an area for shooting the target point in advance, and then shoot the target point to obtain the target image.
The images (including the target image) captured by the moving end may be images of various shapes (e.g., a circle, a rectangle, a square, etc.) having a center. In addition, the moving direction of the moving end is perpendicular to the shooting direction in the process of shooting the target point.
In this embodiment, based on the target image obtained by the image receiving unit 501, the image recognition unit 502 may recognize the target image to determine whether a distance between a display position of the target point in the target image and a center of the target image belongs to a preset range. The preset range may be a distance range preset by a technician, and when the distance between the display position of the target point in the target image and the center of the target image belongs to the preset range, it may be approximately determined that the display position of the target point in the target image coincides with the center of the target image.
Here, the image recognition unit 502 may determine a distance between the display position of the target point in the target image and the center of the target image. Specifically, the image recognition unit 502 may recognize the target image by using an image recognition technology to determine position information (e.g., position coordinates) of a display position of the target point in the target image, and then determine a distance between the display position and the center of the target image by using the position information; alternatively, the image recognition unit 502 may recognize the target image by using an image recognition technology to determine the target point in the target image, and then connect the target point in the target image with the center of the target image, and determine the length of the line segment obtained by the connection as the distance between the display position of the target point in the target image and the center of the target image. It should be noted that the image recognition technology is a well-known technology that is widely researched and applied at present, and is not described herein again.
in this embodiment, the instruction transmitting unit 503 may transmit a movement instruction to the moving end to move the moving end to the target position in response to determining that the distance between the display position of the target point in the target image and the center of the target image does not belong to the preset range. The moving instruction may be used to instruct the moving terminal to move. The target position may be a position to which the moving end moves after receiving the moving instruction so that a distance between a display position of the target point in the captured image and the center of the captured image falls within a preset range.
In the present embodiment, the first generation unit 504 may acquire position information of the target position, and generate position information of the target point based on the acquired position information. Wherein the location information may include, but is not limited to, at least one of: numbers, words, symbols, pictures. Specifically, the first generating unit 504 may obtain the position information of the target position sent by the mobile terminal, or may locate the target position after determining the target position, so as to obtain the position information of the target position. It should be noted that, here, the mobile terminal may obtain the location information of its own location in real time through a preset positioning device. The positioning device may be software or hardware.
It is to be understood that, since the moving direction of the moving end is perpendicular to the shooting direction, when the distance between the display position of the target point in the target image and the center of the target image belongs to a preset range (approximately, the display position coincides with the center), that is, when the moving end moves to the target position, the moving end and the target point have the same position information in the direction perpendicular to the shooting direction, and the first generating unit 504 can determine the position information of the target point based on the position information of the target position.
In some optional implementations of this embodiment, the apparatus 500 may further include: and a second generating unit configured to acquire position information of a position where the moving end is located in response to a determination that a distance between a display position of the target point in the target image and a center of the target image belongs to a preset range, and generate the position information of the target point based on the position information of the position where the moving end is located.
in some optional implementations of this embodiment, the instruction sending unit 503 may include: the distance acquisition module is configured to send a movement instruction to the mobile terminal so as to enable the mobile terminal to move, and acquire a distance value between a display position of a target point in the shot image and the center of the shot image; a distance determination module configured to determine whether the acquired distance values within a preset time period from a current time all belong to a preset range in response to a determination that the acquired distance values belong to the preset range; and the position determining module is used for determining that the mobile terminal moves to the target position in response to the fact that the distance values acquired within the preset time period from the current moment are within the preset range.
In some optional implementations of the present embodiment, the first generating unit 504 may include: the information acquisition module is configured to acquire the position information of the position of the mobile terminal every preset time period so as to acquire the position information of a preset number; an information generating module configured to generate position information of the target position based on the obtained preset number of position information.

In some optional implementations of the present embodiment, the first generating unit 504 may be further configured to: determining plane coordinates of a target position; determining planar coordinates of the target point based on the planar coordinates of the target position, and determining the planar coordinates of the target point as position information of the target point.
The apparatus 500 provided in the above embodiment of the present application receives, by the image receiving unit 501, a target image transmitted by a mobile terminal, where the target image is an image obtained by shooting a target point by the mobile terminal, then the image recognizing unit 502 recognizes the target image to determine whether a distance between a display position of the target point in the target image and a center of the target image belongs to a preset range, then the instruction transmitting unit 503 transmits a movement instruction to the mobile terminal to move the mobile terminal to the target position in response to determining that the distance between the display position of the target point in the target image and the center of the target image does not belong to the preset range, and finally the first generating unit 504 acquires position information of the target position and generates position information of the target point based on the acquired position information, thereby effectively utilizing the mobile terminal to acquire the position information of the target point, the generation mode of the position information is enriched, and the influence of the surrounding environment of the target point in the information acquisition process can be reduced by acquiring the position information of the target point through the mobile terminal, so that the accuracy of information generation is improved.
