At present, in the field of security protection, the following three security protection methods are used for the security protection of parks and streets, and there are mainly the following problems:

First, in the current usage scenarios of intelligent edge node products, the concept of the Internet of Things is introduced, and the cloud/device center is used to connect edge nodes. However, due to the lack of edge devices' own perception capabilities, various edge intelligent terminal devices In fact, it is still in a state of information island, which leads to the fact that the information of various edge devices cannot be effectively correlated for data mining and utilization.

The second aspect is that in the design of the current park/city street monitoring system, the selection of camera points and the evaluation of the monitoring effect after installation are extremely dependent on the monitoring plan during the construction phase/the experience of the construction personnel. Insufficient understanding of the park/monitoring area, the following problems are prone to occur: 1) The installation angle or installation point of the surveillance camera is missing, resulting in a monitoring dead angle. 2) The installation distance of the monitoring camera is not suitable, which will cause the shooting target to exceed the optimal monitoring distance, which will cause the target image to be unclear.

On the third aspect, in the daily monitoring work of the park, especially when there are dynamic mobile devices such as ball machines in the monitoring system, the security personnel cannot dynamically, intuitively and quickly understand the monitoring coverage status of the current park by the monitoring system. It is still necessary to rely on long-term experience to judge or increase manual patrol coverage.

In view of the above problems in the security field, the embodiments of the present disclosure provide a map generation solution, by acquiring the pose information and shooting field information corresponding to multiple collection devices in the target scene, and then according to the pose information of each collection device Information and shooting field of view information, determine the shooting area of each acquisition device, so that the shooting area of each acquisition device can be drawn on the electronic map of the target scene, and the layout map of the target scene can be generated. It can be used in security systems, multi-camera networking, edge nodes and other scenarios. For example, in open scenes such as squares, parks, classrooms, etc., multiple cameras can be set up, and by obtaining the pose information and shooting field information of multiple cameras, a cloth drawing the shooting areas of each camera in the scene can be generated in real time. Put a map. It can integrate the information of multiple collection devices in the target scene, effectively correlate the information of multiple collection devices, and provide users with real-time and intuitive information about the target scene by deploying the map, saving the human resources of security personnel, providing Provide effective support for the security protection of target scenarios

The map generation method provided by the embodiments of the present disclosure may be executed by a terminal device, a server, or other types of electronic devices, where the terminal device may be a user equipment (User Equipment, UE), a mobile device, a user terminal, a terminal, a cellular phone, a cordless Phones, Personal Digital Assistants (PDAs), handheld devices, computing devices, in-vehicle devices, wearable devices, etc. In some possible implementations, the map generation method may be implemented by a processor invoking computer-readable instructions stored in a memory. Alternatively, the method may be performed by a server.

FIG. 1 shows a flowchart of a map generation method according to an embodiment of the present disclosure. As shown in FIG. 1 , the map generation method can be applied to a server device, including:

Step S11 , acquiring the pose information and the shooting field of view information corresponding to the plurality of collecting devices in the target scene respectively.

In this embodiment of the present disclosure, multiple collection devices may be set in the target scene. The collection device may be a device with an image collection function, for example, the collection device may be a terminal device, a server, etc. with a shooting function, and each collection device may shoot a target scene. Multiple acquisition devices can communicate with each other to form a camera network, and information from different acquisition devices can be shared. The server device can obtain the pose information and shooting field information corresponding to the multiple collection devices in the target scene respectively, that is, obtain the pose information and shooting field information of each collection device in the target scene. In some implementation manners, the server device may obtain the pose information and shooting field information of each acquisition device from each acquisition device through the network. In some implementation manners, the server device may pre-store the pose information of each collection device and at least part of the shooting field of view information. For example, the server device may pre-store the geographic location of each capture device, and then obtain the information from each capture device. Other information other than the geographic location in the pose information and the shooting field of view information.

Here, the pose information may include geographic location and orientation, wherein the geographic location may indicate the location of the collection device in the electronic map of the target scene, and the geographic location may be latitude and longitude coordinates or location coordinates in the coordinate system of the electronic map. The orientation can indicate the orientation of the collection device. Each collection device can be rotated within a preset angle range. The orientation is different, and the pictures captured by the collection device are also different. The orientation can be expressed as a geographic direction or in the coordinate system of the electronic map. direction. The shooting field of view information may indicate the shooting field of view of the collection device, and the shooting field of view information may include a field of view angle, which may be relative to the orientation of the collection device. For example, based on the orientation of the collection device, the field of view may indicate a deviation from the orientation. For example, if the azimuth of the acquisition device is 0 and the field of view is (-30°, 30°), it can indicate that the field of view of the acquisition device is within an angular range of ±30° from the azimuth of the acquisition device.

Here, the server device may be a control device used to manage multiple collection devices, for example, a server, a control terminal, etc. The server device may summarize the information of multiple collection devices and issue some control commands to the multiple collection devices . In some implementation manners, the server device may be any one of the multiple collection devices, so that one of the multiple collection devices can aggregate the information of the multiple collection devices and control other collection devices. In this way, it can be applied to various application scenarios.

FIG. 2 shows a scene diagram of interaction between a server device and multiple collection devices according to an embodiment of the present disclosure. In some examples, for example, in the usage scenario of edge devices, the connection of each edge device (collection device) can be realized through the cloud device/central device (server device), and the cloud device/central device can aggregate multiple edge devices information, and issue control commands, such as rotation commands or parameter adjustment commands, to multiple edge devices (collection device 1-collection device 5), so as to reduce the influence of the lack of the edge device's own perception ability, and realize the Effective association of information.

Step S12: Determine the shooting area of each of the collection devices according to the pose information and the shooting field of view information of each of the collection devices.

In the embodiment of the present disclosure, the server device can determine the area corresponding to the field of view that can be captured by each capture device according to the pose information and the shooting field of view information of each capture device, and the region can be the capture area of the capture device. In some implementations, the shooting area can be a general area. For example, the geographic location of the capture device can be used as the center point, and a plurality of straight lines can be set through the center point. These straight lines can evenly divide the target scene into several areas. At least one area that may be located in the photographing field of view of the collecting device is roughly determined according to the orientation and viewing angle of the collecting device, and these areas can be used as the photographing area of the collecting device.

In some implementation manners, the shooting area corresponding to the shooting field of view of each collecting device may also be accurately determined according to the pose information and shooting field information of each collecting device. The server device can determine the shooting angle range of the acquisition device according to the azimuth and field of view of the acquisition device. For example, the azimuth of the acquisition device can be used to transform the field of view, such as increasing or decreasing the azimuth of the acquisition device based on the field of view. Corresponding angle, the shooting angle range of the acquisition device can be obtained. Assuming that the azimuth of the acquisition device is 90° (with true north as 0°) and the viewing angle is (-30°, 30°), the shooting angle range is (60°) , 120°). The shooting angle range may be the range of the shooting field of view of the acquisition device that corresponds to the geographic azimuth or the range that corresponds to the azimuth under the target scene coordinate system. Further, the shooting area of each collecting device can be determined according to the geographic location of the collecting device and the shooting angle range. For example, two rays can be drawn with the geographic location of the collecting device as the center and the azimuth formed by the shooting angle range as the side. The area formed by the rays can be determined as the shooting area of the acquisition device. In this way, the shooting area corresponding to each collecting device can be determined more accurately.

Step S13: Draw the shooting area of each of the collection devices on the electronic map of the target scene, and generate a deployment map of the target scene.

In the embodiment of the present disclosure, the shooting area of each acquisition device can be drawn on the electronic map of the target scene. For example, the shooting area of each acquisition device can be drawn on the electronic map by using different colors or indicators to generate a layout map of the target scene. , the shooting areas of different collection devices can be distinguished by color or indicator. In some implementations, if different shooting areas overlap, the overlapping areas can also be marked on the electronic map. mark.

Furthermore, the generated deployment map can be displayed, so that the deployment map can display the deployment situation of the target scene in real time, and the user can intuitively and quickly understand the security status of the target scene, which provides a basis for the security protection of the target scene. In some implementations, the generated deployment map can also be sent to the web page or client, so that the user can view the deployment map of the target scene by logging in to the corresponding web page or client, so that the user can quickly understand the deployment status of the target scene. Reduce deployment dead spots and loopholes.

In some implementations, the server device can repeatedly acquire the pose information and shooting field information of multiple acquisition devices in the target scene periodically or non-periodically, so that the pose information of multiple acquisition devices in the target scene can be continuously acquired according to the continuous acquisition. Information and shooting field of view information, update the deployment map in real time, so that the security status of the target scene can be displayed in real time.

Here, the electronic map of the target scene can be a map established in the world coordinate system, the coordinate points in the electronic map can be expressed as latitude and longitude coordinates, and the geographic location of the acquisition device can also be latitude and longitude coordinates, so that the shooting area of the acquisition device can be directly drawn on the electronic map. In some implementations, the electronic map may also be a map established in a relative coordinate system, and the coordinate points in the electronic map may be expressed as relative coordinates in the relative coordinate system. In this case, if the geographic location of the collection device is the latitude and longitude coordinates , then according to the coordinate transformation relationship between the relative coordinate system and the world coordinate system, the geographic location of the acquisition device is transformed from the latitude and longitude coordinates to the relative coordinate system of the electronic map, and the shooting area of the acquisition device is further drawn in the electronic map.

The embodiments of the present disclosure can draw the shooting areas of the multiple collecting devices on the electronic map of the target scene through the pose information and shooting field information of the multiple collecting devices, obtain the deployment map of the target scene, and realize the security protection of the target scene. The acquisition device can be used as an edge node in the edge device scenario, so that the information of each edge device can be effectively associated, compared with some solutions in the related art that are difficult to effectively utilize the information of the edge device due to the lack of the edge device's own perception ability. , which can enhance the effective use of information from edge devices.

In some implementations, when the server device acquires the pose information and the shooting field of view information from multiple collection devices, the server device may send the acquisition request in a broadcast manner, so that the multiple acquisition devices return based on the acquisition request. pose information and the shooting field of view information. Alternatively, the server device may send an acquisition request to multiple acquisition devices, so that the multiple acquisition devices return the pose information and the shooting field of view information based on the acquisition request.

Here, in the case where the server device sends the acquisition request by broadcasting, the acquisition device can monitor the server device. In the case of monitoring the acquisition request sent by the server device, the acquisition device returns itself to the server device according to the acquisition request. pose information and shooting field of view information. In this case, the server device may not need to store the device list of the acquisition device in advance. In some implementation manners, the server device can obtain the device lists of multiple collection devices in advance, and then send an acquisition request according to the collection device indicated in the device list. When the collection device receives the acquisition request, it can return itself to the server device. pose information and shooting field of view information. In this case, the acquisition device may not need to monitor the server device in real time.

In some implementations, a global navigation satellite system (Global Navigation Satellite System, GNSS) and an electronic compass sensor may be configured in the acquisition device, so that the acquisition device may have the ability to perceive its own geographic location and orientation. The acquisition device can obtain high-precision latitude and longitude coordinates through GPS differential or static positioning algorithms. In some implementations, after the installation of the acquisition device in the camera network is completed, the location of the acquisition device can no longer be changed, so that after the acquisition device is installed, the logical location of the acquisition device can be saved in the acquisition device or in the in the server device. Correspondingly, the coordinates of the electronic map can also be longitude and latitude coordinates, so that the acquired location information and the location information of the electronic map can be unified, which is convenient for other devices to use.

In some implementations, the acquisition device determines the field of view and the optimal shooting distance by using camera parameters such as the size, resolution, and focal length of the photosensitive device. The imaging quality of the acquisition camera is relatively high in the case of photographing the angle of view of the acquisition camera and the photographing pair within the optimal shooting distance. The acquisition device can record its own viewing angle and optimal shooting distance.

In the above step S12, the server device may determine the shooting area of each collecting device according to the pose information and the shooting field of view information of each collecting device. In some implementations, the shooting field information may also include the best shooting distance. When determining the shooting area of each acquisition device, a fan-shaped area formed with the geographical location of the acquisition device as the vertex can be determined according to the geographical location of the acquisition device, the range of the shooting angle, and the optimal shooting distance, and the fan-shaped area can be determined as the acquisition The shooting area of the device.

Here, the optimal shooting distance may represent the maximum distance between the shooting object in the target scene and the acquisition device under the condition that the imaging of the acquisition device is clear. The acquisition device can clearly capture the subject within the optimal shooting distance, and the subject can be a person or object in the target scene. If the optimal shooting distance is exceeded, the shooting picture of the capture device may be blurred. Therefore, in order to improve the clarity of the image captured by the capture device, the optimal capture distance of the capture device may also be considered when the capture area of each capture device is determined. For example, a sector may be formed with the geographic location of the collection device as the center, the optimal shooting distance as the radius, and the shooting angle range as the vertex angle, and the fan-shaped area may be the shooting area of the collection device. The shooting area determined in this way takes into account the optimal shooting distance of each collection device, and the people or objects captured in the shooting area can be clearly imaged, thereby improving the clarity of the image captured by the collection device.

In some implementation manners, in order to better provide users with the deployment situation of the target scene, at least one of the shooting blind area and the non-optimal shooting area of the target scene may also be determined according to the shooting areas of multiple acquisition devices, and further At least one of the determined shooting blind area and the non-optimal shooting area is prompted in the generated deployment map. Here, the shooting blind area may be an area in the target scene that cannot be photographed by multiple acquisition devices. The server device can determine the shooting blind spots in the target scene that cannot be captured by multiple acquisition devices according to the shooting angle range corresponding to the shooting area of each acquisition device and the occlusion of the buildings and infrastructure in the target scene to the shooting field of view of the acquisition device. . Correspondingly, the non-optimal shooting area may be an area in the target scene that exceeds the optimal shooting distances of the multiple capture devices. The server device can determine that it is within the shooting field of view of multiple collection devices but exceeds the shooting field of view of multiple collection devices according to the optimal shooting distance corresponding to the shooting area of each collection device and the occlusion of buildings and infrastructure in the target scene to the shooting field of view of the collection device. Capture the area where the device's best shooting distance is. When it is determined that there is at least one of a shooting blind spot and a non-optimal shooting area in the target scene, at least one of the shooting blind area and the non-optimal shooting area can be prompted in the deployment map, for example, by Graphics such as arrows and circles can indicate at least one of shooting blind spots and non-optimal shooting areas, or you can draw at least one of shooting blind spots and non-optimal shooting areas in the layout map, so that you can Better provide users with the deployment situation of the target scene by deploying the map.

In some examples, when it is determined that there is a shooting blind spot in the target scene, the server device may generate a rotation instruction based on the position information of the shooting blind spot, and send the rotation instruction to at least one of the multiple collection devices, so that at least One acquisition device is rotated toward the shooting blind area, thereby changing the orientation of at least one acquisition device. Here, the server device can pre-store the maximum shooting field of view of each acquisition device, and the maximum shooting field of view is the largest area that can be covered by the shooting area of the acquisition device when the acquisition device is rotatable, that is, the shooting area of the acquisition device follows the acquisition device. The maximum area that can be reached by changing the orientation. In some implementation manners, the maximum shooting field of view of each collection device may also be stored in the respective collection device, and the server device may obtain the maximum shooting field of view of each collection device from each collection device. The server device can determine one or more acquisition devices whose maximum shooting field of view includes the shooting blind area according to the location of the maximum shooting field of view of each acquisition device and the location of the shooting blind area, and then can send rotation to the determined one or more acquisition devices. an instruction to rotate the determined one or more acquisition devices toward the shooting blind spot. In this way, when there is a shooting blind spot in the target scene, the acquisition device can be adjusted in orientation, and the existence of the shooting blind spot can be reduced.

Correspondingly, the acquisition device can receive the rotation instruction sent by the server device, and then can obtain the position information of the shooting blind spot in the target scene according to the rotation instruction, and can further determine the rotation direction and rotation angle according to the position information of the shooting blind spot, and then according to the determined position information. The rotation direction and rotation angle are rotated towards the shooting blind spot, so that the shooting blind spot can enter the shooting field of view, thereby reducing the existence of the shooting blind spot.

In some examples, when the camera parameters of the acquisition device are adjustable, the optimal shooting distance of the acquisition device can be changed with the adjustment of the camera parameters, and correspondingly, the maximum shooting field of view of the acquisition device can be changed according to the optimal shooting distance and change. In some examples, the maximum shooting field of view of the acquisition device may also be marked, for example, a dotted line may be used to mark the maximum shooting field of view of the acquisition device.

In some examples, when it is determined that there is a non-optimal shooting area in the target scene, the server device may generate a parameter adjustment instruction, and send the parameter adjustment instruction to at least one acquisition device among the plurality of acquisition devices, so as to expand at least one of the acquisition devices. A shooting area of a capture device, which can reduce the existence of non-optimal shooting areas in the target scene and improve the deployment effect.
