Camera linkage method, device, equipment and storage medium based on 3D map

Abstract

The invention discloses a camera linkage method, device and equipment based on a 3D map, and a storage medium, and the method comprises the steps: detecting a frame selection operation on a screen, and determining a screen frame selection area in response to the frame selection operation; wherein a 3D map is displayed on the screen; acquiring a corresponding selected area on the 3D map according to the screen frame selected area; according to the geographic position information of the selected area and the geographic position information of the camera, calculating the orientation and multiplying power of the camera when monitoring the selected area; adjusting the magnification of the camera according to the calculated magnification of the camera, and controlling the camera to turn to a live-action area corresponding to the selected area according to the calculated orientation of the camera. According to the method, 3D positioning and camera linkage interaction can be achieved, the monitoring view angle of the camera can be accurately controlled, the condition of the to-be-monitored area is obtained in real time, and the user experience is improved.

Description

technical field [0001] The present invention relates to the field of computer graphics processing, in particular to a 3D map-based camera linkage method, device, equipment and computer-readable storage medium. Background technique [0002] 3D map is one of the methods of map display. It is based on the latest technologies such as WEB GIS geographic information system, GPS global satellite positioning system, RS remote sensing system, and VR panorama. It uses 3D modeling of urban buildings as a carrier to integrate local urban buildings. The most intuitive electronic map, also called three-dimensional map, three-dimensional map, virtual city, can intuitively display the overall situation of the area to be monitored, but the existing 3D map cannot Real-time access to the situation of the area to be monitored. [0003] Most of the existing monitoring is directly based on video. At present, there is a form of adding labels on the 3D map to display the object information in the ...

[0002] 3D map is one of the methods of map display. It is based on the latest technologies such as WEB GIS geographic information system, GPS global satellite positioning system, RS remote sensing system, and VR panorama. It uses 3D modeling of urban buildings as a carrier to integrate local urban buildings. The most intuitive electronic map, also called three-dimensional map, three-dimensional map, virtual city, can intuitively display the overall situation of the area to be monitored, but the existing 3D map cannot Real-time access to the situation of the area to be monitored

[0003] Most of the existing monitoring is directly based on video. At present, there is a form of adding labels on the 3D map to display the object information in the monitoring screen. However, this monitoring method is still based on video, and it is impossible to view the area to be monitored. The current situation does not meet people's viewing needs for 3D maps
