[0119] In order to reflect the practical value of the method in this paper, the suspected illegal construction behavior of tower base video supervision in the field of natural resource monitoring and supervision is used as the basic scene of the experiment, and the Nanjing Jiangxinzhou area is selected as the experimental area, and the high-tower camera is used as the basic experimental video source. The basic form of constructing a 3D virtual geographic environment is to construct a 3D virtual geographic scene based on 4D products. The input data includes NASA Earth Data 12.5M spatial resolution DEM data, and high-resolution remote sensing image data is selected from Tiandi Remote Sensing Image Data. Use the surveying and mapping method to collect the position of the camera, import the data into the SuperMap platform, analyze the video image and fuse it with the 3D scene to construct a 3D real-scene fusion scene.
[0120] This example realizes the target recognition and spatia...
