Embodiment 1
[0069] Such as Figure 1 to Figure 10 As shown, a mining area FVC calculation method that enhances edge sampling and improves the Unet model, the method is as follows:
[0070] A. Data collection of ground vegetation parameters in the mining area scene: determine the mining area research area, use drones to take overlapping orthophoto aerial photography of the mining area research area according to the mapping accuracy and obtain the orthophoto set. The minimum overlapping ratio of the aerial photography is 32-38% ( To design the flight plan, first survey the entire research area on the spot, clarify the terrain of the research area, conduct simulation planning for the take-off, landing, and flight of the UAV, and then divide the entire research area into multiple flights with overlapping areas on the device The survey area, the overlapping ratio of the area depends on the demand for data accuracy, preferably 35%), then image stitching is performed to obtain the orthophoto ima...
Embodiment 2
[0087] Such as Figure 1 to Figure 10 As shown, a mining area FVC calculation method that enhances edge sampling and improves the Unet model, the method is as follows:
[0088] A. Data collection of ground vegetation parameters in the mining area scene: Determine the mining area research area, use drones to take overlapping orthophoto aerial photography of the mining area research area according to the mapping accuracy and obtain an orthophoto set. The mapping accuracy is centimeter level, and the minimum overlapping ratio of aerial photography 32-38%, then image stitching is performed to obtain the orthophoto image of the research area, and then the spatial three-dimensional solution model SFM is established to generate dense point cloud data, which is transformed to obtain high-precision digital geographic elevation model data;
[0089] According to a preferred embodiment of this embodiment, in step A, according to the mapping accuracy of the orthophoto set, flight planning ...
