Embodiment Construction
[0023] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
[0024] like figure 1 As shown, in this embodiment, the following steps are included:
[0025] Step S1: obtaining the drone point cloud data of the target through the drone;
[0026] Step S2: obtaining the three-dimensional laser point cloud data of the target through a three-dimensional laser scanner;
[0027] Step S3: Convert the 3D laser point cloud data and the UAV point cloud data into the same format;
[0028] Step S4: Using the drone point cloud data as the reference system and the 3D laser point cloud data as the mobile system, select multiple points with the same name based on the RGB color type based on the 3D point cloud data, and use the global matching method to match the point clouds of the two. Data builds correlation matching.
[0029] like figure 2 As shown, in this embodiment, the three-dimensional laser point clo...
