Distribution of sampling points in the source point cloud. (a) and (c) are the sampling points before the first filtering of experiments 1 and 2, respectively; (b) and (d) are the sampling points after the first filtering of experiments 1 and 2, respectively. The red areas are the strip overlap areas, and the yellow points are the sampling points of the source point cloud.
