Embodiment 1
[0046] A three-dimensional grid-based airborne laser radar point cloud denoising method, comprising the following steps:
[0047] A. The present invention has adopted the reference data issued by ISPRS as experimental data, and selected 3 groups of different point cloud data for experimentation;
[0048]B has cut the selected data to meet the experimental requirements. Both sample 1 and sample 2 selected forest point clouds with undulating terrain. meters), the sample 3 selects the point cloud data of villages and towns with flat terrain, the number and density of point cloud points are: 179451 (15.385 per square meter), and each point cloud contains different numbers of discrete noise points and cluster noise point.
[0049] C determines the grid spacing according to the average point spacing of point cloud data points and related parameters;
[0050] D segment the x, y, and z directions of the circumscribed cuboid of the point cloud data, and establish a three-dimensional ...
