Algorithm 1 Octree-based point cloud simplification algorithm

---

Input: Original point cloud (P)

Output: Point cloud of Octree simplification (O)

1. Set the octree resolution (voxel size)

2. Divide O into voxel cubes (C) by voxel segmentation until the specified voxel size is reached

3. Calculate the voxel center of C

4. Traverse all the voxel centers

5. For:  i = 0, 1….voxel_centers.size() - 1

6. Construct a new point cloud by voxel centers
