Claim 3:
4. The point cloud stripe division method according to claim 1, characterized by a threshold thres of the number of points beyond standard ratio ratio of the local point cloud being set when the number of points of the local point cloud is compared with the limited range in step 2); iterating all local point clouds obtained in step 1), and comparing a size relation of the number of points in each local point cloud with an upper range limit maxSize; when the number of points of the local point cloud exceeds maxSize, adding 1 to a counter num, and after the iteration is completed, calculating a proportion ratio of the local point cloud where the number of points exceeds maxSize; if the proportion ratio exceeds the threshold thres, then the current local point cloud structure being spatially divided; if the proportion ratio does not exceed the threshold thres, preliminary space division being completed such that the structure of the current local point cloud is kept and the next operation is carried out.
