Claim 5:
6. The point cloud stripe division method according to claim 1, characterized in that a method for re-fusing the re-segmented local point clouds in step 3) comprises iterating all local point clouds according to the order of the Morton code, wherein the local point cloud bi with less number of points than minSize needs to be re-fused, and the fusion direction can be selected from forward fusion or backward fusion, wherein
assuming that the number of points of local point cloud after forward fusion is bi(mergeFront) and the number of points of local point cloud after backward fusion is bi(mergeNext), selection principle of a fusion direction is as follows:
(1) if bi(mergeFront)>maxSize and bi(mergeNext)>maxSize, the direction is selected to be max (bi(mergeFront), bi(mergeNext));
(2) if bi(mergeFront)>maxSize and bi(mergeNext)>maxSize, the direction is selected to be max (bi(mergeFront), bi(mergeNext));
(3) in other cases, the direction is selected to be min (bi(mergeFront), bi(mergeNext)).
