Claim 0:
1. A self-adaptive point cloud stripe division method, specifically comprising the following steps:
1) Preliminarily dividing point cloud to obtain local point clouds: reading in a point cloud to be processed, preliminarily dividing geometric space of the point cloud, and then obtaining one group of local point clouds with an order by sorting;
2) Comparing number of points of the local point clouds with a limited range: due to transmission requirement and bandwidth limitation, the number of points in a point cloud stripe which supports parallel processing needing to meet a limited range, wherein upper limit and lower limit of the number of points are maxSize and minSize respectively;
3) Redividing or re-fusing the local point clouds to obtain a final point cloud stripe: on the basis of local point cloud division, redividing the local point cloud beyond the upper limit of the number of points, and fusing the local point cloud with the number of points less than the lower limit to obtain a point cloud stripe with the number of points meeting the limited range; redividing the local point cloud with the number of points exceeding the upper limit at intervals of maxSize to obtain one new group of local point clouds, wherein all the local point clouds are obtained through iterating; for the local point clouds with the number of points less than the lower limit, combining point cloud distribution and Morton code order, selecting to perform forward local point cloud fusion or backward local point cloud fusion;
(4) obtaining a point cloud stripe with the number of points meeting the limited range.
