Data processing method and system

Abstract

The embodiment of the present specification provides a data processing method and system, the data processing method comprises: acquiring a point cloud data file, the point cloud data file containing point cloud data stored by at least two point cloud data blocks associated with a target scene. At least two point cloud data blocks are obtained by performing point cloud slicing on the target scene. A sampling strategy is set for the point cloud data in the point cloud data file, and distribution information is configured for the point cloud data according to the sampling strategy and a preset data distribution. The point cloud data and the distribution information are matched with a tree structure according to the distribution information, so that the point cloud data can be stored in an orderly manner according to the node arrangement structure in the tree structure, and the query efficiency of the point cloud data is improved. A point cloud data table corresponding to the target scene is constructed based on the attribute information of the point cloud data and the target point cloud data matched with the tree structure. The ordered point cloud data table can improve the query efficiency and accuracy of subsequent point cloud data query.
