Abstract
Embodiments of the present invention disclose a method and device for constructing a spatial index of massive point cloud data. The method includes: partitioning acquired original point cloud data to obtain a plurality of point cloud data blocks; constructing an octree index of a current point cloud data block for each point cloud data block; and merging the octree indexes of the plurality of point cloud data blocks to obtain a spatial index structure of the original point cloud data.
