Abstract
A point cloud matching method and apparatus, an electronic apparatus, and a storage medium are provided. The point cloud matching method includes: dividing a to-be-matched point cloud into a plurality of matched point cloud patches, and inputting the plurality of matched point cloud patches to a pre-trained point cloud feature coding module to obtain feature vectors of the plurality of matched point cloud patches; and acquiring a global description vector of the to-be-matched point cloud according to the feature vectors of the plurality of matched point cloud patches, matching the global description vector of the to-be-matched point cloud with global description vectors of point cloud frames in a preset historical database, and determining a point cloud frame in the historical database within a preset matching threshold range to be a point cloud matching result.
