Abstract
The present disclosure discloses a method and an apparatus for point cloud registration. The method includes: segmenting a source point cloud and a destination point cloud respectively into different categories of attribute features based on semantic; segmenting the source point cloud and the destination point cloud into a plurality of grids based on the attribute features; calculating a current similarity between the source point cloud and the destination point cloud based on the plurality of grids; determining whether the current similarity and a current iterative number satisfy a preset condition; when the current similarity and the current iterative number satisfy the preset condition, performing a registration on the source point cloud and the destination point cloud to obtain a registered result; and based on the registered result, adjusting a position of the source point cloud, updating the current iterative number.
