Abstract
Embodiments of the present application disclose a local map updating method and apparatus, and an electronic device, including: acquiring key-frame point cloud data, where the key-frame point cloud data includes point cloud coordinate points; matching the key-frame point cloud data with a prior map to determine target voxels, in the prior map, corresponding to the point cloud coordinate points; and updating a point cloud probability distribution corresponding to each target voxel according to a first map coordinate point and a second map coordinate point included in each target voxel to obtain a target map, where the first map coordinate point is obtained by converting the point cloud coordinate point corresponding to the target voxel, and the second map coordinate point is a coordinate point included in the target voxel in the prior map.
