Point cloud map segmentation method and device, electronic equipment and storage medium

The invention discloses a point cloud map segmentation method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining the coordinate data and the number of point clouds of a current target point cloud map, enabling an initial target point cloud map to be a global point cloud map, and determining whether to carry out the map segmentation or not according to the coordinate data, the number of point clouds, a preset width threshold value and a preset point cloud threshold value; if not, outputting a target point cloud map; if yes, coordinates and directions of a segmentation axis are determined based on the coordinate data and the number of the point clouds, and the segmentation axis is perpendicular or parallel to the coordinate axis; carrying out map segmentation on the target point cloud map by adopting a segmentation axis to obtain point cloud sub-images; and taking the point cloud sub-graph as a new target point cloud map. After the map is segmented, the robot on
