Abstract:
A grid map correction method and device, and a storage medium and an electronic device. The method comprises: in the process that a mobile robot is controlled to advance in a target area, constructing a grid map of the target area on the basis of first point cloud data collected by a target component (S202); establishing an obstacle map of the target area according to image data collected by an image collection assembly and second point cloud data collected by a line laser assembly, wherein the obstacle map at least comprises the type of an obstacle and the position of the obstacle in the target area (S204); and correcting the grid map according to the obstacle map to obtain a corrected grid map (S206).
