Document Type and Number:
WIPO Patent Application WO/2021/233452
Kind Code:
A1
Abstract:
A map updating method and apparatus. The map updating method comprises: establishing an update path which starts from a first effective map node to a second effective map node and passes a map node to be updated, controlling a mobile robot to move according to the update path, and when the distance between the current position of the mobile robot and the map node to be updated is less than a set distance threshold value, triggering the collection of motion information of the current position, and taking the current position as an updated map node position; and during a moving process, collecting motion information of a first effective map node position and a second effective map node position, figuring out global posture information of the updated map node on the basis of the motion information of the first effective map node position and the second effective map node position, deleting map information of the map node to be updated in a map, and storing map information of the updated map node. By means of the map updating method, update processing of a map node can be automatically completed in real time without manual intervention.
