Title:
MAP UPDATING METHOD, ROBOT, AND READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/005021
Kind Code:
A1
Abstract:
Provided are a map updating method, a robot, and a computer-readable storage medium, which are applicable to the technical field of robots. The method comprises: obtaining each first key frame collected by a robot during movement (S101); processing each first key frame on the basis of each first key frame and each second key frame of an initial map stored by the robot to obtain an optimized key frame of each first key frame (S102); and updating the initial map on the basis of the optimized key frame to obtain an updated initial map (S103). By means of the method, each first key frame is jointly processed by using each first key frame and each second key frame in an initial map, so that the obtained optimized first key frame can be more accurate, thereby achieving the aim of more accurately updating the initial map.
