Document Type and Number:
WIPO Patent Application WO/2023/109347
Kind Code:
A1
Abstract:
A relocalization method for a self-moving device, a device, and a storage medium. The relocalization method comprises: in response to an instruction of performing relocalization on a self-moving device in a working region, obtaining current environment information that is acquired by the self-moving device on the basis of a current position (S201); identifying the current environment information to obtain region identifier information corresponding to the current environment information (S202); determining, in a regional map, a local region map indicated by the region identifier information (S203); obtaining template environment information corresponding to at least one map position in the local region map (S204); and matching the current environment information with the template environment information to determine the position of the self-moving device in the local region map (S205). The region identifier information is identified when the self-moving device needs to be relocalized, and relocalization is performed by using the local region map indicated by the region identifier information, such that the efficiency of relocalization can be improved, and the problem of a complex relocalization mode for the self-moving device is solved.
