Title:
COORDINATE-BASED REPOSITIONING METHOD AND SYSTEM, AND CLEANING ROBOT
Document Type and Number:
WIPO Patent Application WO/2023/202256
Kind Code:
A1
Abstract:
A coordinate-based repositioning method and system (100), and a cleaning robot (10). The repositioning method comprises: obtaining a cleaning map having preset charging pile position information, and obtaining current charging pile position information in a current environment of an area to be cleaned (S100); detecting, according to the obtained current charging pile position information, whether the current charging pile position information matches the preset charging pile position information (S200); and when it is detected that the current charging pile position information matches the preset charging pile position information, determining that the coordinate-based repositioning of a cleaning robot (10) is successful (S300). The present invention solves the technical problem of a positioning error caused by too long matching time being consumed and mismatching being likely to be caused when the cleaning robot (10) performs re-positioning by means of whole-map image matching.
