Method and Apparatus for Constructing Map of Working Region for Robot, Robot, and Medium

A robot ( 100 ) working area map construction method and apparatus, a robot ( 100 ), and a medium, wherein the robot ( 100 ) working area map construction method comprises scanning in real time an obstacle in a driving path and recording position parameters of the obstacle (S 102 ); obtaining in real time image information of the obstacle in the driving path (S 104 ); according to the position parameters and the image information, determining working area-based reference information of the obstacle (S 106 ); and dividing the working area into a plurality of sub-areas on the basis of the reference information (S 108 ). By means of radar scanning and image capture by a camera for double insurance, the robot ( 100 ) working area map construction method significantly improves recognition accuracy for room doors and avoids room division confusion caused by the incorrect recognition of doors.
