  • Publication number: 20250107681
    Abstract: 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 (S102); obtaining in real time image information of the obstacle in the driving path (S104); according to the position parameters and the image information, determining working area-based reference information of the obstacle (S106); and dividing the working area into a plurality of sub-areas on the basis of the reference information (S108). 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.
