METHOD FOR EXPANDING WORKING AREA BASED ON LASER MAP, CHIP AND ROBOT

The present disclosure provides a method for expanding a working area based on a laser map, a chip and a robot, and the method for expanding the working area includes using map pixel point information obtained by laser scanning to position pending boundary lines, deciding a next expansion of a rectangular working area according to an increment of a diagonal length of the rectangular working area framed by the pending boundary lines in a current expansion process, stopping expanding the rectangular working area of the robot when the increment of the diagonal length before expanding and after expanding reaches an overlap condition, which avoids a large connected area being dividing into a plurality of small areas in a process of dividing room areas, thus reducing working efficiency of the robot in indoor working areas. It is possible to save operation resources of the robot framing the working area, avoid using software resources to process framing and separating of corner areas of these isolated rooms, and there is no need to ensure that contour boundary positions of the working area framed on an indoor ground are all walls, thereby improving efficiency of the robot navigation along an edge.
