Abstract

The invention discloses a map processing method, an electronic device and a computer-readable storage medium. The method extracts obstacle image information from the map and stores it in the first map image, and extracts non-obstacle image information and stores it in the second map image; iteratively acquires the outline points of each non-obstacle in the second map image in the The closest position point of the obstacle within the preset search distance of the corresponding position in the first map image is used as the obstacle contour position point, and it is added to the output map, which can further perform the second step on the obstacle contour Confirmation makes the map more accurate; in the output map image, the obstacle and non-obstacle areas are close to each other, and the obstacle only retains the obstacle boundary close to the non-obstacle area, making the map more concise and the lines smoother.

Description

technical field [0001] The present invention relates to the field of robot automatic control, in particular to a map processing method, a mobile robot and a computer-readable storage medium. Background technique [0002] At present, in mobile robots, such as sweeping robots, mapping and navigation are the key technologies to realize their mobile functions. The mobile robot mainly builds an obstacle map for navigation based on the environmental information measured by distance sensors, image sensors, etc., and at the same time, the map can be displayed on the terminal to allow users to observe its working status. After the map is constructed, the preliminary map needs to be further processed before it can be displayed. The simple thresholding process makes the obstacles discontinuous and the wall thickness too large. [0003] In addition, when the mobile robot displays the map on the terminal communicating with the mobile robot, the shape of the obstacle will be excessively ...
