Cabinet door positioning method, system and robot

The invention discloses a cabinet door positioning method, a cabinet door positioning system and a robot. The method comprises the steps: the robot is enabled to scan a two-dimensional code label on acabinet door, and the pose of the robot is adjusted according to the position relation between a camera of the robot and the two-dimensional code label; when the error between the pose of the robot and the preset pose is within the preset range, the front-back distance of the robot relative to the cabinet door is adjusted; when the front-back distance of the robot relative to the cabinet door iswithin a preset distance range, the robot is controlled to carry out angle adjustment in the preset direction. Therefore, the robot accurately positions the cabinet door. When equipment in the equipment cabinet needs to be inspected and maintained, the robot determines a target equipment cabinet by scanning a two-dimensional code arranged on the equipment cabinet. After that, the pose and the front-back distance between th
