Abstract

The invention belongs to the field of robot positioning, and discloses a robot and a positioning method and device thereof. The method comprises the steps of obtaining an infrared image of a scene where a robot is located; acquiring a two-dimensional code image included in the infrared image; matching the acquired two-dimensional code image with a two-dimensional code in a preset two-dimensional code map, and determining a two-dimensional code matched with the infrared two-dimensional code image in the two-dimensional code map; and determining the pose of the robot according to the matched two-dimensional code. Since the acquisition of the infrared image is generally not affected by strong light, weak light, no light or a scene with drastic change of illumination, the robot can accuratelyacquire the two-dimensional code image in the scene, thereby overcoming the influence of drastic change of illumination on the positioning precision, and ensuring the positioning precision of the robot in the scene with drastic change of illumination.

Description

technical field [0001] The present application belongs to the field of robot positioning, and in particular relates to a robot, and a positioning method and device for the robot in complex light and shadow environments. Background technique [0002] With the increase of robot application scenarios, new requirements are put forward for the positioning ability of robots. For example, when a robot used for stage performances is positioned, due to the drastic changes in the lighting on the stage, there are usually strong light, weak light, and sometimes no light. When the robot performs on the stage, the robot needs to be precisely positioned to ensure that the robot can successfully complete the stage performance. [0003] The current robot positioning methods include positioning methods based on WIFI, Bluetooth, UWB (ultra-wideband), laser radar or video. Among them, wireless positioning methods based on WIFI, Bluetooth, UWB (ultra-wideband) have low positioning accuracy and...
