Title:
FUSED POSITIONING METHOD AND MOBILE ROBOT
Document Type and Number:
WIPO Patent Application WO/2022/116657
Kind Code:
A1
Abstract:
A fused positioning method and a mobile robot. The fused positioning method comprises: controlling a camera of a mobile robot to acquire image information for visual positioning; controlling a fan-shaped distance sensor (103) of the mobile robot to acquire distance information from the inside of a spherical pyramidal sensing area at a front end thereof (S501), and then supplementarily fusing a visual positioning result of the image information acquired by the camera and the distance information acquired by the fan-shaped distance sensor (103) to reduce positioning blind areas; wherein the fan-shaped distance sensor (103) is mounted at the front end of the mobile robot, and the camera is also mounted on the surface of the mobile robot, but the probe orientation of the fan-shaped distance sensor (103) is different from the orientation of the camera. The distance information covered by the non-rotary fan-shaped distance sensor (103) is used to be fused with conventional visual image positioning information, to compensate for positioning blind areas for each other on the same map, thereby describing the complete environment information.
