Title:
OBSTACLE DISTANCE MEASUREMENT METHOD, MOBILE ROBOT, DEVICE AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/185250
Kind Code:
A1
Abstract:
An obstacle distance measurement method, a mobile robot, a device and a medium, relating to the technical field of computers. The method comprises: obtaining an image to be detected acquired by a monocular camera deployed on the mobile robot; detecting an obstacle contained in the image to be detected, and determining a target pixel point used for representing the position of the obstacle in the image to be detected; obtaining, by using the pixel coordinates of the target pixel point in the image to be detected and a preset coordinate transformation relationship, the space coordinates corresponding to the target pixel point, wherein the coordinate transformation relationship is: a transformation relationship between the coordinates in the image acquired by the monocular camera and the coordinates in a preset space coordinate system; and determining, on the basis the obtained space coordinates, the distance of the obstacle relative to the mobile robot. By applying the solution provided by embodiments of the present application, the efficiency of obtaining the distance between the obstacle and the mobile robot can be improved.
