Document Type and Number:
WIPO Patent Application WO/2022/095170
Kind Code:
A1
Abstract:
An obstacle recognition method and apparatus, and a device, a medium and a weeding robot. The method comprises: according to color information of a candidate weeding area image, determining a candidate obstacle area in the candidate weeding area image (110); acquiring contour information of the candidate obstacle area, wherein the contour information comprises chrominance information, range information and roughness information (120); and according to a preset contour information determination condition and the contour information, determining whether there is an obstacle in the candidate weeding area image (130). By means of the method, the problems in the prior art of a large amount of manpower and materials being consumed and the costs increasing caused by the boundary of a weeding area of a weeding robot usually being calibrated by means of embedding boundary lines can be solved, and the problem in the prior art of the shape of the weeding area being limited to a certain extent due to the limitation on the embedding of the boundary lines can also be solved, thereby realizing the effect of improving the efficiency and accuracy of recognizing an obstacle in a candidate weeding area of the weeding robot.
