WIPO Patent Application WO/2022/160232
Kind Code:
A1
Abstract:
A detection method and apparatus, and a vehicle. The method comprises: after obtaining images collected by a plurality of cameras, converting images collected at the same moment into IPM images; then, cutting out each object in the converted IPM images by means of semantic cutting technology, so as to obtain a pixel block corresponding to each object; and finally, detecting a boundary, which is in contact with the ground, in each pixel block, so as to calculate, according to the detected boundary, the distance between a vehicle and the object corresponding to each pixel block. Compared with other sensors such as an ultrasonic radar and a laser radar, a measured distance value is more accurate.
