| Abstract: | Considering the background of the testing system of vehicle-body dimensions, the paper developed a testing system of vehlcle-body dimensions based on computer vision according to binocular stereo vision theory. The testing principle and sensor model are expounded, and the point is also focused on the techniques of vehicle-body detection of difference and feature extraction using technique of improved Sobel algorithm,threshold segmentation, etc. Stereo matching is realized with the combination of feature matching and area matching. The testing results show that the testing system achieves automatic, fast and accurate testing of vehicle dimensions. |
