Abstract:
To the situation that the measuring method currently used is unable to realize the accuracy and efficient detection, the fast detection system adopts monocular vision is proposed for testing the difference of automobile wheelbase. Based on the spatial alternation theory of word coordinate and computer image coordinate, the measuring model for the ground marks of vehicular wheels based on camera system of monocular vision is constructed, which realizes the precise camera calibration. For the accuracy recognition of ground marks, according to the analysis and comparison of various image processing methods, the recognition strategy for the center of the wheel ground mark based on Canny detector and morphologic manipulation is determined. The hardware and software of the testing system of axle distance is designed. The experiments show that the detection system achieves the requirement of realtime test and the precision is 1.0 mm. 1 tab, 7 figs, 15 refs.
