摘要

Due to traditional four-wheel alignment measurement techniques have such problems as need for many sensors, complicated calibration, fussy operation, low speed of inspection and low accuracy etc. Based on computer vision, the mathematical model for vehicle four-wheel alignment is set up. By taking sequence images of the target board fixed on the wheel in motion and calculating homography matrices between the target board and its images and rotation matrices, the directional cosine of rotation axis is obtained and further more the wheel alignment parameters are solved. Finally, the effectiveness of the mathematical model is verified by experiment.
