基于机器视觉技术提出3D四轮定位仪参数检测过程中车身坐标系的建立方法,以及车辆定位参数求解的向量-平面数学模型,针对实际检测过程中存在运动偏差的问题提出运动补偿的解决方法,并推导了运动补偿方法的数学模型。通过真实车辆的测试试验,结果证明该检测方法的正确性和有效性,为改进或研发3D四轮定位仪提供了新的思路,同时也为基于机器视觉的无靶标四轮定位参数检测技术奠定了理论基础。
This article put forward a theory to establish the bodywork coordinate system and proposed a vector-plane mathematical model to obtain the alignment parameter values. A motion compensation solution was addressed to the deviation in motion detection process and its mathematical model was derived. At last, an experiment with a real car was carried out and the validity and effectiveness of the proposed method were proved. This method offers an innovative solution for developing 3D four-wheel alignment systems, and also provides a theoretical basis for research on non-calibration plates.
