介绍了汽车四轮定位主要参数及其意义，并建立了相关数学模型，论述了一种基于计算机视觉原理的四轮定位仪的工作原理，该方法为对安装在汽车车轮上的目标盘进行运动前后的拍摄，对所拍摄的图像进行处理和分析，提取目标盘上的特征点坐标，根据特征点位置在空间上的变化情况，计算车轮空间旋转向量，进而由该向量与空间坐标系的各夹角求出四轮定位参数。%This paper introduces the main wheel alignment parameters and their significance and sets up related mathematical model,then presents a measurement for wheel alignment parameters based on computer vision,This method is that we shoot pic-tures of plate before and after the car moves,then extract the special dots on the plate thought processing images and calculate the Three-D vector though the changes of special dots’s location,finally get the four-wheel alignment parameters.
