摘　　要：鉴于传统的四轮定位技术存在需要的传感器众多、标定复杂、操作繁琐以及检测速度慢、精度不高等问题,应用计算机视觉理论建立了一种四轮定位参数检测数学模型,重点阐述了对该模型进行求解的过程,并根据所建数学模型及实车检测实验给出了测量方法和步骤。实验结果表明,所提出的模型及方法是正确和有效的。In view of the problems of the need of multiple sensors, complexity in calibration, over-elaboration in operation, low speed of measurement, and poor accuracy in traditional four-wheel alignment measurement technique, a mathematical model for vehicle four-wheel alignment parameters measurement is established based on computer vision. The solving process for the model is emphatically expatiated with measurement method and procedures for real vehicle inspection given. The results show that the proposed model and method are correct and effective.
