Measuring Technique for Vehicle Four-Wheel Alignment Parameters

汽车四轮定位参数是影响汽车操纵稳定性与前轮异常磨耗的重要因素,传统的四轮定位技术已经不能满足现代汽车四轮定位参数测量的实时、在线、快速的要求,基于计算机视觉的新一代四轮定位技术具有非接触、实时、在线、快速、精度高的特点,全球最新的基于计算机视觉的V3D三维成像技术代表了四轮定位参数测量技术的最新方向,本文详细介绍和分析了汽车四轮定位参数测量技术的研究状况和最新进展。

Vehicle four-wheel alignment parameters are important factors which affect handling stability and abnormal wear of tires. Traditional four-wheel alignment technique can not meet the needs of real-time, on-line and fast measurement for modern vehicles. The new four-wheel alignment technique based on computer vision is a non-contacted, real-time, on-line, fast and high-accuracy method. V3D technology, also based on computer vision, represents the most advanced measuring technique of four-wheel alignment parameters in the world. The present research and new progress on four-wheel alignment are introduced and analyzed in detail in this paper.
