基于计算机视觉的汽车四轮定位技术研究

基于计算机视觉技术的四轮定位仪可实现汽车车轮定位参数的简单、快速、精确检测,具有良好的应用前景.该产品目前主要依赖进口,对其原理国外厂商严格保密,国内文献尚未见详细述及.本文对基于计算机视觉的车轮定位参数测量原理进行了探讨,分别对国外基于透视学的方式和本文基于空间向量的方式进行了详细分析,给出了基于空间向量方式的数学模型,并进行了现场实车检测实验,结果表明了本文所提出的模型是正确有效的.为国内汽车电子检测行业的发展提供了新技术.

Study of wheel alignment based on computer vision

The four-wheel alignment instruments,which adopt computer vision technique,can realize easy,fast and exact alignment measurement.The product mostly depends on importation.Its principle is kept secret in foreign and hasn't been discussed closely in home.This article studies the measuring principle and discusses it particularly in space vector method and our perspective method.Mathematic model for space vector method is also proposed.Field vehicle experimental results show that the proposed model is effective and correct.And the development of home automobile inspection can be promoted.
