摘　　要：从实际出发,考虑了火车轮对的检测是火车提速的瓶颈,现实检测自动化程度低,提出了利用图像处理技术和模式识别技术来检测轮对的方法。采用双CCD测量方法,解决了大视场测量问题的难度,降低了检测成本,提高了测量精度。本文从测量原理、标定方法和误差分析具体阐述了双CCD轮对测量系统。From starting off the practice, thinking about of the train wheel sets detecting is a bottle- neck of the speedup, while re- cently, the detecting is very low in automated degree, a kind of detection method base on image stitching and a technique of pattern recognition is put forward. Using of double CCD, resolve the problem of large- field detecting, reduce the detecting cost, enhance the measurement precision. This letterpress expound the image detecting system of wheel sets with double CCD from the theory of mea- surement, the method of demarcate and analyze of error.
