摘　　要：介绍了一种针对运行列车基于激光三角法原理的轮对参数在线自动检测系统,论述了其测量原理和工作方法。该方法是将线激光器和摄像机分布在钢轨的内外两侧,线激光器投射到车轮的踏面上,外时钟同步触发摄像机,获取车轮截面轮廓图像,采用基于平面靶标的方法实现CCD摄像机的标定,通过坐标变换,求解算出轮对的各个参数。实测表明,该系统可完成运行列车轮对参数的自动测量。In view of a running wain base on the principle of laser trigonometry round of online Automatic Testing System wheel set parameters, The principle of measurement is discussed and methods of work. The laser lines and cameras will be outside the rail, the lines of laser projection the wheel surface, External Clock trigger the camera to obtain images wheel profiles.Plane target is based on a CCD camera calibration method, to coordinate The results show that the system can complete the operation of the trains round the automatic measurement parameters.
