摘　　要：激光三角法测量原理是目前光学测量应用最广泛的方法之一。其原理是光源发生器发出结构光光源(一般为激光点光源)到被测工件的表面,通过光学系统成像到线阵CCD或面阵CCD上的位置,由几何三角关系,从像点在CCD上的位置即可计算得到工件的高度尺寸,再通过测量系统的测量运动(即扫描运动)得到工件的全部外形尺寸。着重介绍热态成品车轮激光检测装置的结构配置及其完成的主要功能。Laser trigonometry measurement principle is one of the most widely - used methods in the optical measurement area. Its principle is structure light source of a light source generator （ usually laser point source） is onto the work piece＇s surface, through the optical system images onto the location of line array CCD or CCD array, the height size of the work piece can be calculated from the image point of the CCD position, through geometry of triangle relationship, and all dimension of workpiece can be obtained through measuring motion （i. e. scmaning movement）. Structure configuration and the main functions of hot railway wheels laser detection device are introduced emphatically.
