摘　　要：为了解决型材的自动检测问题,本文提出了采用激光三角测量进行自动检测的方法;通过线激光照射型材表面形成线轮廓,该线轮廓在相机中成像,再结合相机的标定参数以及线激光器和相机的相对坐标,利用摄影测量算法,计算出型材的高度轮廓线;最终设计出了一套可自动测量型材的外观轮廓尺寸的激光三角测量系统。In order to solve the problem of automatic detection of profiles, this paper proposes a method of automatic detection using laser triangulation;the line profile is formed by the line laser illuminating the profile surface, the line profile is imaged in the camera, combined with the camera calibration parameters and the line laser and the relative coordinates of the camera ,the profile are calculated using a photogrammetric algorithm;a laser triangulation system that automatically measures the profile size of the profile is finally designed.
