A new method based on 3D digital model is introduced for geometrical inspection of tread pattern. Firstly,the surface data of tread pattern are acquired through the measuring equipment of REVscan laser scanner. Then, the obtained data are compared in the software of Ceomagic Qualify,and the results of inspection could be shown in visualization intuitively. This research provides a convenient and swift method for inspection of tread pattern.%针对轮胎花纹的几何形状,提出基于3D数字化模型的检测方法.利用测量设备REVscan激光扫描仪获取轮胎花纹的表面数据,并利用Geomagic Qualify软件对获得的数据进行检测,检测结果以图文方式直观进行显示.该研究为轮胎花纹的检测提供了方便、快捷的方法.
