摘　　要：根据实际检测中方便、快捷、直观的要求,通过CCD相机实时采集旋转平台上螺纹产品信息,通过数学计算进行坐标转换以及三维重建。此方法操作简单,检测精度高,能够检测出螺纹的大径、小径等参数。实验表明,通过标定后,测量的精度达到0.006mm,存在螺纹外观缺陷的产品可100%识别,其过判率小于0.1%。文中详细讲述了系统的构成。Thread is a kind of product most widely used in manufacturing. The quality of the thread directly affects the stability and the reliability of the products that use it. According to the actual testing require- ments of convenience, the paper put forward a method of threaded target 3 d reconstruction based on the single camera rotating platform. With its advantages of simple operation, high accuracy, this method can detect the parameters of major diameter and minor diameter. This paper describes the composition of the system, detection principle and the processing of PC data software in details.
