一、前言用光学方法测量工件直径的优点是可以用于非接触的在线测量,与微机处理结合能够提高精度。目前光学器件的发展增进了这种可能性。本文探讨的是利用 CCD 测量直径的可能性。其方法是用一个简单的相机,将 CCD 装在 I. INTRODUCTION The advantage of using optical methods to measure the diameter of a workpiece is that it can be used for non-contact on-line measurement and that the combination with a microcomputer can improve the accuracy. The current development of optics enhances this possibility. This article explores the possibility of using CCDs to measure diameters. The method is to use a simple camera, CCD mounted
