大尺寸弧长图像测量系统及其图像处理方法的研究

Study on the large size arc length image measuring sys- tem and its image processing methods

基于ＣＣＤ图像测量技术，提出一种新的非接触大尺寸弧长图像测量系统，该系统可用于测量封闭或非封闭、规则或不规则轮廓的大尺寸弧长。文中给出了系统的结构及原理，并着重讨论了该系统的图像处理方法。最后，利用新系统进行了现场比对实验。

On the basis of CCD image measuring technology, this paper proposes a new kind of large size arc length non-contact image measuring system, which can be used to measure large size arc length of closed of non-clsed and regular or irregular objects. The constructure and principle of the new system is stated and image processing methods are especially researched. In the last, comparison experiments in situ are done.
