摘　　要：获取实物轮廓的特征参数是近些年来基于工业CT的逆向工程领域研究的重点之一,为了达到这一目的,本文改进了ICT图像的轮廓跟踪算法,准确快速地提取出实物的轮廓信息,并与矢量化技术相结合,完成实物任意位置任意方向切片轮廓的几何特征识别,实现了二维轮廓尺寸的参数化,最终集成一套专用的算法软件系统。Recently,one of research emphases in Reverse Engineering field based on Industrial Computerized Tomography is to obtain the characteristic parameters of an object’s contours.In this article,we improve the track algorithm of ICT contours for extracting the object’s contours rapidly and precisely,and then use vectorization technology to accomplish the geometrical characteristic recognition of 2D contours at any position or any direction from the CT images,and obtain the geometrical parameters of the contours at the same time.These algorithms are integrated into a specialized and practical Reverse Engineering software system.
