基于工业CT切片数据的CAD模型重构

为了使工业CT（computed tomography）扫描获得的切片数据能够被CAD软件直接处理并进行模型重构，在得到切片轮廓点坐标数据的基础上，提出了用IGES（Initial Graphics Exchange Specification）格式作为边缘轮廓坐标数据和CAD软件交换标准的方法，并采用VC^＋＋设计了IGES格式转换软件。实现了IGES格式文件的生成，并用逆向软件Imageware重构出三维CAD模型，取得了较好的效果。

The CAD Model Reconstruction Based on ICT Slicing Data

To make the slice data of industrial CT can be processed directly with CAD software and the model be reconstructed, based on the contour data,one method is put forward which adopting IGES(Initial Graphics Exchange Specification) as the transform standard between the contour data and CAD software . The IGES data transform software is designed with VC ++ . The IGES file is got and the 3D CAD model is reconstructed in Imageware. The result is good.
