摘　　要：用图像的三维重建技术,实现连续断层CT图像的三维可视化是近年来国内工业CT领域内的一个重要研究方向。用三角面片连接轮廓线方法,实现了连续等间隔工业CT图像的三维重建,获得了扫描物体的三维立体显示图像。通过计算机交互操作,实现多角度、多方位观察物体,无损测量物体三维参数等功能。利用重建出的三维图像,检测人员可以获得物体更多的空间结构信息,从而提高无损检测的方便性和准确性。It＇s an important research aspect in domestic ICT field, that the 3-D visualization of continuous ICT images reconstructed by 3-D reconstruction technology. The contour lines are joint by triangles in the course of 3-D reconstructions of the continuous equidistant ICT images. After the stereo images of the scanned objects are displayed, some special functions including inspections of the objects from different angles and orientations, nondestructive measurement of some 3-D parameters and so on will be carried out just by operating the computer. The inspectors can get more detailed structural information by the reconstructed images. So in this way the convenience and veracity of the non-detection have been promoted
