| 摘 要： | 工业CT扫描通常只能得到某一断面上的二维信息,不能得到被检测物的整体描述,技术人员只能根据获得的系列二维图像在人脑中综合复原为三维结构.因而人们希望能得到直观地、精确地展示被检测物体三维空间结构的ICT直观图像,能得到比二维图像更加丰富的信息.因此断层图像的三维重建在工业无损探伤、天体结构的观察及其它更广泛的领域有着极其重要的实用价值和研究意义.本文提出了一种基于边缘检测的按层剥离的算法,此算法是在二维图像上进行,然后再将分割后的序列图像再进行三维重建实现三维物体的按层剥离显示效果.

| Abstract: | Most of the traditional ICT(industrial computed tomography)facility can only get the 2D information which might be very limited to determine the perfect spatial location and the exact area of the details. Therefore, there is a need to reconstruct 3D images. In 3D reveal step, it has realized the peeled display, rotating and iso-surface display. An algorithm has been designed to peel off the outer layer of the 3D object that is rebuilt in Matlab. This algorithm is based on the edge detector. The reconstructed 3D object can be rotated and zoomed in a PC software system. |
