摘　　要：对某工业CT机提供的序列断层图像利用Matlab功能强大的函数进行三维重建,通过设计算法自动选取阈值将各层二维图像外层物质灰度值置为背景色,再将其进行三维重建,从而实现剥离显示,效果较好,可推广到多层环状物质的剥离中去。The method for three dimensional(3D) reconstruction of industrial computed tomographic(ICT) images was researched. An algorithm was designed for peeling off the outer layer of the 2D object and rebuilding by Matlab. Testing result was good and the method could be applied to the peel display of multilayer object.
