| 摘 要： | 目前锥束CT的三维重构主要采用面绘制，其方法有两类,即体素级重构和切片级重构。在对比两类方法的基础上，提出了一种新的二维切片轮廓重构与三维表面重构相结合的切片级重构方法，然后以标准MC算法和该算法分别对两个实例进行重构并比较。结果表明，该算法更适合工业产品的三维表面重构。

| Abstract: | Surface Rendering is the main method adopted in Cone Beam Computed Tomography for 3D surface reconstruction currently,and it includes two classes of methods: voxel-based reconstruction and slice-based reconstruction.In this paper,we compare the two methods and propose a new slice-based reconstruction algorithm based on 2D slice contour reconstruction and 3D surface reconstruction.Then we use of the standard MC algorithm and the new algorithm to reconstruct two instances respectively.The experiments show that slice-based reconstruction is more appropriate for the 3D reconstruction of industrial productions. |
