The Mathematical Morphologic Research in Diverging Curved Surface of 3D Surface Reconstruction
医学图像三维表面重建分叉曲面的数学形态学研究

In the medical 3D Reconstruction, 3D object surface is reconstructed, by making use of the traditional slice-based reconstruction method- Due to the still existing problems, such as contour pairing, diverging surface, contour pair patching, etc. In this paper, the new methods are proposed for the problem solving. The contour pairing is carried out with overlapping. The diverging curved surface is decomposed with mathematical morphology. The boundaries generated by the morphologic operation are that of the diverging surfaces. The middle layer generated by the lower layer and the upper layer is not to insert into the two layers but only to join in one of the two layer. The contour mosaic is patched with triangles to form the surface after the polygons are simplified. The triangles are constructed under the criterion of the shortest diagonal.
