基于断层数据的三维重构技术的研究

Research on the Technology of 3D Surface Reconstruction Based on Layer Data

由一序列的平面轮廓线重构三维形体有着广泛的应用,而重构中的定位、分支等关键问题的处理直接影响三维形体的精度和实用价值.对面绘制以及使用该方法时需要解决的分支问题、定位、光滑性和连续性等关键问题进行分析,并对分支和定位问题的解决方法进行改进,提出按照多轮廓线的周长比率将多分支问题转化若干个单分支问题来解决分支问题和质点对齐进行定位,从而提高了重构的精度.

Reconstruction of 3D object from a set of plane contours has been widely used.However,how to solve key problems such as orientation problem and multiple branching problem directly affects the accuracy and application value of 3D objectThis paper explores surface rendering of 3D reconstruction and key problems such as multiple branching problem,orientation problem,smoothness and continutity etc.that must be solved while using the method,and it also improves the method of how to resolve multiple branching problem and orientation problem ,and provides the method that changes multiple branching problem into some single branching problems according to the rate of perimeter of multiple contours and the method that makes alignment of mean point,which greatly improves the accuracy of 3D reconstruction
