摘　　要：对基于单张二维图像重建三维模型问题进行深入研究,对目前使用的方法进行比较分析,提出了基于紧水平支集的SFS三维模型重建方法。首先改进了基于快速匹配算法求解的紧水平支集方法,以提高紧水平支集求解的精度和效率,并将此方法应用到求解SFS问题,提出基于水平集快速求解SFS问题的方法;接下来为解决SFS固有的凹凸二义性问题,基于分水岭的思想寻找凹凸分界线,以此确定产生凹凸二义性的区域用以进行重建;最后利用拓扑变换重构凹陷区域,得到正确的三维模型。Single two-dimensional image reconstruction of three-dimensional model based on the issue in-depth study of the methods currently used comparative analysis ,proposed a three-dimensional model based on SFS reconstruction tight hori-zontal branch set approach .First ,fast matching algorithm to improve the level of support set tight-based approach to im-prove the accuracy and efficiency of solving sets tight horizontal branch ,and this method is applied to solving the SFS problem ,fast level set based method for solving SFS problem ;followed to resolve the SFS bump inherent ambiguity prob-lem ,based on the idea of looking bump watershed boundary ,in order to determine the ambiguity produce uneven areas for redevelopment ;finally reconstructed using topological transformation recessed area ,to get the correct three-dimensional model .
