| 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S FS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S FS问题，提出基于水平集快速求解S FS问题的方法；接下来为解决S FS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。

| Abstract: | 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 . |
