多视重建的研究现状

：对目前的多视重建技术进行了综述．先介绍了多视重建的分类和评价方法，然后分析了光照一致性约束和可见性约束，再分别讨论了几个有代表性的算法，如深度图方法、空间雕刻法、变形模型方法、目标函数求解法（包括水平集法、图割法）、种子生长法、概率估算法（马尔可夫场方法、EM 方法）等等，再探讨了这些算法的不足之处．最后，提出了融合多种方法、多种线索的3 维重建新思路，以提高多视重建的完整性和精度．

A Review of Today's Multi-view Reconstruction

This paper reviews today’s algorithms about multi-view reconstruction. Firstly, the classification and evaluationmethods for multi-view reconstruction are introduced. Secondly, some constraints, such as photo-consistency and visibility,are analyzed. Then, some typical algorithms are discussed, such as depth map, space carving, deformable model, objectivefunction optimization (including the level set method, graph cuts method), seed-growing method, and probability estimationmethod (including Markov-field method, EM method). Some shortcomings in all of these algorithms are discussed. A new3D reconstruction idea integrating some of aforementioned reconstruction methods and reconstruction cues is proposed toimprove the integrity and accuracy of multi-view reconstruction.
