摘要 在T Shibahara等提出的基于一维相位相关的三维重建算法的基础上进行改进,对图像序列进行加窗前处理;在均值法中对图像序列进行有效的加权处理;利用各匹配等级之间的相关性优化由粗到精的立体匹配结构;对三维模型进行限制深度的后处理.实验结果表明,本文提出的改进算法在保证输出三维模型精度的基础上比原始算法的三维重建效率有明显提升. T Shibahara et al proposed a high-accuracy stereo correspondence technique based on 1D Phase-Only Correlation.In this paper,we propose four improvements as follows:windowing to reduce boundary effects;weighting in averaging 1D POC functions;optimizing the coarse-to-fine matching;limiting the range of depth.Experimental results show that the 3D reconstruction efficiency is improved significantly compared to the original algorithm.
