Improved 3D Reconstruction Algorithm Based on 1D Phase-Only Correlation

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.
