提出了一种结合仿射SIFT(Affine-SIFT)和仅相位相关(PoC)的高精度、高密度和鲁棒性的宽基线立体匹配方法。基于ASIFT的匹配对立体图像的透视变形具有较强的鲁棒性，而对应的点是稀疏的。基于PoC的匹配可以找到稠密的对应关系，而在宽基线立体声的情况下，对应点不可靠。ASIFT和POC的互补使用使得无论相机基线的长度如何都可以找到准确和密集的立体对应。通过一组实验，我们证明了该方法与传统方法相比具有更好的性能。并将该方法应用于多视点图像的三维重建。
This paper proposes an accurate, dense and robust wide-baseline stereo correspondence matching method combining ASIFT (Affine-SIFT) and POC (Phase-Only Correlation). ASIFT-based matching is robust against perspective deformation of the stereo images, while the corresponding points are sparse. POC-based matching can find dense correspondence, while the corresponding points are not reliable in the case of the wide-baseline stereo. The complementary use of ASIFT and POC makes it possible to find accurate and dense stereo correspondence regardless of the length of camera baseline. Through a set of experiments, we demonstrate that the proposed method exhibits efficient performance compared with the conventional methods. We also apply the proposed method to 3D reconstruction from multi-view images.
