Pyramid stereo matching for spherical panoramas
Jian Weng, Wei Zhang, Weidong Zhang, Jianjie Gao · 2016
This paper presents a novel pyramid stereo matching method to improve the matching accuracy of panoramas. Initial camera parameters and feature correspondences are obtained from Structure From Motion (SFM) with normal images extracted from two panoramas. Then a stereo matching pyramid is constructed to refine the feature correspondences layer by layer, and the correspondence is corrected in the original panoramas. Experimental results show the matching accuracy gains provided by the proposed approach.
