基于扩展相位相关的小基高比立体匹配方法
A Small Baseline Stereo Matching Method Based on Extended Phase Correlation
摘要
Abstract
A small baseline stereo matching method based on extended phase correlation is proposed to obtain high precision sub-pixel disparity for small baseline photogrammetry.The multi-step strategy is adopted in this method.Firstly,the integer pixel disparity is calculated by an adaptive support window local matching method.Then the relationship of corresponding points is established under the guidance of integer pixel disparity.The sub images are extracted through selecting the corresponding points as the center.Finally,the sub-pixel disparity is obtained by matching the sub images utilizing an extended phase correlation matching method.The experiments are carried out by using the small baseline stereo image pair and artificial synthesis stereo image pair with sub-pixel disparity,the results show that the small baseline stereo matching method based on extended phase correlation has superior performance on precision and efficiency.关键词
