Summary: | PURPOSE: A sparse feature point based on warping, a stereo matching fusion method and a device thereof are provided to robustly generate disparity information through effective fusion of a sparse feature point based warping method and a stereo matching method. CONSTITUTION: A disparity extraction unit(320) extracts disparity of a stereo image using a parallax of a stereo image through a stereo image matching method. A reliability calculation unit(330) calculates the extracted NCC(Normalized Cross Correlation) value. A matching fusion unit(340) uses corresponding points in which the NCC value exceeds a specific threshold with a feature point corresponding points obtained through sparse feature matching as a control point of sparse feature point based warping. [Reference numerals] (310) Sparse feature matching unit; (320) Disparity extraction unit; (330) Reliability calculation unit; (340) Matching fusion unit; (350) Sparse feature point based warping unit |
