基于梯度不变的彩色图像宽基线立体匹配方法
A Stereo Matching Method for Color Image Wide Baseline Based on Gradient Invariant
摘要
Abstract
Stereo matching is one of key technologies for stereo vision,and is basis of 3D reconstruction. Propose a stereo matching meth-od for color image based on gradient invariant in certain photometric range. First,corner points are extracted using SUSAN operator,and photometric range is decided of color image with invariant gradient using physical properties of objects. Then the initial corresponding re-lationship is determined using Mahalanobis distance. Finally,the false matched points are eliminated by gradient disparity to resolve the correspondence problem of color image under wide baseline. The experiment results show the matching method has good effect for some color images within certain illumination range,and has theoretical and applied value for 3D reconstruction.关键词
