一种基于左右视线的立体图像匹配算法

提出了一种有效提高立体匹配中遮挡和低纹理区域匹配精度的方法,算法充分利用立体视觉中的全局约束条件,对不同区域采用不同的约束条件和强度来获得高可靠性点的视差,并且引入左右视线的概念,用于解决复杂场景情况下的左右视图的匹配问题。同时采用改进的协同算法(cooperative algorithm,CA),在视差梯度的约束下,对高可靠性点的视差进行逐步地扩散,最终得到致密的视差图。实验仿真表明,方法可以有效地提高遮挡和低纹理区域中的匹配精度,从而产生较精确的致密视差图。

A Stereo Matching Algorithm Based on Left and Right Views

An algorithm that improves the matched precision of occlude and textureless region is presented.By using the global constraint conditions,the uniqueness and the order constraint,high credible parallax is obtained from different regions under different constraint condition and intensities so as to solve matching of left and right views from the complicated scenes.Under the constraint of the gradient of parallax,the improved cooperative algorithm is applied to pervade the of the point which has high reliabili...
