用极线束约束方法进行图像匹配后的质量控制

Quality control after matching or image using constraint of epipolar line bunch

在立体视觉匹配过程中，不可避免的会出现大量的误匹配点。图像匹配后的质量控制是检测误匹 配点的基本方法。本文将对进一步提高匹配准确率进行探讨。基于连续性假设，在射影几何意义下，本文 利用一种外极线束和匹配点的整体信息，对相似性匹配结果进行检测，剔除其中的误匹配点。实验结果 证明，极线束约束具有较强的误匹配检测能力，大大提高了匹配准确度。

It is ineluctable in stereo vision that a large numbers of error matched pixel will be present. The quality control after matching is a general method for detecting error matched pixel. This paper described a method for further improving the veracity of matching. A constraint of epipolar line bunch based on Radial Geometry and continuity suppose was given to detect the similar matched pixel and weed out the error pixel by using correlative information of the pixel. The experiment proved that the constraint has better ability for weeding out error pixel. It increased the veracity of matching.
