一种改进的快速立体匹配方法

A Improved fast Stereo Matching Method

首先介绍了立体匹配的一般步骤,再考虑到立体匹配的实时性,从众多立体匹配算法中选择了基于区域的WTA相关匹配算法。同时,为了保证匹配的正确性,降低误匹配率,本文在立体匹配中采用了亚像素插值和边缘检测等多项改进措施。实验结果表明,本文的立体匹配算法既具有良好的实时性也具有较高的精度,完全能满足移动机器人双目立体视觉等应用要求。

This paper first introduces the general steps of stereo matching,then considers the real-time of stereo matching,and chooses the WTA stereo matching algorithms based on region from many stereo matching algorithms.This paper adopts some improving measures such as subpixel interpolation and edge detection to ensure the conrectness of matching and decrease the percentage of bad matching meanwhile.The experiments prove that this paper’s stereo matching algorithms have good real-time performance and better precision,and can meet the requirements such as binocular stereo vision applications of mobile robot.
