摘要

本文基于双目视觉图像传输系统重点研究了摄像机标定与立体匹配两个模块。在摄像机标定中,重点阐述了三大坐标系、两种摄像机模型以及张正友平面标定法,基于Matlab实现了立体标定过程并对实验结果进行了分析;在立体标定中,重点阐述了基于全局误差能量最小化立体匹配算法和基于线性生长立体匹配算法的原理,基于Matlab仿真了立体匹配算法的实现过程,并就可靠度与计算量两个指标对两种匹配算法进行了比较分析。

Abstract

Binocular vision image transmission system design

Abstract

Based on the binocular visual image transmission system, this paper focuses on the camera calibration and stereo matching .In the camera calibration, this study was expounded the three coordinates, the two kinds of camera models and ilf plane calibration method, camera calibration was implemented based on Matlab and the experiment results are analyzed; In stereo calibration, this study was expounded the principle of stereo matching algorithm based the global error energy minimization and stereo matching algorithm based on linear growth, and the implementation process of the stereo matching algorithm based on Matlab, and the reliability and the amount of calculation of two indicators of the two matching algorithms are analyzed in comparison.
