摘要
为了扩大双目立体视觉的视场范围,提高双目立体匹配的速度和准确度,设计了一种双目全方位视觉传感器(ODVS)立体视觉成像系统,提出了一种基于竖直线的极线校正算法.将两个结构相同的ODVS以上下同轴同向的方式进行组合,得到全景立体视觉空间,分析了双目ODVS的成像特性,实现了一种无需任何专门的标定设备、仅利用场景中与ODVS成像平面垂直的竖直直线(如门框、窗框,墙角线等)来校正其极线的算法.实验结果表明,该算法对双目立体全景视觉成像系统是一种有效的极线校正方法.
In order to enlarge the view field of stereo vision and improve the matching speed and accuracy of the stereo vision in binocular omni-directional images,a new kind of binocular ODVS（Omni-directional Vision Sensor） vision system is designed and an epipolar rectification algorithm based on vertical lines is proposed.Firstly,we compose two ODVS with the same structure in the coaxial way and can get panoramic field of stereo vision space,then analyzes the imaging characteristics of the ODVS,proposes an epipolar rectification algorithm using vertical line（such as door frame,window frame,corner line and so on） which is perpendicular to the imaging plane in order to rectify the epipolar of the two omni-directional images.This epipolar rectification algorithm needs no any special calibration equipment.The experiments demonstrate that the algorithm is the validity and efficiency for the binocular ODVS vision system.
