摘要

针对高速摄像条件下双目同步立体匹配存在困难的问题,提出了一种基于双目相机的空间直线运动轨迹快速测量算法。在建立了摄像机空间坐标系的基础上,基于小孔成像原理以及目标点与对应点的映射关系,构建了成像模型。对算法原理的实验验证表明,通过遍历点对组合并对其测量结果求平均值可减小误差,验证了原理的可行性与算法的有效性。

Abstract

Aiming at the difficulty of binocular synchronous stereo matching under high-speed camera conditions, a fast measurement algorithm for the spatial linear motion trajectory based on binocular camera is proposed. The camera space coordinate system is established ,and the imaging model is constructed based on the principle of small hole imaging and the mapping relationship between the target point and the corresponding point. The principle of the algorithm is verified experimentally, and the method of reducing the error by traversing the input points and finding the average value of the result is obtained. The feasibility of the principle and the effectiveness of the algorithm are verified.
