摘要 视觉是人类获取周围环境信息的重要手段,当用双眼去观察不同物体的时候,会有远近之分。双目立体视觉系统就是仿照人的双眼去感知距离,具体实现过程如下:双目视觉系统的摄像机标定、双目摄像机同时获取图像、图像预处理、特征点提取、特征点匹配和空间坐标计算。本文从双目视觉系统的原理出发,推导了双目视觉系统的数学表达式,分析了几种不同的特征点提取方法,提出了F-HARRIS方法,提高了计算效率,利用双向交叉匹配办法匹配特征点,在利用几何约束,剔除误匹配点,原理简单易懂,效果比较理想。试验中采用畸变效应小的摄像机(即不考虑畸变),且摄像机已做过标定;图像预处理就是一些简单的平滑滤波;图像分辨率为2048*1536。
