摘要
单目视觉定位因其定位模型简单、标定步骤少等特点被广泛应用,根据灭点原理对单目视觉定位中的相机标定进行了研究和分析,并将RANSAC方法用于灭点计算来改善灭点的平稳性,提高了相机标定参数的精度。
Because of the briefness model and less step,Monocular Vision Localization is used extensive.We searched and analyzed the camera calibration of monocular vision localization according to the principle vanishing point.In addition,we advanced a new method for line grouping.And we used RANSAC method in calculating vanishing point to ameliorate stationary and improved the precision of camera calibration parameter.
