Binocular Stereo Matching Robust Algorithm Based on Energy of Marked Points
摘要
为提高双目立体视觉测量图像精确匹配的稳定性,提出一种基于特征点能量的稳健匹配新算法。该算法基于极线约束获取左右图像中特征点的初始匹配,根据特征点之间极线约束关系定义了一种不受仿射变换影响的能量来描述特征点,通过比对特征点能量值来剔除误匹配。该算法有效降低了误匹配率和误剔除率,从而满足多视角测量数据拼合过程中严格限制误匹配率的要求。实验结果表明,该算法正确匹配率大于95%,误剔除率小于2%,具有较强的稳健性。
Abstract
In order to improve the stability of the binocular stereo vision measuring accuracy image matching. A new robust matching algorithm based on feature point energy is proposed, the algorithm based on epipolar constraint to get the initial matching feature points around image. The energy not affected by affine transformation is defined to describe feature points based on epipolar constraint relationship among feature points, and the error matching is removed by comparing the energy of feature points. The proposed method effectively reduces the false matching rate and the false rejected rate so that it can meet the need of strictly limited false matching rate in the process of multiple angle measurement data. Experimental results show that the correct matching rate of the proposed algorithm is over 95%, and the false rejected rate is less than 2%.The algorithm has better robustness.
