摘要
提出一种基于金字塔Lucas-Kanade光流跟踪技术的变形位移测量算法.该算法通过检测变形前图像的角点,先利用金字塔Lucas-Kanade算法在变形图像中搜索其匹配点,再经计算求得变形位移值.实验结果表明,该算法进行变形位移测量时精度高、稳定性好.
A light flow deformation displacement measurement algorithm based on a pyramid Lucas-Kanade tracking technology was proposed. After the angular points of the image before the deformation were detected, then the pyramid Lucas-Kanade algorithm was used to search the matching points in the deformation image, and finally the deformation displacement value was calculated.The experimental results show that this algorithm has a high precision and good stability.
