| 摘 要： | 在图像匹配的基础上,采用曲面拟合法对变形前后的两幅图像进行亚像素特征点的匹配,由曲面拟合法测量出应变方向上的亚像素位移后,再按照网格法中的应变计算方法将位移转变成应变.实验结果证明了该算法的可行性. |
| 关 键 词： | 图像匹配 曲面拟合 亚像素 复杂变形 |

| Abstract: | Surface fitting method was used to matching sub-pixel feature points of two distorted images based on image matching.Sub-pixel strain displacement was measured through surface fitting method.A full surface deformation was calculated simply by traditional grid method.The experimental result verifies that the algorithm is feasible. |
| Keywords: | Image matching Surface fitting Sub-pixel Complex distortion |
