| 摘 要： | 针对图像配准对时间和精度的需求,本文提出适用于角点特征的配准算法：提取两幅图像的角点构造三角形,计算三角形的角度,寻找两幅图像对应的相似三角形,用三角形的顶点坐标求得仿射变换系数,参考图像进行仿射变换,与待配准图像比较相似性,最大相似性对应的变换图像为配准结果。引入强角点和Harris角点对该算法进行验证。与Fourier-Mellin和基于RANSAC寻找匹配点对角点配准算法比较,实验数据表明该算法的快速准确,并具有一定的抗噪性。 |
| 关 键 词： | 图像配准 点特征 角点 仿射变换 相似三角形 |

| Abstract: | For the need in time and precision of registration,the article advanced an algorithm based on corner feature that satisfied this need well.Extracted corners in both two images,constructed triangles using these corners,found the similar triangles by computing the angles of each triangle in two images and got the affine transformation coefficients by using the coordinates of six vertexes of two similar triangles in two images.Transformed the reference image using the affine transformation coefficients,compare... |
