| 摘 要： | 异源图像匹配是视觉导航、多源图像融合分析的关键步骤之一。对于成像机理差别较大的异源图像,如SAR图像和可见光图像,采用传统的异源图像匹配算法难以得到满意结果。本文提出一种基于边缘相似性的异源图像匹配方法,首先分别提取待匹配图像的边缘特征点集;然后计算基准图的边缘距离场;最后基于边缘相似性模型,通过实时图边缘图和基准图边缘距离场计算边缘相似度,寻找相似度最大的变换参数即为最终匹配参数。采用SAR与可见光图对方法进行了测试,结果表明,这种方法能够快速可靠地实现异源图像匹配。

| Abstract: | Matching multi-sensor images is a key step in vision navigation and multi-sensor image fusion.However,the imaging mechanisms of SAR images and optical images are very different and it is difficult to match them using a conventional multi-sensor image matching algorithm.A new matching method based on edge similarity is proposed in this paper.With the method,edge maps are detected in reference image and real-time image separately.Then,the edge distance field of the reference image is calculated.Similarity mea... |
