基于竞选算法的旋转图像匹配

Rotated Image Matching Based on Election Campaign Algorithm

图像匹配在导航和零件定位等领域具有十分重要的意义。由于在图像采集过程中拍摄角度的不同导致图像存在着变形,如旋转变形,使得匹配难度增加。传统的图像匹配方法已经难以满足这种旋转图像匹配的要求,为了解决此类旋转图像匹配问题,提出了一种用圆投影来简化匹配模型,以竞选算法为搜索策略的图像匹配算法,实验验证了该算法可以抗任意角度的旋转且能快速匹配图像。

Image matching plays an important role in navigation, positioning of parts fields, etc. There exist significant transformations of image because the camera in difference angles during the image acquisition process,such as rotation,the matching more difficult. The traditional image matching methods have been difficult to meet the requirements of this rotating image matching, in order to solve these problems to rotate the image matching, this article proposes a image matching method which uses circular projection to simplify the matching model, and use an election algorithm as the search strategy of image matching algorithm, it has been verified by ex-periment that this algorithm can resist rotation of any angle and can quickly match the image.
