摘要： 提出了一种基于图像区域特征的模糊熵差景像匹配新算法。针对两幅不同时相图像,该方法先进行区域特征提取,然后通过构造模糊熵差匹配度量函数来实现图像的自动匹配。与传统的算法相比,该算法具有明显的抗几何失真和高斯噪声的能力,且实时性也较好,为飞行器实时景像匹配提供了一种可行方法。

Abstract: A scene matching algorithm based on feature extration is discussed in this paper.Before adopting a fuzzy entropy similarity metric,edge detection,image segmentation and segmentation description are accomplished.Compared with conventional methods,results show that the proposed method has advantages of fast and high ability of antijamming,and can be used for the real time positioning of aerocraft.
