地图匹配制导由于具有良好的自主性而成为飞行器导航的一种重要方式。本文首先从飞行器导航的应用出发,对于可用于地图匹配制导的匹配方法的特点进行了分析;然后,提出了一种基于二值边缘新的匹配度量,并给出了基于距离变换的边缘二值图像匹配方法;通过采用航片与卫片、可见光图像与合成孔径雷达图像等所进行的大量实验,结果表明本文所提出的方法比常用的平均绝对算法和归一化互相关算法速度更快、匹配定位精度更高
Map matching guidance has become an important way of aircraft navigation due to its good autonomy. Based on the application of aircraft navigation system, this paper firstly analyzes the characteristics of the matching method which can be used in map matching guidance. Then, a new matching metric based on binary edge is proposed and the edge binary based on distance transform Image matching method. Through a large number of experiments using aerial photos and satellite photos, visible light images and synthetic aperture radar images, the results show that the proposed method is faster than the common average absolute algorithm and normalized cross-correlation algorithm, Match positioning accuracy higher
