基于地形辅助导航系统之一的地形轮廓匹配系统,采用了基于Hausdorff距离和均方差的地形匹配算法,将实时飞行路线的地形数据和此路线两侧的地形数据与参考地形图上相应的地形数据匹配,在粗配和精配之后,输出匹配路线在参考地形图上的坐标信息.在FPGA开发平台上,用基于NiosII处理器的SOPC系统地形匹配模型获得了较高的地形匹配速度和精度.

Based on terrain contour matching system, which is one kind of TANS, this paper chooses Hausdorff distance and MSD algorithm as terrain matching algorithm. The terrain data in real-time flight path and its both sides will take part in terrain matching and after first and second matching, the matching result will come out, which is the coordinate of matching line. Based on SOPC with Nios II processor, this terrain matching model will run on FPGA development platform. It has a faster speed and higher accuracy.
