摘　　要：基于匹配识别的导航系统不能缺少匹配参考图的支持,制备前视匹配参考图更是前视目标匹配识别的一个关键环节。为了利用航空航天图象信息制备出有效的前视匹配识别所需的参考图,提出了基于3D可视化GIS的前视参考图生成方法,介绍了该方法总体思路,分析了其中的三维数据制备、目标区三维场景生成和前视匹配序列参考图生成等关键环节,给出了部分制备的参考图与实时图的匹配实验结果。实验结果表明,利用这种方法制备的前视参考图可以满足前视匹配识别的需求。The scene matching aided navigation system can＇ t run short of reference map. Preparing forward looking reference map is also very important in the forward looking recognition system. To preparing forward looking reference map by aerospace image information, a method based on 3D visualization GIS is developed in this paper, it also introduces the base idea of this method, explains how to prepare the 3D data, how to create the 3D scene of target area and how to get the serial forward looking reference map. According to the experimental result, the forward looking reference map prepared by this method is excellently.
