摘要
通过对月球形貌可视化技术的研究,分析了利用嫦娥一号获取的月球地形和正射影像数据制作月球形貌图的技术方法.重点介绍了广泛应用于嫦娥一号数据处理和分析的晕渲地形图制作、月球地形影像假彩色融合和三维形貌场景构建的原理,并给出了每种方法的应用实例.这些方法为后续月球探测研究、月球空间信息系统以及"数字月球"的建设奠定了基础.
The Chang＇E-1 is the first Chinese lunar explorer.One of the major objectives of the mission is to obtain photographic and topographic data of the moon.Based on these data,applications of the visualization of lunar surface are discussed in this paper.The methods to develop lunar topographic map from Chinese Chang＇E-1 lunar data are introduced.The methods include colorcoded shaded relief mapping,3D modeling and data fusion.The software for shaded relief mapping is presented and briefly compared.And the construction of 3D topographic model is discussed.Then, data fusion theories are summarized.And procedures of image fusion based on HIS transformation are applied in lunar visualization.The examples using lunar data obtained by Chang＇E-1 were shown in each section of the methods explanation.In the end,the future of lunar visualization is anticipated.
