摘　　要：提出一项利用真实月球探测数据来准确构建月球立体虚拟显示系统的技术,在双通道立体环幕投影系统上实现。利用嫦娥一号探月卫星的探月数据,采用多边形细分算法、自动拼接图像算法、渐进网格简化算法等多个关键技术构造具有真实立体感的3D月球模型,在VRP虚拟现实平台上进一步实现立体月球虚拟仿真系统,实现在月球表面的实时虚拟自动或交互漫游,戴上立体眼镜观察月球模型,使人具有身临其境的效果。该系统得到了精度更高的月球模型数据,解决了海量采集数据与实时显示的矛盾。通过该项技术可进一步了解月球表面的真实结构,为月球的科学研究提供基础,可应用于月球环境研究、虚拟漫游、月球科普宣传与展示以及其它月球虚拟现实相关的领域,具有广泛的市场前景。A technique was presented to build a stereo virtual display system of moon using real lunar exploration data, which was well implemented at a dual projective stereo system with annular screen. Based on the lunar exploration data derived from Chang^E-1, a couple of key techniques were employed, such as polygon subdivision algorithm, automatic seamless stitching method, progressive mesh simplification algorithm, to construct a realistic lunar model, from this a stereo display system of vir- tual moon was well designed and developed using VRP virtual reality software for automatic or interactive virtual tour in the lunar surface. People observed the lunar model by wearing stereoscopic glasses with immersive effect. In this system, more accurate lunar model data are obtained, the contradiction between massive data collection and real-time display is solved. The proposed technique is a fundamental work for further investigating the actual structure of lunar surface in lunar researches. With the great market potential, this technique can also be widely applied in kinds of areas such as research of lunar environment, virtual cruise, game development and other related applications.
