【摘要】：在全球资源日益紧张的背景下，越来越多的国家把目光从地球转向了月球，原因在于月球上有人类梦寐以求的丰富资源。我国的探月工程起步比较晚，但是在许多方面取得了不小的成就，包括在对嫦娥一号、嫦娥二号探测成果的有效管理与展示，但是嫦娥三号将搭载更多的载荷平台，，获取月球更丰富更复杂的数据，对这些数据的组织、管理和展示不同于以往的形式。为了更好地服务探月工程及其它应用项目，必须开发嫦娥三号卫星探月信息展示系统。本论文首先简述了开发嫦娥三号卫星探月信息展示系统的背景以及开发的必要性，并进行了系统需求分析，其次探讨了系统开发的关键技术：（1）实时地标绘制方法，对于实时地标绘制，提出了基于数据表分区，根据当前视口的坐标范围，调取相应的数据，时绘制地标；（2）全景照片浏览方法，对于全景照片浏览，探讨了采用球面作为全景照片漫游模型以及SlimDX纹理贴图的方法，利用SlimDX取景函数完成全景照片浏览，提出采用纹理预测和多线程的方法加载一定数量的纹理到内存中和采用图像放大与图像融合相结合的方法实现视点间的平滑过渡。最后以C#语言与SlimDXAPI，以Gaea Explorer2.0作为二次开发的基础平台，开发了嫦娥三号卫星探月信息展示系统，建立了月球三维展示场景。模拟结果表明，系统运行稳定良好、数据入库快捷；实现了快速实时的地标渲染；全景照片加载迅速，多视点漫游过渡平滑；探测进程仿真和月球车巡视仿真视觉效果逼真。整个系统达到了预期目的。
[Abstract]:In the context of increasing global resources , more and more countries have turned their eyes from the earth to the moon because of the abundant resources they have dreamed of on the moon . But in many ways , China ' s lunar exploration works have been relatively late . However , the Chang ' e three will carry more load platforms to acquire more complex data from the Moon , and the organization , management and display of these data are different from the previous forms . In order to better serve the lunar engineering and other applications , the Chang ' e Three - moon Information Display System must be developed . This paper first briefly introduces the background and the necessity of development of Chang ' e 3 satellite lunar exploration information display system , and then discusses the key technology of system development : ( 1 ) The method of real - time landmark drawing , the method of using spherical surface as panoramic photo roaming model and SlimDX texture mapping is proposed . The simulation results show that the system is stable in operation , fast in data warehousing , fast real - time landmark rendering is realized , panoramic photo loading is rapid , multi - viewpoint roaming transition is smooth , the simulation of detection process and the visual effect of rover patrol simulation are vivid . The whole system achieves the intended purpose .
