摘　　要：介绍了为2010年上海世博会设计实现的全球对地观测三维可视化系统。以球体屏幕几何校正技术为研究核心,基于中国气象局近期在探测资料分析方面的研究成果,在国内首次研制了全球资料球幕投影系统。系统建立了球幕投影的软硬件平台,研究实现了可以在球幕上动态显示包括大气、陆地、海洋等多种观测和模拟资料的图像处理技术,研制了无缝隙、标准化、覆盖全球显示的投影图像。系统软件基于Windows平台,可以多线程执行,实现数据处理的后台运行,辅以简便的控制界面,实现图像在球幕上的快速无延迟显示。系统可以帮助人们从太空的角度形象地了解地球和人类的生活环境。This paper described the design and realization of the global earth observation visualization system（GEOVS） which was developed for the 2010 Shanghai World Expo.To take the geometric correction technology of the sphere screen as the key research,the GEOVS was first developed based on recent related research results in data analysis of CMA.In this system,developed and established the hardware and software platform of the sphere screen projection,achieved the image processing technology which could display dynamic screen including atmosphere,land,marine and other observations and simulated data,and also developed the seamless,standardized,world projected images for this visualization system.The software system was based on Windows platform,multi-threaded execution,and data processing background,combined with simple control interface,to achieve the image quickly on the sphere screen display without delay.The system can help people from the perspective of the image space about our planet and living environment.
