| 摘 要： | 提出了一种基于行星探测巡视器地面图像和高分辨率卫星图像的可量测虚拟现实环境构建方法。根据巡视器在不同方位角、高度角获取的立体图像,经过圆柱投影、自动匹配和无缝拼接生成360°全景图像。同时开发了从全景图像到原始图像的反算功能,使用户可直接在全景图像上进行量测,从原始立体像对上得到三维地形信息。三维可量测全景图像与基于NASA的World Wind的星球浏览器进行无缝集成,为行星探测应用提供了可量测虚拟现实环境,实现了从垂直视角卫星图像到地面水平视角巡视器图像的一体化量测。

| Abstract: | This paper presents a method of constructing a measurable virtual reality environment based on rover panoramic images and orbital imagery. Ground panoramic images acquired by a rover at different azimuth and elevation angles are automatically registered, seamlessly mosaicked and projected onto a cylindrical surface. A specific function is developed for inverse calculation from the panorama back to the original images so that the 3D information associated with the original stereo images can be retrieved or computed. The three-dimensional measurable panorama is integrated into a globe viewer based on NASA World Wind to form a measurable virtual reality environment for planetary exploration applications, providing visualization and measuring capabil- ities from overhead view and horizontal view. |
