    • A method and apparatus for generating views of an environment with proper perspective and parallax. This invention captures panoramic views at many points in the environment, preferably by using fisheye lenses with subhemispherical fields of views to yield overlapping fisheye images that are seemed together, and stores them as planar polygons, which have been extended to include imagery occluded at their viewing position but visible at nearby points. Three-dimensional information on the environmental source of these polygons is determined and stored, enabling the playback system to simulate parallax as well as to produce stereographic images. Given a location and orientation in the environment, the playback system finds a nearby capture point and translates the polygons at that point to the specified location, producing an image. It then rotates that image to the desired orientation which it then displays.
    • 一种用于产生具有适当透视和视差的环境视图的方法和装置。 本发明在环境中的许多点捕获全景,优选地通过使用具有亚视场视野的鱼眼镜头产生似乎在一起的重叠鱼眼图像,并且将它们存储为平面多边形,其被扩展为包括在其观看时封闭的图像 位置,但在附近点可见。 确定并存储关于这些多边形的环境源的三维信息,使得播放系统能够模拟视差以及产生立体图像。 给定环境中的位置和方位,播放系统找到附近的捕获点,并将该点处的多边形转换到指定的位置,从而产生图像。 然后将该图像旋转到所需的方向,然后显示它。
