    • A computer system generates a cylindrical environment map comprising a plurality of elements and associated information pertaining to images of a panoramic scene by storing in memory information associated with elements of a side image of the panoramic scene and information associated with elements of a top image and/or bottom image of the panoramic scene. For at least one element of the cylindrical environment map, if the element of the cylindrical environment map corresponds to an element of the side image, the information corresponding to the element of the side image is associated with the element of the cylindrical environment map. However, if the element of the cylindrical environment map corresponds to an element of the top image (or bottom image), the information corresponding to the element of the top image (or bottom image) is associated with the element of the cylindrical environment map. The information associated with elements of the side image, top image and/or bottom image may be color of the panoramic scene at the element, depth of the panoramic scene at the element, or an action related to the element. Also presented is a computer system that renders a view of such a cylindrical environment map for display.
    • 计算机系统通过存储与全景场景的侧面图像的元素相关联的存储器信息和与顶部图像的元素相关联的信息来生成包括与全景场景的图像有关的多个元素和相关信息的圆柱形环境地图和/ 或全景场景的底部图像。 对于圆柱形环境图的至少一个元素,如果圆柱形环境图的元素对应于侧面图像的元素,则与侧面图像的元素相对应的信息与圆柱形环境图的元素相关联。 然而,如果圆柱形环境图的元素对应于顶部图像(或底部图像)的元素,则与顶部图像(或底部图像)的元素相对应的信息与圆柱形环境图的元素相关联。 与侧面图像,顶部图像和/或底部图像的元素相关联的信息可以是元素处的全景场景的颜色,元素处的全景场景的深度或与元素相关的动作。 还提出了一种计算机系统,其呈现用于显示的这种圆柱形环境图的视图。
