In this paper, we propose to work in the 2.5D space of the scene to facilitate composition of new spherical panoramas. For adding depths to spherical panoramas, we extend an existing method that was designed to estimate relative depths from a single perspective image through user interaction. We analyze the difficulties to interactively provide such depth information for spherical panoramas, through three different types of presentation. Then, we propose a set of basic tools to interactively manage the relative depths of the panoramas in order to obtain a composition in a very simple way. We conclude that the relative depths obtained by the extended depth estimation method are enough for the purpose of compositing new photorealistic panoramas through a few elementary editing tools.

在本文中，我们建议在场景的 2.5D 空间中工作，以促进新的球形全景图的合成。为了向球形全景图添加深度，我们扩展了一种现有方法，该方法旨在通过用户交互从单个透视图像估计相对深度。我们通过三种不同类型的演示来分析以交互方式为球形全景图提供此类深度信息的困难。然后，我们提出了一组基本工具来交互管理全景图的相对深度，以便以非常简单的方式获得构图。我们得出结论，通过扩展深度估计方法获得的相对深度足以通过一些基本的编辑工具合成新的真实感全景图。
