本文描述了一个混合现实（MR）应用程序，该应用程序将历史遗址的丢失建筑叠加到使用球形航空图像虚拟的真实场景上。拟议的应用程序设置在日本的联合国教科文组织世界遗产地，并基于一个新颖的框架，支持将虚拟物体叠加到虚拟真实场景上。提出的框架利用基于图像的呈现（IBR），使用户能够在使用预捕获的图像构建的真实世界虚拟化中自由地改变他们的视点。该框架将虚拟对象的离线渲染与IBR相结合，在不增加在线处理的计算成本的情况下，充分利用了离线渲染的高质量；也就是说，它只需要在线轻量级IBR的成本，它通过结构化视点的预生成（例如，在网格点）来简化。
This article describes a Mixed-Reality (MR) application that superimposes lost buildings of a historical site onto real scenes virtualized using spherical aerial images. The proposed application is set at a UNESCO World Heritage site in Japan, and is based on a novel framework that supports the photorealistic superimposition of virtual objects onto virtualized real scenes. The proposed framework utilizes Image-Based Rendering (IBR), which enables users to freely change their viewpoint in a real-world virtualization constructed using precaptured images. This framework combines the offline rendering of virtual objects and IBR to take advantage of the higher quality of offline rendering without the additional computational cost of online processing; that is, it incurs only the cost of online lightweight IBR, which is simplified through the pregeneration of structured viewpoints (e.g., at grid points).
