实时重建物理世界一直是计算机图形学和三维视觉领域的一大挑战。在本文中,我们介绍了一种交互式管道,以在两个细节层次上重建镜像世界。在给定一对纬度和经度坐标的情况下,我们的管道流传输并缓存深度地图、街景全景图以及从Google Maps和OpenStreetMap API构建多边形。对于特写视图,在细节级别上,我们使用相邻的本地街道视图和深度贴图来渲染纹理网格。当从远处观察时,我们将投影贴图应用于从建筑多边形挤出的3D几何图形,以获得粗略的细节级别。与隐形传态不同,我们的系统允许用户在街道水平上虚拟地漫游镜像世界。我们通过将我们的方法整合到混合现实社交平台Geollery中来展示我们的方法的应用,并在包括手机、工作站和头盔显示器在内的各种平台上验证我们的实时策略。
Reconstruction of the physical world in real time has been a grand challenge in computer graphics and 3D vision. In this paper, we introduce an interactive pipeline to reconstruct a mirrored world at two levels of detail. Given a pair of latitude and longitude coordinates, our pipeline streams and caches depth maps, street view panoramas, and building polygons from Google Maps and OpenStreetMap APIs. At a fine level of detail for close-up views, we render textured meshes using adjacent local street views and depth maps. When viewed from afar, we apply projection mappings to 3D geometries extruded from building polygons for a coarse level of detail. In contrast to teleportation, our system allows users to virtually walk through the mirrored world at the street level. We present an application of our approach by incorporating it into a mixed-reality social platform, Geollery, and validate our real-time strategies on various platforms including mobile phones, workstations, and head-mounted displays.
