| 中文简介: |  真实感地图是用于大型室内环境（例如博物馆和企业）的有用的导航指南。然而，从空中的观点来看，不可能获取覆盖大的室内环境的照片。本文提出了一种3D重建和可视化系统，该系统可以自动生成干净且规则化的纹理映射3D模型，以用于大型室内场景，包括地面照片和3D激光点。关键组件是一种称为逆CSG的新算法，用于重建由体积图元组成的构造实体几何（CSG）表示形式中的场景，该算法施加了强大的正则化约束来利用结构规则性。我们还提出了几种调整3D模型的技术，使其适合从空中视点渲染3D地图。可视化系统使用户能够从鸟瞰图轻松浏览大规模的室内环境，定位特定的房间内部，飞到感兴趣的地方，查看身临其境的地面全景视图并再次进行缩放，所有这些都具有无缝的3D过渡效果。我们在各种博物馆中展示了我们的系统，包括纽约市的大都会艺术博物馆，这是世界上最大的美术馆之一。 |
| 课程简介: | Photorealistic maps are a useful navigational guide for large indoor environments, such as museums and businesses. However, it is impossible to acquire photographs covering a large indoor environment from aerial viewpoints. This paper presents a 3D reconstruction and visualization system to automatically produce clean and well-regularized texture-mapped 3D models for large indoor scenes, from ground-level photographs and 3D laser points. The key component is a new algorithm called Inverse CSG for reconstructing a scene in a Constructive Solid Geometry (CSG) representation consisting of volumetric primitives, which imposes powerful regularization constraints to exploit structural regularities. We also propose several techniques to adjust the 3D model to make it suitable for rendering the 3D maps from aerial viewpoints. The visualization system enables users to easily browse a large scale indoor environment from a bird's -eye view, locate specific room interiors, fly into a place of interest, view immersive ground-level panorama views, and zoom out again, all with seamless 3D transitions. We demonstrate our system on various museums, including the Metropolitan Museum of Art in New York City - one of the largest art galleries in the world. |
