中文简介: | 三维内容是一种新颖的形式,用于导航,后期制作和电影摄影,建筑建模和城市规划等众多领域。这些领域得益于图像三维重建的巨大进步。这样的问题包括构建观察环境的几何模型。现有技术的方法可以在小规模上提供优异的结果,但是在本地并且不能在大规模重建过程中考虑,因为从多个视图中恢复对于重要数量的建筑物的图像的假设是相当不现实的。另一方面,在图形社区中已经进行了若干努力以用城市引擎创建内容。这些模型纯粹基于图形,并且给出一组规则(语法)以及架构(建筑物)字典可以产生虚拟城市。通过使用实际的城市模型以及建筑结构的知识,这样的引擎可以变得更加真实。开发基于图像的3D模型/规则/语法并将这些模型与实际观察结合起来是城市建模的最大挑战。从最小内容中解决大规模几何建模问题可以创造出新的世界表现手段以及新颖的市场和应用。在本次演讲中,我们将通过建筑语法提出一些关于大规模建模和重建的初步结果。 |
课程简介: | Three-dimensional content is a novel modality used in numerous domains like navigation, post production & cinematography, architectural modeling and urban planning. These domains have benefited from the enormous progress has been made on 3D reconstruction from images. Such a problem consists of building geometric models of the observed environment. State of the art methods can deliver excellent results in a small scale but suffer from being local and cannot be considered in a large scale reconstruction process since the assumption of recovering images from multiple views for an important number of buildings is rather unrealistic. On the other hand several efforts have been made in the graphics community towards content creation with city engines. Such models are purely graphics-based and given a set of rules (grammars) as well as dictionary of architectures (buildings) can produce virtual cities. Such engines could become far more realistic through the use of actual city models as well as knowledge of building architectures. Developing 3D models/rules/grammars that are image-based and coupling these models with actual observations is the greatest challenge of urban modeling. Solving the large-scale geometric modeling problem from minimal content could create novel means of world representation as well as novel markets and applications. In this talk, we will present some preliminary results on large scale modeling and reconstruction through architectural grammars. |
