中文摘要: 基于过程的建模技术是当前城市建模研究的新途径之一,但是建筑语义规则大多由人工创建或由单幅图像交互生成,建筑组件简单,建模效果逼真度较差。因此,本项目将研究基于多尺度照片集的城市过程建模技术,利用照片集多尺度、多视点、多光照的特点,研究建筑规则自动生成,建筑组件逼真建模,结合GIS和卫星图像数据的城市道路及场景建模等理论、方法和关键技术,主要包括:建筑语义规则的表示方法,基于数据驱动的建筑语义规则生成方法;研究基于多尺度室外场景图像重构建筑组件几何和反射属性的建模方法;研究基于GIS数据和卫星图像的城市场景快速构建方法。研究成果在"智慧城市"构建、文化遗产数字化,数字娱乐与游戏等领域具有重要应用价值。

英文摘要: Procedure-based modeling is one of the new ways for urban modeling. But, the architecture semantic rules are mostly created manually or generated interactively from single view image, architecture components are simple, and the fidelity of the modeling results is bad. So, this project will study procedure-based urban modeling based on multi-scale photo gallery. Take advantage of multi-scale, multi-view and multi-lighting of the photo gallery, we will explore the theories, methods and key technologies of building architecture semantic rules automatically, modeling architecture components realistically, and modeling urban road based on GIS data and satellite images, which mainly include study the representation and data-driven generation method of architecture semantic rules; the modeling method of architecture components geometry and reflectance based on multi-scale and outdoor photo gallery; the fast urban construction method based on GIS data and satellite images. The research results will play an important application value in the domain of "smart city" construction, cultural heritage digitization, digital entertainment and game.
