Enrichment and multi-purpose visualization of building models with emphasis on thermal infrared data

该方案解决了丰富、更新和可视化3D建筑模型方面的问题。通过数据匹配，将地籍信息与单个建筑物的三维几何形状相结合；通过图像分析，结合三维建筑模型的上下文信息，从热红外数据中提取和解释不可见特征；利用不可见特征信息更新和丰富三维建筑模型。4)可视化描述更新和丰富的三维建筑模型的各种表面元素的语义属性，重点是随时间变化的热信息。所涉及的任务将由制图系和摄影测量与遥感系共同完成。来自选定的测试城区的数据源包括：1)单个建筑物的多面体描述，2)嵌入在城市规划、地籍地图和房地产数据库中的许多建筑物属性，3)热红外图像（…）。

The proposal addresses for the aspects of enrichment, updating and visualiziations of 3D building models. It serves four principal goals 1) to integrate the cadastral information with the 3D geometries of individual buildings by means of data matching, 2) to extract and interpret non-visible features from thermal infrared data based on image analysis coupled with context information from 3D building models, 3) to update as well as enrich the 3D building models with the information derived from non-visible features, and 4) to visualize semantic attributes describing various surface elements of updated and enriched 3D building models with emphasis on time-dependent thermal information. The involved tasks will be jointly accomplished by the Department of Cartography and the Department of Photogrammetry and Remote Sensing. The data sources from a selected test urban area include: 1) polyhedral descriptions of individual buildings, 2) a number of bulding attributes embedded in city plans, cadastral maps and real estate databases, 3) thermal infrared images (...).
