当前的 3D 城市模型已适用于全球许多城市。然而，历史名城模型的制作仍处于起步阶段。本文提出了一种结合不同数据源的程序，以使用自由汉萨城市汉堡为例，得出不同时期的单独 3D 城市模型。 1644 年的城市木制模型和 1859 年的官方地图被用作生成 4D 城市模型的基础。通过条纹投影系统扫描物理模型 (~1:1000) 进行 3D 建模，同时将地图中的数字化数据与来自不同数据源的高度信息相结合。这两个地理参考 3D 城市模型用于通过城市的不同历史鸟瞰图（等距视图）推导出更多纪元（1200 年、1400 年、1589 年和 1700 年）。为了实现 4D 城市模型的交互式导航和可视化，我们使用 Google 地球应用程序编程接口开发了一个程序。
Current 3D city models are already available for many cities world-wide. However, the production of historical city models is still in its infancy. In this paper a procedure is presented that combines different data sources in order to derive individual 3D city models of different time periods using the example of the Free and Hanseatic City of Hamburg. A wooden model of the city from the year 1644 and an official map from 1859 have been used as a basis for the generation of the 4D city model. The physical model (~1:1000) was scanned by a fringe projection system for 3D modelling, while the digitized data from the map were combined with height information from different data sources. These two geo-referenced 3D city models were used to derive further epochs (1200, 1400, 1589 and 1700) using different historical bird’s-eye views (isometric views) of the city. For interactive navigation and visualization of the 4D city model a program was developed using the Google Earth Application Programming Interface.
