We present an approach to generate a 3D model of a building including semantic annotations from image
series. In the recent years semantic based modeling, reconstruction of buildings and building recognition became
more and more important. Semantic building models have more information than just the geometry, thus
making them more suitable for recognition or simulation tasks. The time consuming generation of such models
and annotations makes an automatism desirable. Therefore, we present a semiautomatic approach towards
semantic model generation. This approach has been implemented as a plugin for the photostitching tool Hugin*.
Our approach reduces the interaction with the system to a minimum. The resulting model contains semantic,
geometric and appearance information and is represented in City Geography Markup Language (CityGML).
