Due to the climate problem, one of the primary objectives of the German government is to optimize
the energy and transport sectors. The coupling of the two sectors can offer synergies, which can
compensate for the disadvantages of individual solutions (grid stability, costs, etc.). One current topic, for example, is
e-mobility charging infrastructure that is powered by locally generated solar energy.
. Semantic 3D city models based on the open source standard CityGML represent the
geometry, the external appearance as well as thematic and topological aspects of cities and
landscapes in a structured data model. Today, CityGML city models are available throughout Germany.
and are an ideal basis for a multitude of analysis methods, such as e.g.
for the large-scale simulation of solar irradiation. An existing problem here is that for the
relevant details for the analysis, e.g. roof structures, are not yet included in the models. Here, existing
existing AI methods that are able to recognize roof structures in aerial images.
The goal of this master thesis is to combine an existing simulation tool for solar irradiance with
with an existing AI method for the detection of roof structures to enable optimizations for both
for both approaches. In the course of the work, it will be investigated and quantitatively evaluated
which added value the linkage brings for both methods.
The exact geometry representation of the city model will be used to optimize the learning process of the AI.
learning process of the AI by pre-segmenting roof areas. Subsequently, the roof structures recognized by the
the 3D city model to improve the accuracy of the solar potential analysis.
solar potential analysis. The entire analysis workflow is to be encapsulated in Docker containers and
and be implemented in a modern cloud environment.
