B01 - Adaptive geometric-semantic multi-LOD road infrastructure construction model of the cyber-physical system (CPS) of the road

In TP B01, an adaptive geometric-semantic building model (GSM) with several abstraction levels is developed, which enables the spatial multi-scale representation of the real existing object and, thus, serves as a homogeneous spatial reference for all geometry-related tasks in the SFB/TRR 339. The automatic model derivation is based on the combination of computational geometry, knowledge-based approaches and machine learning methods. The GSM data can be used in different levels of detail (LOD) for simulations, visualizations and other purposes. For the description of the geometric-semantic reliability of the data, a novel combined quality measure is developed that allows for an uncertainty quantification for the required LOD.
