Fast 3D City Model Generation

Current Research
Fast, automated generation of photo realistic 3D models of city environments for the purpose of simulations and interactive walk-, drive-, or fly-thrus. This goal requires the combination of techniques from various research areas.
Airborne Modeling
Generation of 3D models of rooftops and terrain shape from airborne laser scans and photos.
- Processing airborne laser scans
- Reconstructing surface geometry
- Texture mapping
Ground-Based Modeling
Generation of 3D models of facades and street scenery as seen from street level.
It involves in particular:
- Ground-based data acquisition (challenge: huge amount of data)
- Position estimation using scan matching and Monte-Carlo Localization
- Automated segmentation, mesh generation, simplification and texturing
- Rendering (LOD & scene graph generation)
