Student Research Assistant in 3D Semantic Building - Munich, Deutschland - Technische Universität München
Beschreibung
Creating detailed semantic 3D building models is a long- standing challenge in photogrammetry and computer vision. While methods
utilizing 2D building footprints and aerial imagery have enabled generating
models up to Level of Detail (LoD) 2, robust solutions achieving facade
- detailed semantic LoD3 models remain in infancy [1, 2].
Automated reconstruction of LoD3-specific facade elements is crucial for
or simulate floods. Our studies [1] suggest that mobile mapping data, par
- ticularly from units such as Google Street View, holds great potential for
semantic LoD3 facade modeling. However, utilizing such data requires ro
- bust automatic image projection, semantic segmentation, and reconstruction
algorithms.
Objectives In this project, you will be supervised by Olaf Wysocki and
work closely with Prof Biljecki's group of the National University of Singa
- pore. This position is for 8 hours/week, starting in April/May until the end
of the semester, September/October, with the possibility of extension; The
joint publication is foreseen
Your tasks will include:
- Acquiring automatically highquality streetlevel images from crowd
- Adapting existing image projection methods for the streetview image
- Testing and finetuning of the stateoftheart methods for facade se
- Analyzing the impact of image segmentation on 3D semantic recon
Requirements Sound programming skills in Python are required. Fa
- miliarity with libraries such as OpenCV, Open3D, and PyTorch is highly
advantageous. Understanding machine learning, computer vision, and pho
