• PhD title: Geometric change detection in 3D models, model update and application to mixed reality experiences
  • Online access to the PhD thesis
• Thesis dates: 05/2020 – 09/2023
• Supervision: G. Moreau – J.-M. Normand – M. Krivokuća
• Context/Funding: CIFRE Interdigital
• General Goal:
  • To obtain fast and accurate updates of 3D scenes by considering limitations and purposes of mixed reality devices
• Scientific challenges:
  • To propose an exhaustive and maintainable scene model with regards to the need of the mixed reality experience
  • To develop a process to compare an outdated model with current data from the real scene and detect meaningful changes, to modify the model and preserve its accuracy
• Keywords: Mixed Reality, Change detection, Semantic analysis
• Contribution:
  • Projection-based photo-geometric scene change detection method using heterogeneous data to represent the scene’s states (images and mesh)
• Perspective:
  • Semantic scene analysis and representation using graphs
