Image-based 3D Reconstruction and Model Creation

In the past years, the interest and importance of image-based 3d reconstruction has increased significantly in the use of everyday applications. Especially the advancements of modern hardware and state-of-the-art algorithms, with respect to their performance, facilitate the use of real-time 3d information in numerous applications, such as (urban) navigation, scene interpretation, security surveillance, change detection and the operation of autonomous vehicles.

The Fraunhofer IOSB offers expertise, algorithms and solutions in a number of different research topics essential to image-based 3d reconstruction:

  • Simultaneous visual self-localisation and mapping (vSLAM), needed for the navigation in an known or unknown envorionment
  • Geographic localisation and registration, as well as calibration of a single camera or a camera network
  • Stereo vision based on a fixed stereo camera system
  • Scene reconstruction from a self-moving camera with Structure-from-Motion (SfM), as well as from a collection of unordered images with Multi-View Stereo (MVS)
  • Creation of digital ortho mosaics (DOMs) and digital elevation models (DEMs)
  • Visualisation of 3d data
  • Use and integration of commercial off the shelf (COTS) photogrammetry software and geoinformation systems (GIS)
