Algorithm for semi-automatic registration of 2D images on 3D scan images 

 

TECHNOLOGY

  • Algorithm to automatically register a scanned scene, represented by 3D Euclidean point coordinates, and two or more uncalibrated cameras
  • Images acquired from unregistered devices, even moving cameras
  • Establishes 2D-3D correspondences without triangulating image points

APPLICATIONS

  • Construction industry and civil engineering: 3D documentation of buildings, refineries...
  • Entertainment: 3D models for virtual reality
  • Cultural heritage: replaces casting and simplifies restoration
  • Forensic medecine: documentation of crime scenes
  • Medical imaging

ADVANTAGES

  • Global optimal solution (non-context specific)
  • Needs only rough knowledge of camera positions
  • Works with unscaled images
