Revision as of 09:40, 6 December 2012

This page shall help to define a calibration procedure. Please add your knowledge.

Things to calibrate

  • nonlinear effects for both cameras:
    • radial distortion On Wikipedia
    • tangential distortion (sensor chip not parallel)
    • rotational errors (sensor rotated on image plane)
  • Intrinsics matrix for both: Video camera & Depth Camera
  • Extrinsics matrix for both: Video camera & Depth Camera
  • Registration of both cameras (Registration as meant in This Article, please add a nicer description, if you know one)
    • Rotational tolerances
    • ?

Questions to answer

  • Which parameters change much between different devices?
  • Which change minor (and can possibly be set constant)?
  • Are routines to calculate parameters needed, or could a seperate application be used (based on OpenCV, for example)
