Single Camera Calibration

Stanford University School of Engineering

Department of Mechanical Engineering

XX February 2000

Summary of one camera calibration

• Removal of spherical distortion (dewarp)
• Center pixel determination
• Thin lens model for underwater multi-lens system

  • Logistical

    • Platform construction
    • Gather data from cameras to test equations
  • Analysis

    • Focal point calculation (‘f’ and ‘h’)
    • Focal point calculation with spherical distortion removed?(will complete the pinhole approximation)

Center pixel determination
• CCDs aren’t mounted centered around the optic center (get real term here).
  • No real incentive for commercial manufacturers
  • Prof. Tomasi has seen some off by 10-15 pixels
