Camera Calibration

NOTE: Clips can not be more than 10 seconds for HD video but clips from the other cameras can be longer. The only requirement is that the final avi must be less than 4 Gb (closer to 3 Gb, to be safe).

Image collection

MATLAB Camera Calibration Toolbox

HD camcorder

  • Run 1: Full-resolution frames (1080x1920), 53 images, large calibration pattern
    • Focal length (fc) = [ 1608.096495575887730 ; 1599.287922015898630 ] +/- [ 1.416325845823490 ; 1.327547699079502 ]
    • Principal point (cc) = [ 925.424428348655283 ; 586.161310112539127 ] +/- [ 2.437652429048954 ; 1.844740307952982 ]
    • Distortion coefficients (kc) = [ -0.036357504768588 ; 0.045264475073191 ; 0.006637738231113 ; -0.006035821879719 ; 0.0 ] +/- [ 0.004133200071201 ; 0.016990879400718 ; 0.000370417322208 ; 0.000486555757104 ; 0.000000000000000 ]
  • calib_data.mat: Calibration Data for HD Camera

Lipstick video camera

  • 600 line grayscale camera in shape of lipstick (well, just a cylinder really but "lipstick camera" sounds nicer than "cylinder camera")
  • Additional instruction for lipstick camera
    • To power lipstick camera:
    • To record video with camcorder:

Nikon camera

  • The still image (a.k.a. not camcorder/video) camera
