matlab - How do I estimate the radial distortion parameters for a given image? -


i have found camera matrix image using dlt :

p =    3.8618e-03   7.1665e-04   1.9713e-03  -9.1510e-01   3.1222e-05   4.4639e-03  -7.6783e-04  -4.0317e-01  -5.9516e-07   1.1950e-06   1.7221e-06  -1.0115e-03

how proceed find radial distortion parameters.

tools: opencv/octave

the best thing calibrate camera. need take multiple images of planar calibration pattern, e. g. checkerboard.

if have computer vision system toolbox matlab, can use camera calibrator app.
