Barrel Distortion
in [Matlab]
|
From: Aaron on 22 Mar 2010 15:34 I need to corret for barrel distortion in a number of images, all taken with the same camera at the same distance away from my target. Is a pin hole transform appropriate or will I need to create a polynomial transform? If I need to create a polynomial transfrom, are there any camera/lens calibration data sets availble?

There's some information (and perhaps source code available) here about barrel distortion correction: http://www.all-in-one.ee/~dersch/barrel/barrel.html http://www.all-in-one.ee/~dersch/ I also know of some papers which you can download here: http://sprg.massey.ac.nz/pdfs/2003_IVCNZ_408.pdf http://www.vassg.hu/pdf/vass_gg_2003_lo.pdf Another excellent tutorial (including some source code) can be found here: http://www.fho-emden.de/~hoffmann/bicubic03042002.pdf
