Author:De Villiers, J; Wilson, F; Nicolls, FDate:Nov 2011A variety of lens distortion modelling techniques exist. Since they make use of different calibration metrics it is difficult to select one over the others. This work aims to compare lens distortion modelling techniques and calibration patterns ...Read more
Author:De Villiers, JP; Cronje, J; Nicolls, FCDate:Apr 2011Inverse lens distortion modelling allows one to find the pixel in a distorted image which corresponds to a known point in object space, such as may be produced by a RADAR. This paper extends recent work using neural networks as a compromise ...Read more
Author:De Villiers, Johan P; Leuschner, FW; Geldenhuys, RDate:18 Jan 2010Most current lens distortion models use only a few terms of Brown's model, which assumes that the radial distortion is dependant only on the distance from the distortion centre, and an additive tangential distortion can be used to correct ...Read more
