An Approach to Minimising Estimated Pincushion Camera Distortions
Abstract: Minimizing camera distortion has been a focus
of recent photorealism researches. Of the several types of camera distortions,
researchers concentrated on the radial distortion being the most severe part of
the total lens aberrations. Often, polynomial approximations by introducing
distortion-specific parameters into the camera model have been methods of
evaluating distortions. Of the two types of radial distortions, barrel, is the
most discussed probably because of its dominance in cheap wide-angle lenses. In
this paper, an approach to estimating and minimizing pincushion distortion by
using fundamental surface area properties of the distorted image is proposed.
This paper is significant as it reveals the importance of the topic and its
implications on the camera. Demonstrations using four camera lenses show the
robustness of this technique under different focal lengths conditions. The
reliability of the approach is justified by comparing the results with the
physical observations using (two tailed) t-test statistic.
