Abstract:
Rendering images with lens distortion that matches real cameras
requires a camera model that allows calibration of relevant
parameters based on real imagery. This requirement is typically not fulfilled
for camera models used in the field of Computer Graphics.
In this paper, we present two approaches to integrate realistic lens distortions
effects into any graphics pipeline. Both approaches are based on the most widely
used camera model in Computer Vision, and thus can reproduce the behavior of
real calibrated cameras.
The advantages and drawbacks of the two approaches are compared, and both are
verified by recovering rendering parameters through a calibration performed on
rendered images.
