DEVICE AND METHOD FOR CORRECTING LENS DISTORTION

摘要

According to an embodiment of the present invention, a lens distortion correction device includes: a distortion function definition unit which uses a field of view (FOV) model to define a distortion function; an inverse function derivation unit which derives the inverse function of the FOV model from the distortion function; and an image distortion correction unit which uses the inverse function of the FOV model to correct the distortion of the image recorded through a spherical fisheye lens.
