Abstract
A system and method for correcting image distortion is provided. The system and method remaps pixel position of distorted images using a combination of radial distortion correction and tangential distortion correction lookup tables consuming less physical memory. The solution conserves both memory and memory access bandwidth. The radial distortion correction lookup table is formed by taking advantage of radial distortion being generally symmetric about a determined optical center of the camera lens. This symmetry allows for use of a quarter LUT for correction in all quadrants of a distorted image. In addition, tangential distortion can be corrected in a symmetric manner that saves memory space as well.
