Abstract: Systems and methods in accordance with various embodiments of the invention can generate term (or PolyMap) coefficients that properly calibrate any camera lens using information obtained from a calibration pattern (e.g., chessboard patterns). Term coefficients in accordance with several embodiments of the invention can be used to transform a warped image to a dewarped image by mapping image information from the warped image to the dewarped coordinates. Determining calibration coefficients in accordance with certain embodiments of the invention can include novel and inventive processes for capturing calibration images, processing the calibration images, and/or deriving inputs needed for proper calibration as described in this disclosure. Processes described in this description can provide for improvements in the field of image processing, especially in increasing the speed of dewarping processes and in the accurate capture of calibration pattern images.

Abstract: Systems and methods for correcting image distortion in accordance with embodiments of the invention are illustrated. One embodiment includes a method for correcting distorted images. The method includes steps for receiving a set of term coefficients associated with a lens that captured a set of one or more distorted images, and mapping each of the set of distorted images to a new target image based on the set of term coefficients.
