1. A method for correcting distorted images, the method comprising:
generating a set of term coefficients associated with a lens that captured a set of one or more distorted images by:
generating a set of coordinate maps;
fitting a set of mapping functions to mapping slices of the coordinate maps;
fitting a set of mapping coefficient curves to coefficients of the set of mapping functions; and
determining the set of term coefficients based on coefficients of the set of mapping coefficient curves;
receiving the set of term coefficients associated with the 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.
