An apparatus comprising an interface and a processor. The interface may be configured to receive pixel data corresponding to a wide angle field of view from a lens. The processor may be configured to receive a distortion specification corresponding the lens, generate pixel data arranged as a single calibration image in response to the wide angle field of view of the lens, perform calibration operations in response to the distortion specification and the single calibration image, and determine a distortion curve configured to correct a distortion of the lens in response to the calibration operations. A calibration scene may be captured in the single calibration image. The calibration scene may comprise three planes with a dot pattern. The calibration operations may comprise calculating an optical center of the lens and calculating the distortion curve in response to the dot pattern.
