Zusammenfassung:An example apparatus enabling a dual fisheye model and calibration is described. The apparatus includes at least one memory; and at least one processor to execute instructions to: generate a first set of coefficients for an inverse distortion polynomial, the inverse distortion polynomial indicative of radial distortion of an image captured by a camera; generate a second set of coefficients for an alternative distortion polynomial, the alternative distortion polynomial to enable identification of a first point in the image corresponding to a second point in a three-dimensional space represented by the image; and determine a location of the camera within the three-dimensional space based on at least one of the inverse distortion polynomial or the alternative distortion polynomial.
