Abstract
Systems and methods for obtaining mapping of Ultra Wide-Angle (UWA) lenses are disclosed. Captured image of a set of grid points on the inner surface of a precision made calibration dome is used as an input image. Image processing techniques are used to identify components of the image and compute the lens mapping. The lens mapping can be used to calibrate the lens against a standard or against other lenses. The mapping can further be used for perspective correction applications.
