The algorithm is much more data lossless and accurate than such a classical approach like Brown-Conrady model. Image and Video Processing (eess.IV); Computer Vision and Pattern Recognition (cs.CV)
WebEach of the renders are done at 90 degree field of view and stitched together using the fish-eye projection mapping. This lens uses the equidistant mapping (also called tru-theta mapping). See Paul Bourke's page on Fisheye lens correction. In the following, all coordinates are normalized device coordinates in the image plane. WebA fisheye lens also called an “ultra-wide” or “super-wide” lens, is a type of wide-angle lens that captures an extremely wide photo, typically around 180°. The images they create are highly distorted, giving them a dynamic, abstract feel. Fisheye Lens History The fisheye lens has roots dating back to 1906. Inventor and physicist Robert W. […]
