Fisheye images are attracting attention in computer vision such as autonomous vehicles and virtual reality because of the wide field of view (WFoV). However. fisheye images have geometric distortions caused by the refractive index of the lens. Conventional fisheye rectification methods require multiple images to calculate distortion coefficients and lens intrinsic parameters. https://www.diegojavierfares.com/save-now-Caire-SeQual-Eclipse-Battery-Cartridge-for-Eclipse-3-5-Concentrators-top-grab/
