[2010.10295] Fisheye lens distortion correction
A fisheye lens is an ultra wide-angle lens that produces strong visual distortion intended to create a wide panoramic or hemispherical image. Fisheye lenses achieve extremely wide angles of view, well beyond any rectilinear lens. Instead of producing images with straight lines of perspective (rectilinear images), … See more Panoramas with fisheye distortion predate photography and the fisheye lens. In 1779, Horace Bénédict de Saussure published his downward-facing fisheye view of the Alps: "All the objects are drawn in perspective from … See more For a comprehensive list of all current and all past fisheye lenses, see External Links below. Noteworthy fisheye … See more • Many planetariums now use fisheye projection lenses to project the night sky or other digital content onto the interior of a dome. See more Unlike rectilinear lenses, fisheye lenses are not fully characterised by focal length and aperture alone. Angle of view, image diameter, projection type, and sensor coverage all vary independently of these. Image diameter and coverage In a circular fisheye … See more • An image of the Louvre museum entry taken with the 7.5 mm f/5.6 circular fisheye Nikkor lens • Fisheye used to capture entire Wells … See more • Fisheye projection theory • List of all Current and all Affordable Photography Fisheye Lenses • The New Fish List, Luca Vascon, 2024 See more WebJan 28, 2024 · fisheye lenses usually require a mapping to cylindrical or equirectangular (!= rectilinear) projection. anything based on mapping to flat planes must fail. last I checked, OpenCV has some code for calibrating "super-fisheye" (>180 degree) lenses (weird definition but ok). I haven't needed it, and I remember people who struggled with this stuff. WebThe fisheye projection here is assumed to perfect, that is, a linear relationship between radiu from the center and field angle. For compositing not that not all physical fisheye lenses are linear, although it is straightforward to convert non-linear fisheyes into linear ones, and visa-versa, see: Fisheye lens correction. cannot install to same path
