Fisheye lens mapping function
WebSep 28, 2024 · A fisheye lens is an ultra-wide-angle lens that produces a strong visual distortion intended to create a wide panoramic or hemispherical image. These lenses … 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.

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.
