Near this, equal changes in angle map to larger and larger changes in location on the image. This is what stretches the corners out in an ultra wide angle rectilinear lens. Another mapping function is image height = focal length * half angle of view ...

WebJan 8, 2013 · The function transforms an image to compensate radial and tangential lens distortion. The function is simply a combination of fisheye::initUndistortRectifyMap (with unity R ) and remap (with bilinear interpolation). See the former function for details of the transformation being performed. See below the results of undistortImage. WebNov 4, 2024 · The resulting image looks like a reflective surface of a sphere. This is a common type of fisheye lens. In comparison to the stereographic lens, this one does compress the margins. Below are some examples of this fisheye lens type: Canon EF f = 15 mm f/2.8 (1988) Minolta f = 16 mm f/2.8 (1971) Nikkor f = 10.5 mm f/2.8.

I haven't needed it, and I remember people who struggled with this stuff.
