Fisheye lens mapping function
http://www.e-perimetron.org/Vol_7_3/Boutoura_et_al.pdf WebGenerates a mapping that corrects image distortions caused by fisheye lenses. Given camera intrinsic and extrinsic parameters, and fisheye lens distortion model, generates a VPIWarpMap suitable to be used by Remap to undistort images captured by cameras equipped with fisheye lens. The mapping is defined by the following matrix equation:

WebFisheye Calibration Basics. Camera calibration is the process of computing the extrinsic and intrinsic parameters of a camera. Once you calibrate a camera, you can use the image information to recover 3-D information from 2-D images. You can also undistort images taken with a fisheye camera. The Computer Vision Toolbox™ contains calibration ... WebFisheye lenses can have many different mapping functions: Linear scaled (equidistant):, where is in radians. Practical for angle measurement e.g., star maps. PanoTools uses …
WebApr 23, 2024 · Tangent blows up near 90 degrees, so you cannot map a 180 degree field of view onto a plane. 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 ...
