math - correcting fisheye distortion programmatically
WebMar 19, 2010 · and the projection by common fisheye lens cameras (that is, distorted) is modeled by R_d = 2*f*sin (theta/2) You already know R_d and theta and if you knew the camera's focal length (represented by f) then correcting the image would amount to computing R_u in terms of R_d and theta. In other words, R_u = f*tan (2*asin (R_d/ (2*f))) WebApr 8, 2024 · Focal Length: A standard fisheye lens has a focal length of 8 mm to 10 mm, and a full-frame lens has a focal length of 15 mm to 16 mm. The Angle of View: The angle of view of a commonly used fisheye lens is 180° at its widest point. Image Distortion: The distortion of the image formed from the fisheye lens is called barrel distortion. WebMar 18, 2010 · The description you mention states that the projection by a pin-hole camera (one that does not introduce lens distortion) is modeled by.
