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)))
