Opencv fisheye to pinhole
Web20 de fev. de 2024 · I have a stereo camera setup which has one pinhole camera and one fisheye camera. The pinhole camera has 40 degrees FoV. The fisheye camera has 120 degrees FoV. In the end, I want to get a depth map from this camera setup. However, I got a bad rectification result before I implemented stereo matching. I use python OpenCV to … WebThe image of the point P is p whereas it would be p0 by a pinhole camera. Perhaps the most common model is the equidistance projection. The behavior of the different projec-tions is illustrated in Fig. 1(a) and the difference between a pinhole camera and a sh-e ye camera is shown in Fig. 1(b). The real lenses do not, how-ever, exactly follow ...
