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 … Web26 de nov. de 2024 · off99555. 1. I saw that OpenCV's solvePnP () function assume that your camera parameters are from a pinhole model. But I calibrated my camera using cv.fisheye module, so I wanted to know how to use solvePnP with parameters obtained from that fisheye module.
