I need a camera matrix (fx, fy, cx, cy) for calling cv::projectPoints. My camera cannot be calibrated, but I got the parameters of the camera:
focal distance: 1.8
focal length: 4.8
aperture: 4.0
sensor width: 5.63
sensor height: 5.63
horizontal resolution: 1024
vertical resolution: 1024
How can I calculate the camera matrix for my camera?
