Hello
I have two Cahmeleon3 mono cameras and made it work as stereo (as Master Slave) synchronized. I need to use them for long distances object detection and collision avoidance /obstacle detection. The range of the distances is up to 45m. I calibrate them and get intrinsic and extrinsic camera parameters as well. So as the camera focal length is fix by 6mm when apply the formula Distance = focal_length * baseline/disparity I will get big errors by long distances. So please can someone point out some method for long distance calibration or long distance remote sensing so can have accurate depth (within couple of cm error) estimation by long range distances thanks
