Get accurate depth from two monocular cameras (working as stereo) by long distances ?
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
Youb will need a very large chessboard or you can use fixed point with gps coordinate(differential gps) or galileo with commercial service
You can try to adjust manualy orientation
Im more interesting in the approach for remote sensing using fixed point with gps coordinate. Any help where can find some more information how to implement it? What do you mean by try to adjust manually orientation?
You can read this (long base) http://www.ipb.uni-bonn.de/wp-content... or Stereographic methods for cloud base height determination using two sky imagers
i see this article use fish eye cameras. can be used with normal one? Is that need only stereo camera or also other sensor? I would like to use only stereo if possible and maximum stereo and laser range finder or stereo and but not LIDAR( laser scan)
also my camera has fixed focal length of 6mm.
