 I understand that Dean Kaymen has now invented a super "sniffer" that can scout-out anyone within hearing distance that is remotely-involved with FIRST. - dhitchco [more] |

Re: Default Camera Calibration
Coarse adjustment of the zero position is mechanical. Power up the camera and center the servos (center = 128). Next remove the black philips screw holding the white encoder wheel to the servo. Reposition the axis and put the screw back. Repeat for the second axis. Note that you will probably have to loosen the screw connecting the pan linkage to the mount to remove the encoder wheel on the pan servo. Take your time and DO NOT bend anything.
Fine adjustment is in software. Kevin's code has a constant that represents the center position for each axis. It is set to 128 by default, Adjust that value after you do some shooting and determine to correct offset. Shoot from a good distance so you can do a fine adjustment. Good Luck, Keith Mentor-Team 1296 |
