have a video level no less than 70% that of the brightest target). If the
brightness is less uniform than this, it will be necessary to adjust the ‘aiming’
of the illuminating LEDs.
Check that most of the targets that can be seen in the image are being
recognised by the system and are annotated with their barcode numbers.
If any target barcode values are
missing (or are replaced with a x or +
symbol), and there is no obvious
reason such as the target being
partially
obscured or damaged,
suspect that the focus is not correctly
set for the studio height. If it is
necessary to change the focus, even
slightly, it is essential that the
free-d™
camera be re-calibrated afterwards.
To maximise the depth-of-field, ensure that the exposure-time control (S102)
is set to position ‘D’; this is the position where the LED array appears to be
brightest.
If high-speed camera movements are anticipated, it may be desirable to
reduce the exposure time. See appendix E.
