Final precision is 0.**
shows the calibration accuracy. Memorize the measured
value and close the calibration menu.
Short Calibration function (orientation)
is used to test the accuracy of calibration.
This is a simplified version of full calibration, the calculation occurs after the one
capture of calibration plate in the initial position (at the working distance from the
scanner). Orientation is also used to configure to the scan area № 1.
After performing the
Full calibration
before the scan, perform
Orientation
. Measured
value of
Final precision
must be less than 0.1 pix
. If the value has proved to be greater,
perform calibration again, taking care of warm-up of the cameras, the position of
calibration plate and the size of the plate specified in the program.
Example 1
: A complete calibration result was
final precision 0.095 pix
,
after
Orienting - 0.076 pix
. Scanner calibration
has been performed
.
Example 2
: A complete calibration result was
final precision 0.124 pix
,
after
Orienting - 0.11 pix
. Scanner calibration
has not been performed
, it is necessary to
calibrate again.
To calibrate for the scanning zone №1, first you must perform calibration for
scanning zone №2. Than you need to close ScanCenter, move cameras to positions for
scanning zone №1 (to do this you will have to temporarily disconnect USB cables) and
again launch ScanCenter.
Letting cameras to warm up, install calibration plate on the distance 65 - 70 cm
from the scanner and perform
Orientation
. Turn on Stripes and Lines and check the
projector focus.
