Final   precision   is   0.** 

shows the calibration accuracy

.   

Memorize the measured value and close the 

calibration menu. 

Orientation 

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.
