Quick Calibration 

If during a measurement it is indicated that the system might be deca-

librated (e.g. if you slightly knocked against the cameras), you may 

perform a quick calibration.  
You reach the software dialog with

Quick Calibration

. 

During this process, the calibration object needs to be placed into 

three positions - in the center of the measuring volume, further away 

from the sensor and closer to the sensor. These three new images are 

combined with the original calibration and thus a new calibration is 

calculated for the following measurements.  
This method is fast and can easily be used during recording a mea-

suring project. 

 

However, the image characteristics of the cameras must not have 

changed! If, for example, you inserted new lenses, you need to per-

form a complete new calibration!  

 

The calibration cross must not have been taken apart during the last 

calibration and the quick calibration!
