Figure 5.21: Moving ROI principle
Laser Finder
The working principle of the laser finder is shown in Fig. 5.22. If the position of the laser line
suddenly jumps then the 3D-ROI might not contain the laser line anymore (image 1 in Fig.
5.22). If the laser finder is enabled (property Peak0_MovingROIEnLaserFinder=True) then one
image with a bigger ROI (laser finder window) is used to calculate the position of the next
3D-ROI. Note that some profiles might be lost during this process as it takes more time to read
out the laser finder window and therefore some triggers might be missed.
The criterion when the laser finder window should be used is based on the setting of the
property Peak0_MovingROIMinCol. If the number of columns with a detected peak falls below this
MAN052 12/2018 V3.2
Description
Enables moving ROI feature
Automatic recalibration of moving 3D ROI using a
bigger window
Force a repositioning of moving 3D ROI using a bigger
window
Vertical start position of the laser finder window and
minimal start position of a ROI in moving ROI mode
Height of the laser finder window. The ROI is only
moved inside the window specified by MovingROIRangeY
and MovingROIRangeH
Minimal percentage of columns (detected peaks)
required to calculate moving ROI
Minimal vertical distance of detected peak to upper
and lower boundary of 3D ROI. A violation sets the
corresponding bit in the status pixels.
Type of smoothing of peak positions used to
determine moving ROI window position. Available
values: None, MA8 and MA16
