5.2.14 Moving ROI
Overview
The Moving ROI feature automatically centers the ROI vertically based on the detected 3D
coordinates.This allows to set a smaller region of interest (ROI) and therefore achieve a bigger
frame rate.
The Moving ROI feature is specially suitable for scanning of flat surfaces.
The Moving ROI feature is available in 2D&3D mode and in 3DOnly mode.
The Moving ROI is not available in High Speed mode.
Property Description
Peak0_EnMovingROI Enables moving ROI feature
Peak0_MovingROIEnLaserFinder Automatic recalibration of moving 3D ROI using a
bigger window
Peak0_MovingROIForceLaserFinder Force a repositioning of moving 3D ROI using a bigger
window
Peak0_MovingROIRangeY Vertical start position of the laser finder window and
minimal start position of a ROI in moving ROI mode
Peak0_MovingROIRangeH Height of the laser finder window. The ROI is only
moved inside the window specified by
MovingROIRangeY
and
MovingROIRangeH
Peak0_MovingROIMinCol Minimal percentage of columns (detected peaks)
required to calculate moving ROI
Peak0_MovingROIMinDistance Minimal vertical distance of detected peak to upper
and lower boundary of 3D ROI. A violation sets the
corresponding bit in the status pixels.
Peak0_MovingROISmoothing Type of smoothing of peak positions used to
determine moving ROI window position. Available
values: None, MA8 and MA16

Mode of operation
The mode of operation of the moving ROI featue is shown in Fig. 5.17. The vertical start
position of the 3D-ROI is automatically adjusted so that the detected laser line lies in the center
of the ROI.
The height of the 3D-ROI (property Peak0_3DH ) must be big enough to contain the laser line.
The 3D ROI height must have enough margin to contain the movement of the laser line from
one profile to the next profile.
