number (as a percentage) then the laser finder window will be used. E.g. if
Peak0_MovingROIMinCol is set to 50 and the width of the ROI is set to 2048, then a laser finder
window is used when less than 1024 columns (50 % of 2048) carry a valid laser detection (peak
coordinate bigger than 0).
Note that in 2D&3DMode only the lower part of the laser finder window (up to the height of
the 3D-ROI) is sent to the camera output as the dimension of the output window must remain
constant.
The horizontal position (X and W) of the 3D-ROI and the laser finder window
is the same and is set by the properties
OffsetX and Width . These values are not
altered by the moving ROI feature.
If the laser finder is disabled and the number of columns with a detected laser
line is less than the value of
Peak0_MovingROIMinCol
then the position of the 3D-
ROI is not modified.

Moving ROI and status information
Some values specific to the moving ROI feature are available in the status information fields
(see Section 5.10.2). Specially the moving ROI status can be useful to monitor.
Moving ROI smoothing
The moving ROI feature uses the minimal and maximal laser line coordinate to calculate the
position of the 3D-ROI. If there are outlier pixels, e.g. due to reflections then the calculation
can produce a window position that is not optimal. In this case it might be better to smooth
the laser coordinate prior to the position calculation. The property
Peak0_MovingROISmoothing
sets the smoothing level:
None No smoothing is applied
MA8 A moving average of 8 pixels is used for smoothing
MA16
A moving average of 16 pixels is used for smoothing which results in the highest
amount of smoothing
