2.
To change the exposure time, go to the
ImageSetup
view and adjust the
Exposure
parameter.
3.
Repeat steps 1-2 until the laser line is gray and the heightmap looks good.
4.
Adjust the
Gain
parameter if needed. A low gain value keeps the noise level down.
A high gain value increases the image brightness, but also increases the noise
level.
5.
Adjust the
LaserThreshold
parameter to determine which sensor intensity values to
include when locating laser peaks. A high threshold value gives less noise in the
heightmap, while a low threshold value makes it possible to detect weak laser
peaks.
6.
Select laser line acquisition criteria with the
PeakSelection
parameter:
°
Strongest
locates the point with the highest intensity in each column.
°
Top Most
and
Bottom Most
locate the highest or lowest point with an intensity
higher than the value set by the
LaserThreshold
parameter.
