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.
