8.2.5.1 Setting exposure time
Workflow step: Image
1. In the Parameter editor, set RegionSelector to Region0.
2. Look at the 2D image and the laser line and adjust the ExposureTime parameter
until the laser line is imaged as a narrow bright stripe and the background is not
visible, see the figure in the middle below.
Figure 34: Too short exposure time: Laser line hardly visible.
Figure 35: Normal exposure time: Laser line bright but not saturated. No background visi‐
ble.
Figure 36: Too long exposure time: Laser line wide and saturated. The background is visi‐
ble.
3. Set
RegionSelector to Region1.
4. Set the ExposureTime parameter to the same value as for Region0.
✓
This will give the 3D acquisition the same exposure time as the 2D image.
NOTE
If reflectance measurements are enabled, the exposure time can also be adjusted
using a reflectance image as reference. For details, see "Setting exposure time
using reflectance", page 59.
