8.2.5.2 Setting the DetectionThreshold parameter
Workflow step: Data collection
Prerequisites: Focus and exposure time have been adjusted for best image quality.
1. Turn the laser off.
2. Click Start to start the collection of 3D image data.
✓
Since the laser is turned off, only noise will be visible in the image.
3. Open the Parameter editor and select the Scan3dControl category.
4. Take a snapshot of the 3D image and adjust the DetectionThreshold parameter in
the following way:
°
If there is much noise in the image, increase the DetectionThreshold value.
°
If there is no noise in the image, decrease the DetectionThreshold value.
5. Repeat the previous step until DetectionThreshold has a low value without excessive
visible noise.
6. Turn the laser on.
8.2.5.3 Setting sensor region
Workflow step: Image
To adjust the height and position of the sensor region that is used to generate the 3D
image data (Region1, see "Extraction regions", page 25), follow the steps below.
NOTE
For best image quality, make sure that the whole width of the laser line is within the
region.
NOTE
The values of the Height and OffsetY parameters must be multiples of 4.
The value of the OffsetX parameter must be a multiple of 8.
The value of the Width parameter must be a multiple of 16.
1. In the Parameter editor, go to the ImageFormatControl category and set RegionSelector
to Region1.
2. Select the 3D extraction area check box in the upper right part of the GUI.
✓
A blue region corresponding to Region1 appears in the 2D image.
