3D extraction processing module
In Linescan 3D mode, the Height and Width parameters of the region Scan3dExtraction1
define the dimensions of the 3D extraction output frame. Typically, the Width parameter
of an extraction region is locked to the same value as the Width of the source region on
the sensor.
To get a 3D image, several 2D images are required. Each 2D image corresponds
to one profile, see "Measuring with a 3D camera", page 13. The 2D sensor images
are transformed into lines in the 3D extraction output frame. Each line in the frame
corresponds to one 2D image. This means that the Height value of the frame tells how
many 2D images that are used to generate the resulting 3D image. The 3D image has
Width times Height pixels.
The RangeAxis parameter defines how the lines in the 3D extraction output frame are
visualized. The parameter is set to Reversed by default, which means that high values in
the range data correspond to low values on the imager Y axis. If the parameter is set
to Standard, high range values correspond to high values on the imager Y axis and the
visualized 3D object appears upside down. See figure 16 and figure 17 for examples.

8.4.3 Device scan type
The camera can be configured to output either the raw data from the image sensor or
the 3D profile data. In the user interface, you select Image to see the raw sensor data as
a 2D image or Data collection to get the 3D profile data, see "Workflow steps", page 52.
The camera uses the parameter DeviceScanType to control if 2D images or 3D profiles
are acquired. This parameter is set when you select Image or Data collection. Setting
the DeviceScanType automatically sets the relevant features for the correct mode, as
described below.
Image
DeviceScanType is set to Areascan.
The following settings are done automatically:
RegionMode[Region0] = On
RegionMode[Region1] = Off
RegionMode[Scan3dExtraction] = Off
