Sensor regions
Data from the sensor is used as standard 2D image output and as input to the calcula‐
tion of the 3D data. The sensor region that is used when viewing the 2D intensity image
(
Region0
) and the sensor region used as input to the processing module (
Region1
) are
defined independently of each other.
The sensor region defines which area of the sensor to use. Using a smaller region on
the sensor enables measurements at a higher rate. The region is specified by the para‐
meters
OffsetX
,
OffsetY
,
Width
, and
Height
as shown in the figure below. The resulting
image generated by the device will have

pixels.
OffsetX
and
OffsetY
are
given with respect to the upper left corner of the image area. This corner has the coordi‐
nates (0,0) in the imager (x, y) coordinate system. All measures are given in pixels.
NOTE
In GenICam
TM
devices, such as Ranger3, imager coordinates are defined as (x,y). In
more general terms, image sensor coordinates are usually defined as (u,v),

Extraction regions
The extraction region (
Scan3dExtraction1
) uses input from a sensor region (
Region1
).
Together with a processing module, the extraction region defines the processing and
formatting conditions of the generated 3D linescan output data.
