Reduction of Image Size
5.3.1
Region of Interest (ROI) (2Donly mode)
This section describes the ROI features in the 2Donly mode where the camera behaves as a
standard area scan camera.
The maximal frame rate of the 2Donly mode is considerably lower than in the
3Donly mode.
Some applications do not need full image resolution. By reducing the image size to a certain
region of interest (ROI), the frame rate can be drastically increased. A region of interest can be
almost any rectangular window and is specified by its position within the full frame and its
width and height. Table 5.2 shows some numerical examples of how the frame rate can be
increased by reducing the ROI.
The ROI is determined by the following properties: OffsetX, Width, OffsetY, Height

5.3.2
Region of Interest (ROI) in 3D modes
The ROI definition in the 3Donly and 2D&3D modes is tailored to laser line detection.
The ROI is determined by the following properties: OffsetX, Width, Peak0_3DY and
Peak0_3DH. The minimal height of the laser triangulation region is 11.
There is a high speed mode that provides higher scanning speed at the cost of reduced data
accuracy.
The maximal frame rates for the MV1-D2048x1088-3D06 camera series are shown in Table 5.3.
"HS" refers to the HighSpeed mode (see also Section 5.2.13). The image (profile) width can be
set by the user.
Reducing the image width only increases the maximum frame rate if the interface data rate is
the limiting factor. This is the case when DataFormat3D = 3 or 4 and the height of the
triangulation region is 18 or less. See Table Table 5.4 for frame rates where DataFormat3D=3
resp. 4.
