Description of the "Data Acquisition" View
Activates the "Set region of interest for histogram" mode. In this mode you may define a
rectangular range for each camera. Pixels which are inside the range will be used for
histogram analysis. In order to set a range, move the mouse pointer to the desired po-
sition, press the left mouse button and keep it pressed to draw out a range. This setting
has no influence on the computation of the measurement results.
Resets the region of interests respectively the region of interests for histogram. All pix-
els of the raw images will be used for computing the 3D point cloud respectively all pix-
els are used for histogram analysis.
Scales the displays so that the complete camera images will be shown.
Scales the displays to the original image size.
Note: The "Set region of interest" mode is only available when using a reflectCONTROL sensor.
Note: Changes of the region of interests and of the region of interests for histogram will be applied auto-
matically to the measurement view (see Chap. 4.2).
3 Raw images: The currently captured camera images are shown. The displays are updated con-
tinuously.
4 Histograms: The frequency distribution of the gray values from 0 to 255 in the region of interest
of the corresponding camera image is shown. The displays are updated continuously. Below,
the following information is shown:
- Underexposed pixels: The number of pixels whose gray value is smaller than three.
- Overexposed pixels: The number of pixels whose gray value is 255.
- Min. gray value: The minimum gray value of the corresponding raw image.
- Max. gray value: The maximum gray value of the corresponding raw image.
- Average gray value: The average gray value of the corresponding raw image.
Note: Use the Buttons
sponding display (raw image / histogram).
