8.8 Outliers Correction
When the camera will be run in 3Donly mode, which is required for maximal frame rate,
then the following settings should be applied:
LineFinder_Mode = Mode_3Donly (category
LineFinder ), Peak0_3DY = 0 (category LineFinder / Peak0 / Peak0_3D ), Peak0_3DH = 1088
(category LineFinder / Peak0 / Peak0_3D, Width = 2048 (category ImageFormatControl ), Height =
4 (category ImageFormatControl )
If different exposure times will be used, calibrate the camera under the longest
exposure time.
2. Put the camera in free-running mode by setting the property
TriggerMode
to
Off
.
3. Start grabbing of the camera by clicking on the Play button.
4. Wait until the camera has achieved working temperature.
5. Close the lens of the camera or put a cap on the lens. The calibration requires an uniform
dark image. The black level offset should be set so that all pixels (except defect pixels)
have values above 0.
6. Set the visibility of the Device Control window of the PF_GEVPlayer to
Expert
.
7. Run the command ColCorrection_CalibrateBlack (category ColCorrection ) by clicking on
the corresponding button. The camera transmits a test image during calibration.
8. Run the command ColCorrection_Update by clicking on the corresponding button. Read the
ColCorrection_Busy value which should be 0 after the calibration has finished. Repeat this
step if its value is not 0. If the ColCorrection_Busy value doesn’t show 0 after various tries,
check if the camera receive triggers or set the TriggerMode of the camera to Off .
9. Check the values of the properties
ColCorrection_Overflow
and
ColCorrection_Underflow
. Both
should have the value 0 after calibration. If
ColCorrection_Overflow
is not 0, then decrease
BlackLevel (in category AnalogControl ) and re-run the procedure from step 6 on. If
ColCorrection_Underflow is not 0, then increase BlackLevel (in category AnalogControl ) and
re-run the procedure from step 6 on.
10. The Column FPN correction is now calibrated. The calibration values are stored in the
camera’s RAM and these values are lost when the camera power is turned off. To store the
calibration values to permanent memory see Section 8.7.3.
8.7.3 Storing the calibration in permanent memory
After running the calibration procedure (see Section 8.7.2) the calibration values are stored in
RAM. When the camera is turned off, their values are lost.
To prevent this, the calibration values must be stored in flash memory. This can be done by
clicking on the property
ColCorrection_SaveToFlash (in category Calibration ). Wait until the
command has been finished, i.e.the property ColCorrection_Busy (category Correction /
ColCorrection ) is 0. ColCorrection_Busy can be updated by clicking on the property
ColCorrection_Update (in category Calibration ).
Storing the calibration in permanent memory overwrites the factory calibration.
8.8 Outliers Correction
The Outliers Correction feature is explained in Section 5.7. This section shows its properties.
