NOTE
Error message: "Too much contour points! Please reduce the number of contour points."
You may avoid this error with the following corrective actions:



(device dependant)
Activate the function "Use gamma correction" if you wish to emphasize contours in dark areas of the image.
This option may also be appropriate to reduce the effects of reflections when the image is acquired. This
makes the sensitivity of the acquisition non-linear, brightening darker areas of the image and diminishing the
contrast of brighter areas of the image.
NOTE
When using gamma correction, the "Reference surface" function can only be used to a
limited extent for individual feature checks (e.g. Brightness etc.)!
(device dependant)
This function enables a previously calibrated shading correction to be activated or the configuration page to
be opened.
The following value can be set via the process interface:
Entry value
Exposure time
Amplification
Edge sharpness
Trigger mode
Trigger delay
v2.11.0-B4
Adjust the application set-up:
-
For example, change the position of the object being examined so that
interfering structures that create unnecessary contour points are outside
of the image area
- Cover up the interfering structures.
Adjust the edge detection sensitivity.
Reduce the image noise using lower amplification and correspondingly longer
exposure or stronger illumination.
