5.3. General considerations
A correct configuration based on the acquisition of a good-quality reference image is necessary to
ensure accurate inspection.
The term inspection means the set of operations the sensor performs to check the features of an
object for compliance with certain specifications.
Each individual object is compared to the reference image to determine whether it meets the
specified requirements.
For this reason, the reference image must have neat contours and clearly visible features.
Here are a few tips to facilitate correct configuration:
• Decide exactly which feature of the product must be monitored
• Make sure that the lighting is correct and, above all, as consistent as possible: correct image
acquisition is achieved by minimising the influence of the environmental light in the area being
monitored (
)
• Make sure there is good contrast between the object being monitored and the background
• Carefully choose the tools (or "controls") to be used for the elaboration in order to achieve the
best results as quickly and easily as possible
• Carefully adjust the control parameters
• It may be useful to perform preliminary tests to detect which cases are the most difficult to
define and adjust the tolerances accordingly
• Compare the results to detect any inconsistent results
5.4. Step 1 - Configuration of the camera settings and choice of the inspection tool
When the VSC configurator is powered up, the welcome screen will be displayed on the monitor.
After a few seconds from start-up, the system will automatically move into Monitor Mode and display
the focus range of the vision sensor, with the current inspection in the region of interest (ROI).
