Performance Tips
Your BOA Vision System is optimized for performance, but for very high-speed applications, it
may be necessary to minimize inspection overheads, to prevent “part skipping”. This can happen
if the inspection queue is full when a new part to inspect is detected. In most cases, this would not
be a problem given that the BOA Vision System can capture new images as it processes and ren-
ders a result on a previous image.
General guidelines for performance optimization
1. Fixture parts and orientation whenever possible.
2. Keep the Locator search pattern and movement area as small as possible. Remember to se-
lect a unique pattern in the image and position the rotation feature window diagonally away
from the primary feature and search window.
3. If the application permits, use the default accuracy parameters for a given tool.
4. Reduce the amount of information to be processed. Complex objects may require more
processing time.
5. Turn off history recording when your inspection criteria is well defined.
6. Turn off image data to the local display if it is not needed (Monitor panel, Display options).
In many applications it is a good idea to display failed images only.
7. If the internal timer setting, or the time between parts on the line, is less than the total inspec-
tion time, images may be dropped (resulting in missed inspections).
The Total Inspection Time is: Inspect Time; plus (approximately) 40 ms; plus client or network
overhead. The Inspect Time is displayed on the Monitor panel.
