I have been using the barcode detection in a context when i want to detect barcode when they enter the view. It works just fine.
However, since – by default – pixy only sends you the signal that a given barcode has entered the view once, then i cannot detect when it leaves the view.
I need to creates a scenario when showing/hiding barcodes is a user interface. Therefore, I need to know for each frame, when a given code is there. I still want the filtering thing to happen.
barcode documentation suggests it’s possible to do so
Pixy2 can provide your program with all lines, intersections and barcodes that it detects
but does not clearly states how to configure it to do so (did not find a relevant parameters in any configuration tab).
How can I do that? (reminder: I would rather keep the filtering thing, or at least know from code if a given barcode is filtered or unfiltered (to reject false positives if any)
