Appendix 1: Camera flow including barcode processing
This appendix contains the workflow of the camera process, including the box barcode processing flow.
Product match
The correct products should be detected if the
product is matched with the correct camera job.
First the product (pattern) is found. Secondly a
check is done on the amount of products found
to make sure it was indeed a correct product
(self check) by default the camera job is set to
detect 50% of a full box (full box defined per job)
with dummies subtracted from this total.
