Thanks for clearing that up. I also did a few tests of my own just to fully understand what was going on and how Vuforia detects duplicates. My tests are as follows:
Test 1: Uploaded two targets that use the same image and both were initially set to INACTIVE; duplicate check failed to report duplicates.
Test 2: Uploaded two targets that use the same image and both were initially set to ACTIVE; duplicate check worked for both targets i.e. each target reported the other as a duplicate.
Test 3: Uploaded one INACTIVE target while another ACTIVE target with the same image already existed in the system; duplicate check worked for the newly uploaded INACTIVE target.
Test 4: Uploaded one ACTIVE target while another INACTIVE target with the same image already existed in the system; duplicate check failed for the newly uploaded ACTIVE target.
Based on what you said in the previous post, I understand that you can perform a duplicate check on INACTIVE targets, but, in my opinion, what the documentation fails to explain (and what I now understand through the tests I did) is that the duplicates check API call will only look for duplicates among the ACTIVE triggers and will ignore any duplicates targets that are INACTIVE. In other words, if a target is INACTIVE, it will never be considered as a duplicate for another target. I think that is where the documentation is vague and confusing.
Can you please confirm that I now have the correct understanding of the duplicates check API call and that this is in fact how it works?
Lastly, can you also let me know how Vuforia decides which target to pick when a user scans an image that has duplicate targets. Does it choose one of the duplicate targets at random or in the order as returned by the underlying database that stores these targets, does it return the very first duplicate target that was uploaded into the system or perhaps the latest uploaded target? Any insight into this would be extremely helpful.
Once again, thank you for your time, effort and patience in helping me understand the Vuforia system.
