Multiple similar object targets in one DB

March 20, 2019 - 6:22am #1

Good day! In our poject we use multiple object targets, scanned from globes. The differences between them are text labels, printed on various languages. Now we have only 2 languages and project works fine. But would there be any probjems with many similar object targets in one DB?

We dont really care if it would track incorrect globe from base, since all content is tied to app choosen language, we afraid of the situations, where no marker would be active because of conflict. So should we split our app for different languages or it is acceptable to have multiple similar targets in one base? Thanks.

Hello @Rivo,

Agree with @dpizzle here in that it would have to be tested. We normally caution against using text in Image Targets as the differentiating feataure due to text's propensity to create repetitive patterns.

Unfortuantly, I don't think there's anyway to know without testing it.  I think it depends how many feature points the text labels create vs the other features of the globe.  If they are minimal then it might work, but again, no way of knowing without testing first.
