How do I connect multiple Orbbec cameras?

When I used OpenNI, I could connect several Orbbec Astra cameras (ex 3 camereas).

However, I want to connect multiple devices using the Astra API, but I do not know how.
If you know how, give me a hint.

Hi

I am deeply interested by your issue, if you have found a solution I would be pleased to hear about it.

Hi, anxio
Unfortunately, I gave up using the Astra API and used OpenNI instead.
So, functions such as registration, synchronization… ETC in API are implemented directly.
