How to acquire images from stereo cameras simultaneously?

As explained by JerryChang at this topic:

There’re two use-case:

  • [case 1] multiple sensors per multi sessions.

  • [case 2] multiple sensors per single session.

In our application, case 2 is used, just like syncSensor samples.

But instead of acquireFrame() sequentially in single thread, we call acquireFrame() in two threads separately.

Does this modification have any impact?

Thanks.
