it is widely discussed in this forum, how to sync multiple cameras (e.g. best done via hardware trigger). Now I'd like to know how to actually determine the time delay between two image streams and the overall offset between a real event, and the moment when the captured frame is available in the PCs buffer.
So I have a picture P which captured an event at time T, so the captured image will be available at P(T+dT). How to determine dT?
I have two cameras capturing picture P1 and P2. But due to two unsynchronized shutter, P_1 will be captured at T_1 and P_2 will be captured at T_2. How to determine dt=T2-T1?
PS.: I really don't want to synchronize the cameras, just determining these delays. I searched intuitivley for publications on multi camera/Kinect tracking or Event Related Synchronisation but weren't lucky at all. Does someone has some suggestions?
