I do not believe that synchronization is possible.
See this thread.
I would like to know if it is possible to synchronize the live streaming from two ricoh theta Z1 in a linux distribution? Whether its possible to give an external trigger to initiate live streaming. Synchronization would become important for any stereo vision applications.
Thanking you in advance.
Usually, in multicamera systems, you can have an external physical device, sometimes the camera itself to send an external physical signal to initiate a capture. This would ensure that the capture occurs at the same time instant. Even if I use a USB API, I believe absolute synchronization can only be guaranteed from a real-time operating system but not with normal Ubuntu distribution. Such synchronized data is a necessity for multi-view applications like for finding correspondence to estimate d…
You will likely need to use three cameras, 2 that are not theta and a 3rd that is a theta.
For example on a Jetson Nano, get two cameras like this:

and then synchronize it like this:

Then, connect a RICOH THETA Z1 or V that is not in stereo for the 360 view and archival documentation.
There have been no success reports that I know of synchronizing two THETAs at the level needed for robotics vision research. There is no success synchronizing with an external clock. See the thread above.
The internal OS of the V is Android 7.
