Vicon system and Intel depth cameras compatability.
I am planning to use two D435i cameras. According to the documentation, the D435i supports external triggering using an external signal generator. I intend to use the Vicon System's Lockbox as this signal generator, which provides TTL pulses, to trigger the Intel depth cameras at my convenience. My goal is to synchronize both systems.
I need some insights on this topic.

Hi Harshith Ylbf52 Yes, you can use an external signal generator (an oscilloscope, for example) to produce a trigger signal. It is difficult to implement though, as the frequency of the generated pulse has to be matched very closely with the 'actual' FPS speed of the camera (such as '30.015'). More information about this can be found in the External Trigger section of Intel's hardware sync guide.

It is easier to implement an externally generated trigger using genlock hardware sync. This feature is no longer officially supported by Intel but it remains accessible in the RealSense SDK. A PDF file version of its documentation can be downloaded at the link below.
