IEEE1588 Simplifies Camera Synchronization

April 19, 2017

 

Arriving at the office this morning, and flipping through reading material (in paper format yes), I glanced at this month’s copy of Vision Systems Design (April 2017), and saw an article in there on synchronization down to 1nS with just the plain Ethernet cable already hooked to the camera.

 

One camera is defined as the master clock and then the other cameras synchronize their times to that one.  So the trick is which cameras are currently capable of this feature and how do you set it up. It looks like we are still on the early side of implementation, but GigE Vision standard 2.0 has some features associated with it, and also for the master clock it looks like some specialized equipment is required. The specialized equipment can be substituted for a Linux PC and some ‘free’ Grand Master software, which usually implies setup effort.

 

Looks like it is early on implementation, but promises to give cross camera synchronization with a very small price tag in terms of setup and integration. Looking forward to it.
