Short answer, I don't know. > The reason I ask this is that, if you use the cameras on a robot and > you're trying to extract depth information from the two images and the > robot is moving, having two unsynchronized images is pretty much useless. > > However, if they are synchronized, this would make a nice low cost > robotic stereoscopic vision system... Still short answer, try it :-) UVC devices send timing information along with video data. This can be used to synchronize the device internal clock with the host clock. The UVC driver doesn't implement that feature, and I'll be happy if someone wants to give it a go and submit a patch.
