Does anybody know how to synchronize video recording on multiple RPi systems with a RPi cam each?
I want to experiment with motion capture using 2 (or more) video camera's.
Camera's will be about 3 meter apart, connect by wired ethernet. Subject is a 40 mm white ball at 1..5 meter distance from the camera's, moving at a maximum speed close 100 km/hr.
Probably a third, more powerful, computer will store all video on disk, do 3D tracking and visualisation, be the source for synchronisation and remote control.
There are plenty of items to solve, but has somebody information about questions :
a) can the video driver (v4l / RPi-driver) handle synchronised recording at frame level from an extenal trigger? (a program that signals the driver to get the next frame)
b) does or can the video stream (or file) contain time stamps (data, not video image)
