Hi,
We coded something doing that.
You can find it here:

I used usb_cam to publish images from the webcam. Then, the synchroniser
node is in optical_synchronizer.
It's still really experimental so you may have to modify things a bit
for it to work. If you need more info don't hesitate to contact me.
Cheers,
Ugo
