[ros-users] custom stereo cams

[Ugo Cupcic]

 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
