Hi, We coded something doing that. You can find it here: https://code.launchpad.net/~ugocupcic/sr-ros-interface/opticaldataglove 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.
