I've posted it as camera_umd/uvc_stereo in git://ram.umd.edu/umd-ros-pkg.git. It still needs some changes to the underlying driver to make synchronization work properly, but it should get close as it is. If your cameras don't have big exposure-related shutter-speed changes like mine sometimes do (taking them out of sync), it will broadcast synchronized pairs well.

uvc_stereo broadcasts matched pairs of images:

  * to /{left,right}/{image_raw,camera_info}

  * using camera_info_manager and uvc_cam's driver

  * with support for rotated (180 degrees) cameras

It doesn't yet support:

  * reading or broadcasting JPEG streams from the cameras

  * working in anything but RGB8

  * setting camera parameters by dynamic_reconfigure or message streams

Docs soon at http://www.ros.org/wiki/uvc_stereo
