A few quick things
1) I can use it with rviz. Jack, I'll shoot you an email tomorrow with
the rviz config that I use. Remind me if I forget.
2) My driver started as a port from Player, but I've replaced and added
a lot of functionality (e.g. Bayer filtering) with built-in libdc1394
functions.
3) Jack, once you get into this, I might bend your ear to help me do the
same for a unified Swissranger 3000/4000 driver. I have a version that
I expanded from Rasu's 3K driver that adds new functionality for 4K
devices. I also have a color camera/pointcloud registration node )with
calibration utility) that would probably go in this stack (but could be
used for stereo cameras). I haven't looked around recently to see if
others exist, but I don't remember seeing anything that worked in ros
>=0.9 several months back.
