Hello,

Has anyone tried the new Asus Xtion Pro Live RGB-D camera (http://us.estore.asus.com/index.php?l=product_detail&p=4001) with the ROS openni drivers? In particular, how close to the camera can one get a depth image? I think the Kinect is only good to within about 2 feet of the camera which means it can't be used to get depth information for objects closer than that. So I am wondering if the Asus is any better in this regard.

Thanks!

Patrick,

The Xtion is a lot nicer in terms of weight/size/mounting possibilities. However, it won't reduce the minimum range (optics are pretty similar to the kinect/primesense devices). I'm also not sure if our drivers work 100% yet with that device (the one I had wandered off to another office last week).

Thanks Fergs,

Yeah, that all looks very appealing, though I was hoping for closer range depth info. Not that I need it right now, but it would be nice sometimes to be able to mount the camera closer in to the workspace. Perhaps I'll get to use my Videre STOC camera some day after all. ;)

A slight improvement to Kinect is coming:

Of particular interest to developers will be the new firmware which enables the depth camera to see objects as close as 50 centimeters in front of the device without losing accuracy or precision, with graceful degradation down to 40 centimeters.

I thought I would just add that the Pro Live works just fine with the ROS OpenNI drivers (I've recently switched Maxwell over to a Pro Live, and had no issues).

Interesting--too bad one of the improvements isn't to run solely off a USB port like the Asus; i.e. without the need for an additional power source.

Another improvement it needs is to weigh less, like the Asus.

Definitely. I monitored the temperature of an AX-12 holding the Kinect at about 20 degrees downward and it climbed toward 60 degrees within about 20 minutes. And I gutted the Kinect's motors from that one so it was even lighter.
