I'm having trouble viewing a kinect image in RViz. Today, the same rviz config file that has worked in the past did not work. I thought there may be a problem with rviz, so I uninstalled and reinstalled it. That may be part of the problem.
System:
- ros hydro on ubuntu 12.04
- rviz version 1.10.20 compiled against OGRE version 1.7.4 (Cthugha)
- Video card (from
lspci):NVIDIA Corporation GK106 [GeForce GTX 645 OEM] (rev a1) - using kinect v1 with
openni_launchdriver
Steps taken:
- Click Add, select Image
- Set topic to
/yellow_kinect/rgb/image_color
Result:
- Image status is "Ok"
- Number of frames is incrementing normally
- No image shown -- just black pixels in the image panel
Other things tried:
- Tried using the
Cameradisplay type in my RViz, instead ofImage. This does not work either (it's an all-white image).
Sanity checks:
rosrun image_view image_view image:=/yellow_kinect/rgb/image_color-- When I do this, I see the live image, not black.- I confirmed that RViz and the kinect are both talking to ros master on the same machine (my robot)
- When I try the same thing from another computer in my lab, the image shows up correctly in RViz.
I think it's an issue with the state of ROS or RViz on my desktop. I was using RViz constantly with the same system setup for weeks. Then I wasn't using it for a few weeks, and now it's broken.
Any suggestions on how to make RViz display the camera images would be greatly appreciated!

Can you try using a Camera display type? I would expect the image to work. What video card are you using? (note: Hydro is no longer supported so if it is a bug we'll probably not release it into binaries)

Is this Kinect v1 (aka Kinect for Xbox 360) or Kinect v2 (Kinect for Xbox One)? Also which library are you using?

It's Kinect v1 and openni_launch

Maybe you can have a look at the header of the received images. Is everything "normal" there? (incrementing sequence number, time stamps etc.) I remember having troubles with Rviz due to corrupt header information.
