xyzrgb point cloud freezes in rviz after displaying for 1 second about realsense-ros HOT 11 CLOSED

By crash to you mean rviz stops streaming? Please confirm this is what you are seeing.

If yes, we could reproduce this and it will be investigated further.

Yes, it stops streaming. If I select the other point cloud topic it starts streaming again without rgb, but won't start rgbxyz point cloud stream again.

We experienced a very similar behavior on a Ubuntu machine with an identical configuration as the one above except on Indigo. Sporadically we were able to get a single (or very few) colored point cloud message(s). In rviz, this lead to the behavior described above.
We also tested it on an OSX 10.11 machine running Jade where we got no colored point cloud at all.

@jgoppert Could you check if PR #38 helps in your case?

from realsense-ros.

@jgoppert Have you tried release 1.0.4? Did that resolve the issue?
If not, can you please add your system configuration information: CPU, Memory, type of storage (disk/emmc/sdcard...)

from realsense-ros.

@mdhorn @mrshpot fixed for me on 1.0.4

from realsense-ros.

Great!

@mdhorn This seems to be back on latest master of realsense-ros and librealsense

Experiencing this issue in realsense ros 1.5.0 and librealsense 1.11.0. Depth_registered/points stream freezes after a second. No Warns or Errors from Rviz.

@betaupsx86
Can you please provide the details of your platform: processor, memory, local storage type (SSD, HD, etc)?

I'm attaching a patch to set the message filter to use exact instead of approximate. Please give this a try on your system.

There seems to be small periodic frame drops in the IR streams. I actually went back to realsense 1.4 and now I'm experiencing the same issue. With that version everything used to work fine.
