Point Clouds Don't Appear In 3D Viewer

[bboyack]

I can get the demo to run perfectly, but when I try to run my own calibration, usually no point clouds will show up on the 3D viewer. Every now and then I'll see the point clouds, but not usually. Any suggestions of what may cause this issue?
Thanks in advance.

Hi @bboyack,
Can you please provide your config and data?
Best regards

I am using the calibration with live ouster lidars. I collected a ros2bag to share the data with you. Both the ros2bag and my config file can be located at https://byu.box.com/s/8wbx1b22fyi60wfbpjmf4exiar11a52h (let me know if the link doesn't work). Thanks for looking into this!

I just extracted a few .pcd files for each topic, but if I use your data, not even the visualization is working properly, but only if I use exclusively your data. If I just add one of the demo pcds, then I at least get a visualization, but of course the wrong calibration.
I just tried it with some arbitrary KITTI frames I had laying around and it still works as expected.

I'll have to take a closer look, but it certainly won't be before the weekend.

For reference, the frames I used from your data:

Very interesting and confusing. Thank you for looking at this again.

@ga58lar Have you been able to find anything out about this issue?
