Cannot visualize PointCloud2 topics through rviz or openni_viewer

Hi,

I'm trying to visualize /points2 topic through rviz or openni_viewer. Even though I'm getting average rate: 2.989 min: 0.193s max: 0.759s std dev: 0.08753s window: 34, it will not show up in the visualization.

I used rosrun pclros convertpointcloudtoimage input:=/points2 output:=/test then rosrun imageview imageview image:=/test to test that pointcloud topic works and I can see the image...

What am I doing wrong so that I cannot visualize the pointcloud through rviz or openni_viewer?

Rviz: no errors, just white dot in the middle. Openni_viewer: just blank

Thank you

The first thing I would check would be your and settings in Rviz to make sure that you aren't trying to view a tf frame that does not exist. You need to have the proper tf published to view your cloud properly.

For rviz I did rosrun tf static_transform_publisher 0 0 0 0 0 -1.57 base camera 100 to set static coordinate, but it shouldn't matter for openni_viewer right? Openni_viewer visualized the pointcloud fine when I used my webcams without the tf.
