How to get RGB values out of RVIZ PointCloud2 or Markers? [closed]
I'm on the latest ROS groovy for Ubuntu 12.04 LTS. I want to be able to view a point or marker's numeric RGB value (instead of just showing the color). When I select a PointCloud, it shows rgb as 0;0;0 for non black dots. And markers display no value.
Is there a way to get these values?
