Using the ROS driver to get a point cloud and display it in rviz, what determines the colour of the different points of the point cloud? How can I read these specific values without going through DCA1000?

Hello,
The points are colored via "intensity" value. You can echo the rostopic that outputs the pointcloud information and each point will have this intensity setting. We now traditionally call this value the Signal-to-Noise ratio (SNR), with a larger number representing a stronger reflection.
