Hello,

I'm currently using kinect to receive image message and pointcloud2 message and make a depth and image with message information.

Then,I want to do some classification and label each pointcloud data and send back as ros message.

How should I have this label information??

One possible solution is to add a new field to the pcl::PointCloud datatype (that is, create a custom point type in PCL). There is a tutorial on how to do this on the PCL website: http://pointclouds.org/documentation/tutorials/adding_custom_ptype.php

Then, you would simply publish this new pointcloud with an additional custom label field.
