2013-01-03 10:03:03 -0500	commented answer	PCL-ROS run time error while doing plane segmentation. Except that the code you posted says `downsampled_XYZ->width = 15; ...` and I still don't see where you call `new sensor_msgs::PointCloud2` anywhere.
2013-01-03 04:50:48 -0500	answered a question	PCL-ROS run time error while doing plane segmentation. If you haven't figured it out already (or it's an omission in your code copying), it looks like the `downsampled` cloud pointer has not been initialized with a valid cloud. You pass the dereferenced shared pointer in the `sor.filter(downsampled)` line... At some point, you need: `downsampled.reset(new sensor_msgs::PointCloud2)` In addition, the output cloud pointer has not been initialized, so the call to `pcl::toROSMsg(output_p, *output)` will also generate an error. If that is not the problem, you'll probably have to provide some more information (like a backtrace from gdb or something)... Hope this helps.
