Re: [Ros-kinect] ROS, Kinect

What OS are you running? If you're a lucky Ubuntu user, you can just pull the binary packages (see
http://www.ros.org/wiki/ROS/Installation). Once you get ROS, you can:

$ rosrun pcl_tutorials pointcloud_online_viewer input:=/camera/points2

Provided that you simply ran the ROS driver as:

$ rosrun kinect_camera kinect_node

Then if you want to apply some filters from PCL, such as downsampling for example, do:

$ rosrun nodelet nodelet manager
$ rosrun nodelet nodelet load pcl/VoxelGrid manager /pcl_VoxelGrid/input:=/camera/points2
$ rosrun pcl_tutorials pointcloud_online_viewer input:=/pcl_VoxelGrid/output

You want to apply a Moving Least Squares smoothing algorithm to the input data so that it looks better? Surface
reconstruction? etc... it's all there, but you need to dig through the documentation/tutorials/examples ;)


Now if you do not want to run ROS (I cannot imagine why not, but whatever), and you want to get all these 3D operations
working in your C++ project, wait until next week (or help us do it faster) until PCL (http://pcl.ros.org) will
hopefully be available as a standalone library outside of ROS.

Cheers,
Radu.
