How do you use depth_image_proc?
Since there is no tutorial for this, how do I use these nodelets to convert a Kinect depth image into a PCL point cloud?
kinect -> point_cloud_xyz -> cloud
or do I need to use convert_metric?
kinect -> convert_metric -> point_cloud_xyz -> cloud
and if I want and xyzrgb pcl cloud (note this is a simplification and I don't know if I need convert_metric)
kinect -> register -> point_cloud_xyzrgb -> cloud
I would greatly appreciate an example roslaunch file if anyone has it. Thanks
