how to get and read the data from kinect
I need to use the data from kinect,and i have installed the stack openni_kinect;so if i want to get and read the data from kinect,should i need to create a node to publish the relative messages? and how should i create? Or is there another way to complete it? In addition i did not find any information about "publisher" or "service" in the stack openni_kinect. note:Ubuntu11.10 ROS electric Thank you very much!
