The depth information from Kinect VS actual distance

Hi guys, I am quite new to ROS. What I've been trying to do is to obtain the depth data detected by Kinect in order to figure out how these data related to the actual distance.
The project I am using is Openni_Kinect. After launching it, I tried to get the depth information by using rostopic echo camera/depth/image as it provides Unrectified depth image with float depths in m. However, what I got is a huge amount of numbers like 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 75, 120, 148, 65, 75, 120, 148, 65, 75, 120, 148, 65, 75, 120, 148, 65...
So does anyone know what these number represent? Or am I doing it right? Do I need to switch to OpenNI to directly get the depth data?
Thanks in advance!
