Hi, what exactly do u mean it's not working, does it give you a specific error? does it have no output?

Here are a few common errors people do while using this tutorial:

• forgetting to run roscore (very common mistake for beginners).

• do not source their files (making ros unable to recognize it as a stack/package)

• use input:=/narrow_stereo_textured/points2 even though that input is specific to a certain type of camera which might not be yours. What kind of camera are you using? If it's a kinect for example then you would want to use input:=camera/depth_registered/points

• Are you trying to one for Point Clouds or Point Clouds 2? The one for Point Clouds does not publish images you can view, while the one for Point Clouds 2 publishes a message of type Point Clouds 2 (if you are trying to view it in rviz make sure that's the type you have chosen to view it).

If none of these are your problem then please give us some more information so that we may be able to understand your problem better.
