Multiple subscribed topics in one callback
Hi, I'm new to ROS and PCL as well so please excuse my trivial question.
I need to process a PointCloud topic and CameraInfo topic (project the cloud using the camera info). What is the best way to do that? I can see that I cannot have multiple topics as arguments in one callback, I found I can use the function "bind" but I am not sure if it is the right way for me...
Thanks in advance, jp
