Hello,

I am trying to get the information from depthimage_to_laserscan, but I'm getting anything. That's what I'm doing:

1) roslaunch openni_launch openni.launch 2) rosrun depthimage_to_laserscan depthimage_to_laserscan image:=camera/depth/image_raw

Anything happens when I do that. When I type rostopic list, it appears the following topics among the others:

depthimage_to_laserscan/parameter_descriptions depthimage_to_laserscan/parameter_updates scan

I am using "ASUS Xtion PRO Live" and I am communicating ros with Matlab 2015a. I tried to subscribe to those topics, but there's no information being published.

I would really appreciate any help!

Thank you,

Vinícius
