Hello,

I am using indigo version and I have been trying to convert the depth image to laser scan following this tutorial http://www.hessmer.org/blog/2011/04/1...

but I got the following error after executing "roslaunch ./launch/kinect_laser.launch" command

I think some files are missing, but I don't know how to fix it

That tutorial is over three years old, and is for ROS Diamondback.

Check out the sample launch files here: https://github.com/ros-perception/per...

And the parameter documentation here: http://wiki.ros.org/pointcloud_to_las...
