Revision history [back]

Well I solved it like this:

1.- cd to the /sandbox directory that has been created by rosws
2.- Add the repository to the overlay, e.g. it is added to ~/working_space/sandbox/.rosinstall

    rosws set  -y depthimage_to_laserscan  --git https://github.com/ros-perception/depthimage_to_laserscan.git 

3.- update the rosws
    rosws update depthimage_to_laserscan
4.- source ~/.bashrc 
5.- cd to depthimage_to_laserscan and run cmake . and make

The launch file may look like this:

<launch>
<node pkg="depthimage_to_laserscan" type="depthimage_to_laserscan" name="depthimage_to_laserscan" args="image:=/camera/depth/image_raw" respawn="true"> 
   <!--param name="output_frame_id" value="/camera_depth_frame"/-->
   <param name="scan_height" value="290"/> 
    <param name="scan_time" value="0.125"/>
    <param name="range_min" value="0.80"/>
    <param name="range_max" value="3.0"/>
    <param name="min_height" value=".10"/>
    <param name="max_height" value="2.0"/>
    <remap from="/scan" to="/scan_xtion"/>  
</node>
</launch>

Then run:

rosrun rviz rviz and the fake kinect can be seen under the topic /scan_xtion

Cheers
