Question

Hi, i use kinect and i want to convert depthimage to laserscan. i create this file.launch:

<launch>
    <arg name="camera"  default="camera"/>
    <arg name="publish_tf" default="true"/>
    <group if="$(arg scan_processing)">
        <node pkg="nodelet" type="nodelet" name="depthimage_to_laserscan" args="load depthimage_to_laserscan/DepthImageToLaserScanNodelet $(arg camera)/$(arg camera)_nodelet_manager">
        <param name="scan_height" value="10"/>
        <param name="output_frame_id" value="/$(arg camera)_depth_frame"/>
        <param name="range_min" value="0.45"/>
        <remap from="image" to="$(arg camera)/$(arg depth)/image_raw"/>
        <remap from="scan" to="$(arg scan_topic)"/>
</launch>

I receive this error:

Invalid roslaunch XML syntax: mismatched tag: line 11, column 2 The traceback for the exception was written to the log file

What can i do please?

You are missing the group closing XML tag:

<launch>
    <arg name="camera"  default="camera"/>
    <arg name="publish_tf" default="true"/>
    <group if="$(arg scan_processing)">
        <node pkg="nodelet" type="nodelet" name="depthimage_to_laserscan" args="load depthimage_to_laserscan/DepthImageToLaserScanNodelet $(arg camera)/$(arg camera)_nodelet_manager">
        <param name="scan_height" value="10"/>
        <param name="output_frame_id" value="/$(arg camera)_depth_frame"/>
        <param name="range_min" value="0.45"/>
        <remap from="image" to="$(arg camera)/$(arg depth)/image_raw"/>
        <remap from="scan" to="$(arg scan_topic)"/>
    </group>   <!-- You are missing this!! -->
</launch>

Is that related with this question at all? If not, close this question (accepting the answer or if it does not solve the problem you report will have to give more info) and create a new one..
