Hello
i try to xtion, kobuki(2 wheel mobile robot).
i read http://wiki.ros.org/rtabmap_ros/Tutorials/SetupOnYourRobot.
and apply my launch.
i modify rgbd_mapping.launch.and program work normally.
<arg name="subscribe_scan" default="true"/> <!-- Assuming 2D scan if set, rtabmap will do 3DoF mapping instead of 6DoF -->
<arg name="scan_topic" default="/kinect_scan"/>
<arg name="subscribe_scan_cloud" default="false"/> <!-- Assuming 3D scan if set -->
<arg name="scan_cloud_topic" default="/scan_cloud"/>
<arg name="visual_odometry" default="false"/> <!-- Generate visual odometry -->
<arg name="odom_topic" default="/odom"/> <!-- Odometry topic used if visual_odometry is false -->
<!-- Kinect cloud to laser scan 11cm 16cm-->
<node pkg="depthimage_to_laserscan" type="depthimage_to_laserscan" name="depthimage_to_laserscan">
<remap from="image" to="/camera/depth_registered/image_raw"/>
<remap from="camera_info" to="/camera/depth_registered/camera_info"/>
<remap from="scan" to="/kinect_scan"/>
<param name="range_max" type="double" value="4"/>
</node>
<node pkg="tf" type="static_transform_publisher" name="odom_camera_tf" args="0.11 0 0.16 0 0 0 1 /base_footprint /camera_link 100" />
but result is strange.
first. set my xtion from robot ( 0.11cm, 0, 0.16cm) so i add tf broadcaster.
result is below link.

1.point cloud and map cloud is different.
is the result normal??
2.map is bad when robot turn a round and go to origin.
