rtabmap_ros how to set odometry and camera?

edit

Hello

i try to xtion, kobuki(2 wheel mobile robot).

i read http://wiki.ros.org/rtabmap_ros/Tutor... .

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.

<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"/>

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.
