rtabmap_ros kitti2rosbag using orb_slam2 as Odometry

edit

I successfuly run rtabmap_ros by rosbag created from kitti2rosbag .Thanks to Mathieu ! But now , when i try to us orb_slam2 as Odometry , i got a lot problems. I also successfully compiled RTAB-Map with Orb-Slam2, so I can now choose ORB-SLAM2 as an odometry strategy in RTAB-Map standalone app. And i try rtabmap_ros and add those code in launch:

<param name="Odom/Strategy" value="5"/>
      <param name="OdomORBSLAM2/VocPath" value="/home/harold/slam/SLAM/src/ORB_SLAM2/Vocabulary/ORBvoc.txt"/>
      <param name="OdomORBSLAM2/Bf" value="386.1448"/>
      <param name="OdomORBSLAM2/Fps" value="10"/>
      <param name="OdomORBSLAM2/ThDepth" value="35"/>

in

<node if="$(arg stereo)" pkg="rtabmap_ros" type="stereo_odometry" name="stereo_odometry" output="$(arg output)" args="$(arg rtabmap_args) $(arg odom_args)" launch-prefix="$(arg launch_prefix)">

Than i run

roslaunch rtabmap_ros rtabmap.launch stereo:="true" left_image_topic:=/kitti/camera_color_left/image_raw right_image_topic:=/kitti/camera_color_right/image_raw left_camera_info_topic:=/kitti/camera_color_left/camera_info right_camera_info_topic:=/kitti/camera_color_right/camera_info rtabmap_args:="--delete_db_on_start" approx_sync:=true use_sim_time:=true frame_id:=base_link
rosbag play --clock kitti_2011_09_26_drive_0001_synced.bag

Rtabmap only run a piture ,then it stop with:
