Hi, i'm new to RTAB-Map and ros. i follow the tutorial in how to use intel realsense R200 to do rtabmap. the robot i use is turtlebot3 with intel realsense R200 with ubuntu 16.04 (amd64) ros kinetic. i already run the realsense_camera R200_nodelet_rgbd.launch in the robot. the error i get are :

/rtabmap/rtabmap subscribed to (approx sync): /odom, /camera/rgb/image_rect_color, /camera/depth_registered/sw_registered/image_rect, /camera/rgb/camera_info, /scan

the display in rviz show nothing but black screen with blue green lines.

i have check the rostopic hz for each of the topic there. the results for /camera is a bit delayed like 1 - 3 no data then data received.

the launch file i use for rtabmap :

    <group ns="rtabmap">
      <node name="rtabmap" pkg="rtabmap_ros" type="rtabmap" output="screen" args="--delete_db_on_start">
