Warn messages occurred while launching calibration

[mingleeeeee]

Hi everyone, I got an warn error occurred while following everything on this e-manual.

http://emanual.robotis.com/docs/en/platform/turtlebot3/autonomous_driving/#tutorials-43-extrinsic-camera-calibration

Terminal code: $ roscore Step1 TurtleBot SBC: $ roslaunch turtlebot3_autorace_camera turtlebot3_autorace_camera_pi.launch Step2 TurtleBot SBC:

 $ export AUTO_IN_CALIB=action
 $ export GAZEBO_MODE=true ( I added it by myself )
 $ roslaunch turtlebot3_autorace_camera turtlebot3_autorace_intrinsic_camera_calibration.launch

Step3 Remote PC:

$ export AUTO_EX_CALIB=calibration
$ roslaunch turtlebot3_autorace_camera turtlebot3_autorace_extrinsic_camera_calibration.launch

After finish these steps, terminal in step2 got yellow warn messages... Turtlebot SBC:

[ WARN] [1532346786.215000834]: [image_transport] Topics '/camera/image_color' and '/camera/camera_info' do not appear to be synchronized. In the last 10s:
    Image messages received:      0
    CameraInfo messages received: 296
    Synchronized pairs:           0

Then the last step $ rqt Showed a pure white window without any information or image on it .

I also tried Tutorials: 5.1 Lane Detection , but my turtlebot did not move at all. It showed the same yellow messages

If there is any further information I need to show, please tell me. I would be as fast as I can.

Hi @harry21105 :) 'export GAZEBO_MODE=true' means that you run autorace in gazebo. But, I think you run autorace with actual turtlebot3 in real. So, you don't enter this command or enter follow command. export GAZEBO_MODE=false

Thanks, Gilbert.
