I am using 'elp_stereo_camera'. (ubuntu 14.04, indigo) I can not get the camera image on the rviz main display. but I can see the preview on the bottom of the left side view.

please check the link below.

I successfully install all things and tried to launch.

# terminla 1

# terminal 2
roslaunch elp_stereo_camera elp_stereo_camera.launch

# terminal 3
roslaunch elp_stereo_camera stereo_image_proc.launch

# terminal 4
roslaunch elp_stereo_camera rviz.launch

At first, the terminal 3 shows,

[ERROR] [1492750361.750198731]: Rectified topic '/elp/right/image_rect' requested but camera publishing '/elp/right/camera_info' is uncalibrated

So I did calibration, and now it shows

[elp/stereo_image_proc-1] process has died [pid 6174, exit code -6, cmd /opt/ros/indigo/lib/stereo_image_proc/stereo_image_proc __name:=stereo_image_proc __log:=/home/sophie/.ros/log/ee59129a-2651-11e7-85f4-0022cffa2d4b/elp-stereo_image_proc-1.log].
log file: /home/sophie/.ros/log/ee59129a-2651-11e7-85f4-0022cffa2d4b/elp-stereo_image_proc-1*.log

Please help me which part I need to check.. Thank you.image description
