[narayanlongani]

Hello!
When I run roslaunch for the stereo calibration.... it runs fine
but when play the bag file having the topics
/stereo_camera/left/camera_info
/stereo_camera/left/image_rect_color
/stereo_camera/right/camera_info
/stereo_camera/right/image_rect_color
/velodyne_points

then .... REQUIRED process [planar_segmentation-11] has died!
process has died [pid 8684, exit code -11, cmd /home/a/vellcalibb/devel/lib/velo2cam_calibration/v2c_plane_segmentation ~input:=/stereo_camera/z_filtered_cloud __name:=planar_segmentation __log:=/home/a/.ros/log/6c3ce88c-a29b-11ed-81e3-88aedd1681ad/planar_segmentation-11.log].
