Panorma Turtlebot

edit

I am working with the turtlebot 3 when i am using the function

rosservice call turtlebot3_panorama/take_pano 0 360.0 30.0 0.3

i never get 360 degree pictures but rather 180 degree Also when i select the panorama picture in rqt_image_view during the process of snapshot taking it seems to crash the process resulting in: at the end of panorama programm
