I tried to run lsdslam on my laptop.all required packages were compiled smoothly. However, when typing `rosrun lsdslamcore liveslam image:=/ardrone/front/imagerect camerainfo:=/ardrone/front/camera_info`

segmentation fault(core dumped) was found in the terminal. I am new to ROS, so does anyone tell me how to fix this problem? I do find these topics when running rostopic list.
