I calibrated my camera using /rosbuild_ws/package_dir$ rosrun camera_calibration camacalibrator.py --size 8x5 --square 0.030 image:=/usb_cam/image_raw --no-service-check command. It wrote on the terminal screen below output :

Which ones should I use this information to run rosrun lsd_slam_core live_slam /image:=<yourstreamtopic> _calib:=<calibration_file>? I use ros-indigo.
