如果已经创建过catkin_ws，直接cd过去就行
cd ~/catkin_ws/src
git clone https://github.com/RobustFieldAutonomyLab/LeGO-LOAM.git
cd ..
catkin_make -j1
source ~/catkin_ws/devel/setup.bash四、运行：
终端1:
roslaunch lego_loam run.launch终端2:
rosbag play YOUR_DATASET_FOLDER/nsh_indoor_outdoor.bag --clock --topic /velodyne_points /imu/data--clock使用BAG的时钟
