更新一下
sudo apt-get -f install
sudo apt-get update
如果发生apt-get upgrade或sudo apt-get update错误:
wget -q -O - http://dl.google.com/linux/linux_signing_key.pub | sudo apt-key add -
sudo apt-get upgrade
sudo apt-get install ros-kinetic-velodyne
注意:kinetic换成你自己的版本比如indigo

rosdep update
//这里我已经安装gtsam库了,就跳过了
//rosdep install --from-paths src --ignore-src --rosdistro YOURDISTRO -y
//第一次一定要带 -j1
catkin_make -j1
source devel/setup.bash
在官网下载VLP-16.xml,放在桌面
//转换成yaml格式
rosrun velodyne_pointcloud gen_calibration.py ~/Desktop/VLP-16.xml
roslaunch velodyne_pointcloud VLP16_points.launch calib:="~/Desktop/VLP16.yaml"
//然后在rviz中点Add,增加PointCloud2,再在PointCloud2下点topic输入/velodyne_points。这样就可以实时显示获取的3D点云图。
rosrun rviz rviz -f velodyne
//只保存/velodyne_points这个topic的数据(可以用rostopic list -v开看当前可用的topic),保存在当前目录的out.bag
rosbag record -O out /velodyne_points

//启动激光雷达节点
roslaunch velodyne_pointcloud VLP16_points.launch calib:="~/Desktop/VLP16.yaml"
//开始跑slam,会自动打开rviz
roslaunch lego_loam run.launch
或者跑本地数据:

//卸载:
sudo dpkg -r package_name
//注意,卸载时候是package_file.deb对应的package name,若不知道package name,可以通过
dpkg -l查找,若要查找对应的package,可以加通配符,如查找包含fox的package
dpkg -l fox即可
//查到以后,可以运行
dpkg -r package_name卸载
