注意：realsense-ros 要和 librealsense 版本匹配，realsense-ros 2.2.7 对应的 Realsense SDK 为 librealsense 2.24 .0
1. 源码安装 librealsense
参考：https://github.com/IntelRealSense/librealsense/blob/master/doc/installation.md
更新系统
sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade
下载源码
git 下载
git clone -b v2.24.0 https://github.com/IntelRealSense/librealsense.git
或手动下载：https://github.com/IntelRealSense/librealsense/archive/master.zip
安装依赖，若有 realsense 连接，先unplug
sudo apt-get install git libssl-dev libusb-1.0-0-dev pkg-config libgtk-3-dev
sudo apt-get install libglfw3-dev
安装包根目录，run Intel Realsense permissions script
./scripts/setup_udev_rules.sh
Download, patch and build realsense-affected kernel modules (drivers)
./scripts/patch-realsense-ubuntu-lts.sh
编译安装
mkdir build && cd build
cmake ../ -DCMAKE_BUILD_TYPE=Release -DBUILD_EXAMPLES=true
sudo make uninstall && make clean && make -j8 && sudo make install
The shared object will be installed in /usr/local/lib, header files in /usr/local/include.
The binary demos, tutorials and test files will be copied into /usr/local/bin
2. 源码编译 realsense-ros
创建工作空间
mkdir -p ~/catkin_ws/src && cd ~/catkin_ws/src
下载源码，并检查依赖
git clone -b 2.2.7 https://github.com/IntelRealSense/realsense-ros.git cd realsense-ros/realsense2_camera git checkout `git tag | sort -V | grep -P "^d+.d+.d+" | tail -1`
sudo apt-get install ros-kinetic-ddynamic-reconfigure
编译
cd ~/catkin_ws
catkin_make clean catkin_make -DCATKIN_ENABLE_TESTING=False -DCMAKE_BUILD_TYPE=Release catkin_make install echo "source ~/catkin_ws/devel/setup.bash" >> ~/.bashrc source ~/.bashrc
启动相机节点
roslaunch realsense2_camera rs_camera.launch
