一、安装RealSense SDK

1、RealSense SDK源码下载

 2、安装依赖库

3、编译与安装

二、安装pyrealsense2

三、安装Realsense_ros

---

因为课题需要使用D435i获取深度信息，所以要使用pyrealsense2这个python包。在安装过程中也踩了很多坑，所以这一篇文章专门来说一下Jetson Xavier NX安装Librealsense2 SDK、pyrealsense2和Realsense_ros，其实我们只需要安装完Librealsense2 SDK后配置一下环境就可以使用Python3.6中的pyrealsense2了。

一、安装RealSense SDK

RealSense SDK已经可以直接在Jetson Xavier NX上进行安装，其安装方式有两种，一个是从源码编译安装，一个是直接apt-get安装。但是apt-get安装虽然便捷，但是一定不会成功，我看到其他博主也是没有成功，所以我就不在这个说apt-get安装的过程了。

1、RealSense SDK源码下载

首先从官网下载RealSense SDK源码：Releases · IntelRealSense/librealsense (github.com)

我下载的是v2.48.0版本的，因为后面安装的 Librealsense_ROS 要和 RealSense SDK 的版本想比配，比v2.48.0高的版本所对应的 Librealsense_ROS 都是需要ROS2来匹配。

 2、安装依赖库

sudo apt-get install git libssl-dev libusb-1.0-0-dev pkg-config libgtk-3-dev libeigen3-dev 
sudo apt-get install libglfw3-dev

3、编译与安装

进入解压好的源码文件，在新建的build文件夹下进行编译与安装

cd librealsense-2.48.0
mkdir build
cd build
cmake ../ -DFORCE_RSUSB_BACKEND=ON -DBUILD_PYTHON_BINDINGS:bool=true -DPYTHON_EXECUTABLE=/usr/bin/python3.6 -DCMAKE_BUILD_TYPE=release -DBUILD_EXAMPLES=true -DBUILD_GRAPHICAL_EXAMPLES=true -DBUILD_WITH_CUDA:bool=true
sudo make uninstall
sudo make clean
make -j4
sudo make install

检查目录/etc/udev/rules.d/下是否有99-realsense-libusb.rules文件，如果没有需要手动生成文件99-realsense-libusb.rules，复制内容如下，如果没有这个文件可能摄像头的imu打不开。

最后，执行realsense-viewer如果能正确显示摄像头采集图像界面，则证明SDK库已成功安装。

二、安装pyrealsense2

pyrealsense2是我们在使用python调用摄像头时候会用到的一个包，其实我们前面安装RealSense SDK的时候就已经安装完pyrealsense2了，所以这里只需要输入以下的代码添加到路径中即可。

sudo gedit ~/.bashrc

export PATH=$PATH:~/.local/bin
export PYTHONPATH=$PYTHONPATH:/usr/local/lib
export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python3.6/pyrealsense2

source /.bashrc

到这里就已经可以在python3中调用pyrealsense2了，输入以下代码不再提示"No Mudule Named Pyrealsense2"错误信息，则证明pyrealsense2已安装成功。

python3
import pyrealsense2

三、安装Realsense_ros

Realsense官方提供的安装方式依旧有两种，一个是从源码编译安装，一个是直接apt-get安装ros包，同样我们还是只用源码编译的方式。通过下面这个网址我们可以查询到我们安装的RealSense SDK版本所对应的Realsense_ros，我下载的版本是realsense-ros-2.3.1。

Releases · IntelRealSense/realsense-ros (github.com)

同时我们还要下载ddynamic_reconfigure

下载地址：GitHub - pal-robotics/ddynamic_reconfigure

进入终端输入以下命令

mkdir -p ~/catkin_ws/src
cd ~/catkin_ws/src/

把我们刚才下载好的realsense-ros-2.3.1和ddynamic_reconfigure-kinetic-devel都放入到src文件夹后，在终端中输入以下命令

catkin_init_workspace
cd ..
catkin_make clean

这里可能会遇到以下错误

错误1：

 根据这个报错的提示，可以看出是: “cv_bridge” 的路径问题。我们可以通过/opt/ros/melodic/share/cv_bridge/cmake路径打开cv_bridgeConfig.cmake文件

cd /opt/ros/melodic/share/cv_bridge/cmake/
sudo gedit cv_bridgeConfig.cmake

找到第96行，这里就是cv_bridge的路径

 修改路径并保存即可

set(_include_dirs "include;/usr/include;/usr/include/boost/compute/interop/opencv")

错误2：

fatal error: opencv2/core/core.hpp: No such file or directory
        #include 

错误原因其实就是，他找的opencv2并不在usr/include里，我们可以进入到usr/include查看，发现在的东西叫opencv4，并且opencv2在opencv4文件夹中，所以我们直接在终端里输入下面的命令软链接过去即可

sudo ln -s /usr/include/opencv4/opencv2 /usr/include/opencv2

catkin_make clean完成以后继续执行以下命令

catkin_make -DCATKIN_ENABLE_TESTING=False -DCMAKE_BUILD_TYPE=Release
catkin_make install

下面把他添加到环境变量里

echo "source ~/catkin_ws/devel/setup.bash" >> ~/.bashrc
source ~/.bashrc

到这里就彻底完成了，运行下面的命令检测一下

roslaunch realsense2_camera rs_camera.launch

会出现很多的话题，像这样就是就是安装成功了。
