Intel Realsense D455深度相机的标定及使用(一)——安装librealsense SDK2.0以及realsense-ros

一、安装Intel® RealSense™ SDK 2.0

         Intel® RealSense™ SDK 2.0 的DKMS内核驱动包(librealsense2-dkms)支持Ubuntu LTS内核版本4.4、4.8、4.10、4.13、4.15、4.18、5.0、5.3、5.4。

        1.1 查看自己的内核版本:

sudo cat /proc/version

        如果非上述版本,需要手动安装和修补版本,请移步官网教程:https://github.com/IntelRealSense/librealsense/blob/master/doc/distribution_linux.md

本教程不适合你。

        1.2 注册服务器公钥:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-key F6E65AC044F831AC80A06380C8B3A55A6F3EFCDE || sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-key F6E65AC044F831AC80A06380C8B3A55A6F3EFCDE

        如果公钥无法检索,检查并指定代理设置:

export http_proxy="http://:"

        重新运行该命令。

        1.3 将服务器添加到储存库列表

sudo add-apt-repository "deb https://librealsense.intel.com/Debian/apt-repo $(lsb_release -cs) main" -u

        1.4 安装库

sudo apt-get install librealsense2-dkms
sudo apt-get install librealsense2-utils

        上面两行代码将部署librealsense2 udevs规则,构建和激活内核模块、运行库和可执行演示和工具包。

        1.5 可选择安装开发人员和调试包:

sudo apt-get install librealsense2-dev
sudo apt-get install librealsense2-dbg

        1.6 验证内核是否已经更新:

modinfo uvcvideo | grep "version:"

         version后面出现realsense表示更新成功。

        1.7 启动realsense-viewer

        插入D455相机,可能需要USB3.0及以上接口。启动realsense-viewer:

realsense-viewer

        通过界面左侧的选项可以打开imu,双目和rgb相机模块,右上可切换2D、3D界面:

         成功!退出realsense-viewer界面。

二、realsense-ros的安装与编译

        2.1 创建工作空间

       创建工作空间 ,这里~/Packages/RealsenseRos_ws可以自定义路径,但必须包含/src:

mkdir -p ~/Packages/RealsenseRos_ws/src

cd ~/Packages/RealsenseRos_ws/src

         2.2 从github上下载realsense-ros并修改指针:

git clone https://github.com/IntelRealSense/realsense-ros.git
cd realsense-ros/
git checkout `git tag | sort -V | grep -P "^2.\d+\.\d+" | tail -1`
cd ..

        2.3 安装ddynamic_reconfigure

        初始化工作空间前,最好检查一下ddynamic_reconfigure是否安装。

        执行如下命令(注意将melodic改为自己的ROS对应版本,修改“melodic”为"kinect"、"neotic"等等):

sudo apt-get install ros-melodic-ddynamic-reconfigure

        否则会出现报错:提示没有ddynamic_reconfigure。

        2.4 初始化工作空间       

catkin_init_workspace
cd ..
catkin_make clean

        2.5 安装源码

catkin_make -DCATKIN_ENABLE_TESTING=False -DCMAKE_BUILD_TYPE=Release
catkin_make install

        2.6 添加工作路径到bashrc文件

        注意修改~/Packages/RealsenseRos_ws/为自己的路径。

echo "source ~/Packages/RealsenseRos_ws/devel/setup.bash" >> ~/.bashrc
source ~/.bashrc

        2.7 插上相机并启动相机

        插上相机运行

roslaunch realsense2_camera rs_camera.launch

        如果出现报错:[camera/realsense2_camera_manager-2]进程已经死亡。报错如下:

/opt/ros/melodic/lib/nodelet/nodelet: symbol lookup error: /home/khz/ROS/catkin_ws/devel/lib//librealsense2_camera.so: undefined symbol: _ZN2cv3MatC1EiiiRKNS_7Scalar_IdEE

log file: /home/khz/.ros/log/81b1e24a-8f95-11ec-8270-344b50000000/camera-realsense2_camera-3*.log

        如下图:

         由于出现提示:未定义标识符undefined symbol: _ZN2cv3MatC1EiiiRKNS_7Scalar_IdEE。猜测是OpenCV库的问题。

        解决方案:

        首先看看自己有没有安装OpenCV,没有安装请先安装,安装过程略。

        如果已经安装,打开realsense-ros的功能包文件夹下 realsense2_camera 文件夹下的 CmakeLists.txt文件,做出如下修改:

        添加set(OpenCV_DIR /usr/local/share/OpenCV/)到find_package前(下图11行,注意检查自己OpenCV的路径),添加OpenCV REQUIRED到find_package里(下图26行,注意放在括号里)。

         添加${OpenCV_LIBS}到目标链接库里(下图127行)

         然后跳回2.5再次安装,完成后执行roslaunch realsense2_camera rs_camera.launch。看到如下图就是启动成功了(有Realsense Node Is Up就行,警告可以忽略)。

         2.8 启动RGBD相机

        如果是RGBD相机,需启用第二步验证:

roslaunch realsense2_camera rs_rgbd.launch

        如果出现报错:

Resource not found: rgbd_launch
ROS path [0]=/opt/ros/melodic/share/ros
ROS path [1]=/home/andyvictory/Packages/RealsenseRos_ws/src
ROS path [2]=/opt/ros/melodic/share
The traceback for the exception was written to the log file

        安装RGBD的launch(注意ROS版本):

sudo apt install ros-melodic-rgbd-launch

        安装成功!
