ros realsense D435i摄像头配置

之前在ubunut18中配置了ROS环境，现在需要在此基础上，配置D435i相机的SDK和ROS包。

一、参考

二、流程

1. 安装依赖
2. 安装SDK，使用版本V2.50.0
3. 安装ros包，对应最新版本
4. 运行测试

三、步骤

1. 依赖安装，有些可能是不必要的，没关系

sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade
sudo apt-get install -y git libssl-dev libusb-1.0-0-dev pkg-config libgtk-3-dev 
sudo apt install -y ros-melodic-ddynamic-reconfigure*
sudo apt-get install -y intel-realsense-dfu*
sudo apt-get install -y librealsense2-dev
sudo apt-get install -y librealsense2-dbg
sudo apt-get install -y librealsense2-dkms
sudo apt-get install -y librealsense2-utils

补充：

# 注册服务器公开密匙
sudo apt-key adv --keyserver keys.gnupg.net --recv-key F6E65AC044F831AC80A06380C8B3A55A6F3EFCDE || sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-key F6E65AC044F831AC80A06380C8B3A55A6F3EFCDE
# 将服务器加入仓库列表
sudo add-apt-repository "deb https://librealsense.intel.com/Debian/apt-repo bionic main" -u
# 库安装
sudo apt-get install librealsense2-dkms
sudo apt-get install librealsense2-utils

sudo apt-get install librealsense2-dkms
sudo apt-get install librealsense2-utils
sudo apt-get install librealsense2-dev
sudo apt-get install librealsense2-dbg  # （这个可以不安装）

2. 安装SDK

cd
git clone -b v2.50.0 https://github.com/IntelRealSense/librealsense.git
cd librealsense
mkdir -p build
cd build/
cmake ..
make -j8
sudo make install

补充，修改上述的后面内容

cd librealsense
./scripts/setup_udev_rules.sh													# Intel Realsense 权限脚本
./scripts/patch-realsense-ubuntu-lts.sh									# 构建和应用补丁内核模块
echo 'hid_sensor_custom' | sudo tee -a /etc/modules			# 驱动设置开机启动
cmake ../ -DCMAKE_BUILD_TYPE=Release -DBUILD_EXAMPLES=true		# 构建SDK
sudo make uninstall && make clean && make -j8 && sudo make install
# 最后如果报出了多个udev规则警告，运行如下
./scripts/setup_udev_rules.sh --uninstall

3. 安装ros包

cd
mkdir -p ~/catkin_ws/src
cd ~/catkin_ws/src/
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 ..
catkin_init_workspace
cd ..
catkin_make clean
catkin_make -DCATKIN_ENABLE_TESTING=False -DCMAKE_BUILD_TYPE=Release
catkin_make install

4. 测试

roslaunch realsense2_camera rs_camera.launch

rqt_image_view

5. 点云测试

roslaunch realsense2_camera demo_pointcloud.launch
roslaunch realsense2_camera rs_camera.launch filters:=pointcloud

获取/camera/depth_registered/points的相关内容，参考引用7的链接

6. 遇到一个问题，安装了该realsense 的ros包之后，与XTDrone的ego_planner的ros包出现冲突，无法共同存在。比如我现在只能删除realsense后，才能编译ego的包。
