d435i+librealsense+realsense_ros在Ubuntu16.04上的安装

ubuntu16.04下安装librealsense和realsense_ros一次过关

首先感谢这几个网站

1. 安装教程
2. 官方

这里主要参照1

# 首先是
sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade

更新完Ubuntu之后开始下载librealsense

# 下载librealsense 2.48.0， 目前的最新版
git clone https://github.com/IntelRealSense/librealsense.git
#进入目录并安装一些package
cd ~/librealsense
git checkout v2.48.0
sudo apt-get install git libssl-dev libusb-1.0-0-dev pkg-config libgtk-3-dev 
sudo apt-get install libglfw3-dev
sudo cp config/99-realsense-libusb.rules /etc/udev/rules.d/ 
sudo udevadm control --reload-rules && udevadm trigger
./scripts/patch-realsense-ubuntu-lts.sh

一路下来就好，这里原博主说可能遇到问题，这里遇到问题的参照安装教程，后面直接build

cd ~/librealsense
mkdir build && cd build
cmake ../
cmake ../ -DBUILD_EXAMPLES=true
sudo make uninstall && make clean && make && sudo make install
#这里不出错就编译好了，然后直接
realsense-viewer
#就可以看到结果了hhh

后面有一系列更新的，我这里没有做也没有影响成功安装，后面直接开始介绍realsense_ros的安装

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

这里可能会遇到错误，类似这种

Could not find a package configuration file provided by
"ddynamic_reconfigure" with any of the following names:

# 直接
 sudo apt-key adv --keyserver 'hkp://keyserver.ubuntu.com:80' --recv-key C1CF6E31E6BADE8868B172B4F42ED6FBAB17C654
 sudo apt-key del 421C365BD9FF1F717815A3895523BAEEB01FA116
 sudo apt-get update
 sudo apt-get install ros-kinetic-ddynamic-reconfigure
# 然后再
catkin_make clean
#就可以了
#最后就是
catkin_make -DCATKIN_ENABLE_TESTING=False -DCMAKE_BUILD_TYPE=Release
catkin_make install
echo "source ~/catkin_ws/devel/setup.bash" >> ~/.bashrc
source ~/.bashrc

就彻底完成了，检测时候

roslaunch realsense2_camera rs_camera.launch

就会出现很多的话题，像这样

就是安装成功了，如果没有的话应该是librealsense和realsense_ros的版本不匹配，删掉之前的然后按照教程就OK
