一、首先安装ROS环境
1.确保系统软件处于最新版：
$ sudo apt-get update2.打开终端，输入命令
wget https://raw.githubusercontent.com/oroca/oroca-ros-pkg/master/ros_install.sh && \
chmod 755 ./ros_install.sh && bash ./ros_install.sh catkin_ws kinetic直到完成，安装过程中可能出现网络问题导致某些包安装失败，请多次运行上述命令以确保安装完全。
3.初始化ROS
$ sudo rosdep init
$ rosdep update
4.初始化环境变量：
$ echo "source /opt/ros/kinetic/setup.bash" >> ~/.bashrc
$ source ~/.bashrc
5.安装常用插件：
$ sudo apt-get install python-rosinstall
6.测试ROS，启动ROS环境：
（1）、CTRL+ALT+T打开终端（Termial），输入以下命令，初始化ROS环境：
$ roscore
（2）、成功打开如下图所示：
上面显示有ROS的版本，还有一些节点、端号等内容。
(3)、再 打开一个新的终端（Termial），输入以下命令，弹出一个小乌龟窗口：
rosrun turtlesim turtlesim_node
(4)、出现一个小乌龟的LOGO后，再 打开一个新的终端（Termial），输入以下命令
rosrun turtlesim turtle_teleop_key
然后，通过方向键控制小乌龟的移动：如下图所示
（5）、 打开新的Termial，输入以下命令，可以查看ROS节点信息：
rosrun rqt_graph rqt_graph
如果你能顺利进行到这一步，说明ROS安装成功了。
二、由于ROS自带OPENCV，不需要安装OPENCV，如果需要安装请按如下步骤安装
[compiler] sudo apt-get install build-essential
[required] sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
[optional] sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev
$ git clone https://github.com/opencv/opencv.git
$ cd opencv/
$ git checkout tags/3.4.1
$ mkdir _build
$ cd _build/
$ cmake \
-DCMAKE_BUILD_TYPE=RELEASE \
-DCMAKE_INSTALL_PREFIX=/usr/local \
\
-DWITH_CUDA=OFF \
\
-DBUILD_DOCS=OFF \
-DBUILD_EXAMPLES=OFF \
-DBUILD_TESTS=OFF \
-DBUILD_PERF_TESTS=OFF \
..
$ make -j4
$ sudo make install三、 Eigen安装
1.未安装Eigen的PC可以输入以下命令进行安装：
sudo apt-get install libeigen3-dev
四、Cere的安装
1.可去GitHub上下载Ceres：Ceres下载地址
最新版本可从git库克隆：
以下安装步骤参照《SLAM十四讲》进行
安装依赖项：(若为Ubuntu14.04则应为libcxsparse3.1.2）
sudo apt-get install liblapack-dev libsuitesparse-dev libcxsparse3.1.4 libgflags-dev libgoogle-glog-dev libgtest-dev
2.以下安装参照安装教程进行
安装依赖项：
#CMake
sudo apt-get install cmake
＃google-glog + gflags
sudo apt-get install libgoogle-glog-dev
#BLAS＆LAPACK
sudo apt-get install libatlas-base-dev
#Eigen3
sudo apt-get install libeigen3-dev
#SuiteSparse和CXSparse（可选）
＃ - 如果要将Ceres构建为* static *库（默认），您可以在主Ubuntu软件包#storage中使用SuiteSparse软件包：
sudo apt-get install libsuitesparse-dev
＃ - 但是，如果要将Ceres构建为* shared *库，则必须添加以下PPA：
sudo add-apt-repository ppa：bzindovic / suitesparse-bugfix-1319687
sudo apt-get update
sudo apt-get install libsuitesparse-dev
3.解压Cere安装包，进入安装目录下：
tar zxf ceres-solver-1.14.0.tar.gz
cd ceres-solver-1.14.0
mkdir build
cmake ..
make
make install
五、在ROS上构建VINS-Mono
1.ROS安装额外的ROS pacakge：
sudo apt-get install ros-kinetic-cv-bridge ros-kinetic-tf ros-kinetic-message-filters ros-kinetic-image-transport
2.在ROS上构建VINS-Mono，克隆存储库和catkin_make：
cd ~/catkin_ws/src
git clone https://github.com/HKUST-Aerial-Robotics/VINS-Mono.git
cd ../
catkin_make
source ~/catkin_ws/devel/setup.bash
六、下载安装MYNTEYE-SDK包
如果是S系列，下载
$:sudo apt-get install git
$:git clone https://github.com/slightech/MYNT-EYE-S-SDK.git
$:cd MYNT-EYE-S-SDK
$:make init
$:make samples
$:make tools
$:make ros
$:source wrappers/ros/devel/setup.bash获取S系列图像标定参数
$:cd <SDK>
$:./samples/_output/bin/tutorials/get_img_params会显示如下参数（每种分辨率下对应不同的图像参数）

把$:./samples/_output/bin/tutorials/get_img_params获取的S系列图像参数进行替换上个文件相应的位置，按照规则如下
D[0, 1, 2, 3, 4] -> [k2, k3, k4, k5, 0]
K[mu, 0, u0, 0, mv, v0, 0, 0, 1]->[mu, mv, u0, v0]
用左目（left）参数替换参数既可
在VINS-Mono\vins_estimator\launch下添加mynteye-s.launch文件内容如下
<launch>
<arg name="config_path" default = "$(find feature_tracker)/../config/mynteye-s/mynteye_config.yaml" />
<arg name="vins_path" default = "$(find feature_tracker)/../config/../" />

distortion_parameters:coeffs:[k1,k2,p1,p2,0]->(k1,k2,p1,p2)在VINS-Mono\vins_estimator\launch下添加mynteye-d.launch文件内容如下
<launch>
<arg name="config_path" default = "$(find feature_tracker)/../config//mynteye-d/mynteye_config.yaml" />
<arg name="vins_path" default = "$(find feature_tracker)/../config/../" />
<node name="feature_tracker" pkg="feature_tracker" type="feature_tracker" output="log">

</launch>
2.重新编译初始化VINS
cd ~/catkin_ws/src
catkin_make
source ~/catkin_ws/devel/setup.bash八、启动VINS
1.在sdk目录下启动摄像头
cd <SDk>
#S系列
roslaunch mynt_eye_ros_wrapper mynteye.launch
#D系列
roslaunch mynteye_wrapper_d mynteye.launch2.在VINSMONO目录下启动vins
cd ~/catkin_ws/
#S系列
roslaunch vins_estimator mynteye-s.launch
#D系列
roslaunch vins_estimator mynteye-d.launch3.运行节点，新窗口同时打开 RViz 预览：
#S系列
source wrappers/ros/devel/setup.bash
roslaunch mynt_eye_ros_wrapper display.launch
#D系列
source ./wrappers/ros/devel/setup.bash
roslaunch mynteye_wrapper_d display.launch启动坐标显示，新开个窗口输入
rostopic echo /vins_estimator/odometry4.录制播放视频包功能(可选)
(1)新建个文件夹bag，在文件夹创建两个文件
创建record_bag文件内容如下
#S系列写这个
rosbag record -O mynt-s.bag /mynteye/imu/data_raw /mynteye/left/image_raw
#注意上面下面二选一
#D系列写下面的
rosbag record -O mynt-d.bag /mynteye/imu/data_raw /mynteye/left/image_color
创建play文件内容如下
#S系列写这个
rosbag play mynt-s.bag
#注意上面下面二选一
#D系列写下面的
rosbag play mynt-d.bag
(2)录制或者播放（播放的时候要关掉sdk运行的ros）
./record_bag开始录制，CTL+C停止录制，./play开始播放
