1. 准备运行环境和依赖

1.1 系统环境

Ubuntu 16.04 LTS，最好是干净的系统。

可以到阿里巴巴开源镜像站或其他下载站下载系统镜像。 https://mirrors.aliyun.com/ubuntu-releases/16.04/ubuntu-16.04.6-desktop-amd64.iso

安装git、cmake、vim、wget

sudo apt-get update
sudo apt-get install git
sudo apt-get install cmake
sudo apt-get install vim
sudo apt-get install wget

1.2 ROS

安装说明：http://wiki.ros.org/cn/kinetic/Installation/Ubuntu

1.2.1 配置 Ubuntu 软件仓库

配置你的 Ubuntu 软件仓库(repositories) 以允许 “restricted”、“universe” 和 “multiverse"这三种安装模式。你可以按照ubuntu中的配置指南来完成配置。

1.2.2 添加 sources.list

官方源速度有些慢，添加中科大源

1
sudo sh -c '. /etc/lsb-release && echo "deb http://mirrors.ustc.edu.cn/ros/ubuntu/ $DISTRIB_CODENAME main" > /etc/apt/sources.list.d/ros-latest.list'

或清华源

1
sudo sh -c '. /etc/lsb-release && echo "deb http://mirrors.tuna.tsinghua.edu.cn/ros/ubuntu/ $DISTRIB_CODENAME main" > /etc/apt/sources.list.d/ros-latest.list'

1.2.3 添加key

1
sudo apt-key adv --keyserver hkp://ha.pool.sks-keyservers.net:80 --recv-key 421C365BD9FF1F717815A3895523BAEEB01FA116

添加公钥（官方文档没有这一步，但是不添加公钥会报不信任错误）

1
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys F42ED6FBAB17C654

1.2.4 安装

1
sudo apt-get update

安装桌面完整版

1
sudo apt-get install ros-kinetic-desktop-full

1.2.5 初始化rosdep

1
2
sudo rosdep init
rosdep update

1.2.6 环境配置

1
2
echo "source /opt/ros/kinetic/setup.bash" >> ~/.bashrc
source ~/.bashrc

1.2.7 构建工厂依赖

1
sudo apt-get install python-rosinstall python-rosinstall-generator python-wstool build-essential

1.2.8 配置ROS环境，创建工作空间

参考：http://wiki.ros.org/cn/ROS/Tutorials/InstallingandConfiguringROSEnvironment

mkdir -p ~/catkin_ws/src
cd ~/catkin_ws
catkin_make
source devel/setup.bash
echo "source ~/catkin_ws/devel/setup.bash" >> ~/.bashrc
source ~/.bashrc

1.3 小觅相机SDK

本部分参考官方文档SDK安装部分，安装到目录~/MYNT/SDK下（路径根据需要可自行修改）
https://mynt-eye-s-sdk.readthedocs.io/zh_CN/latest/src/sdk/install_ubuntu_src.html

cd <sdk>
source wrappers/ros/devel/setup.bash
roslaunch mynt_eye_ros_wrapper mynteye.launch     #开摄像头，但默认不显示图像
roslaunch mynt_eye_ros_wrapper display.launch    #也可以运行这个节点，会打开 RViz 显示图像

获取参数

cd <sdk>
./samples/_output/bin/tutorials/get_img_params     #获取相机标定参数
./samples/_output/bin/tutorials/get_imu_params     #获取IMU标定参数

1.4 依赖项

1.4.1 安装Pangolin

准备依赖

sudo vim /etc/ld.so.conf.d/opencv.conf

在其中添加

1
/usr/local/lib

使之生效

1
sudo ldconfig

在bash.bashrc中添加路径

1
sudo vim /etc/bash.bashrc

在其中添加

1
PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig export PKG_CONFIG_PATH

使之生效

2. 编译安装

下载源码

3
cd ~/catkin_ws/src
git clone https://github.com/slightech/MYNT-EYE-ORB-SLAM2-Sample.git MYNT-ORB
#下载到~/catkin_ws/src/MYNT-ORB文件夹

配置路径
1 2 3 4
# 打开~/.bashrc sudo vim ~/.bashrc # 在最后添加： export ROS_PACKAGE_PATH=${ROS_PACKAGE_PATH}:~/catkin_ws/src/MYNT-ORB/Examples/ROS
如果添加之后编译ros的时候还是报错，如果有多个 ROS_PACKAGE_PATH 尝试更改一下位置，我将其从最后一个提到前面就不报错了（神奇=_=）。
