Ubuntu18.04 —— 新系统从头安装ORB-SLAM3过程（2022年）

一、下载ORB-SLAM3

#具体安装那一版，得具体问题具体分析，我前两版都没成功
#git clone https://github.com/UZ-SLAMLab/ORB_SLAM3.git
#git clone https://github.com/UZ-SLAMLab/ORB_SLAM3/tree/v1.0-release.git
git clone https://github.com/UZ-SLAMLab/ORB_SLAM3/tree/v0.4-beta.git

注意（重要）

在用master和v1.0-release进行安装时，到最后没有运行界面的动画，只生成了CameraTrajectory.txt KeyFrameTrajectory.txt文件，可能是有什么bug，所以推荐安装v0.4-beta，这一版最终成功了！！！
现在是2022年1月2日写，说不定随时间过去作者会进行修复，具体问题具体分析！！！
（可怜我以为是我的问题，安装了好几次都不成功，白白浪费了好几天时间，大哭！！！）

二、安装支持C++11特性的编译器

sudo apt-get install gcc
sudo apt-get install g++
sudo apt-get install build-essential
sudo apt-get install cmake
sudo apt-get install git

三、Pangolin

sudo apt install libgl1-mesa-dev
sudo apt install libglew-dev
sudo apt install libpython2.7-dev
sudo apt install pkg-config
sudo apt install libegl1-mesa-dev libwayland-dev libxkbcommon-dev wayland-protocols

git clone https://github.com/stevenlovegrove/Pangolin/tree/v0.5.git # v-0.5
cd Pangolin
mkdir build
cd build
cmake ..         #有的地方写 cmake -DCPP11_NO_BOOSR=1 .. 也可以，#待验证区别
cmake --build .  #有的地方写 make 也是一样的
sudo make install      (这个也是需要的，网上很多教程没有这个命令)

四、openCV

#查询指定包的详情
apt-cache show libopencv-dev   #version 3.2.0
sudo apt install libopencv-dev --fix-missing
#opencv版本检测
pkg-config --modversion opencv

五、Eigen

apt-cache show libeigen3-dev  #Version: 3.3.4-4
sudo apt install libeigen3-dev --fix-missing

六、boost

sudo apt-get install  libboost-system-dev
或者
sudo apt install libboost-all-dev

sudo apt-get install openssl 
sudo apt-get install libssl-dev

七、ORB-SLAM3

cd ORB_SLAM3
chmod +x build.sh
./build.sh

八、运行结果
