vscode字体大小：设置
vscode侧边栏字体大小：ctrl+=,ctrl+-

定位包/文件
sudo apt install mlocate

定位头文件命令
locate Core |grep eigen
Core库，eigen是其下的头文件

vscode添加编译库
ctrl + shift + p
c++ Edit..

在工作路径下一行加上库的路径，注意双引号和逗号。
/**是所有头文件都包含进去（但可能会影响运行速度）

eigen库的使用
Block operations
Dense matrix and array manipulation

#配置eigen，参考这个，不然后续第四章会版本出错
https://blog.csdn.net/weixin_44684139/article/details/104803225?app_version=5.14.2&code=app_1562916241&csdn_share_tail=%7B%22type%22%3A%22blog%22%2C%22rType%22%3A%22article%22%2C%22rId%22%3A%22104803225%22%2C%22source%22%3A%22mengshenglo%22%7D&uLinkId=usr1mkqgl919blen&utm_source=app

如果你有以前的eigen版本，则先卸载
（1）如何判断有老版本

sudo updatedb  
locate eigen3  

（2）进行卸载
sudo rm -rf /usr/include/eigen3 /usr/lib/cmake/eigen3 /usr/share/doc/libeigen3-dev /usr/share/pkgconfig/eigen3.pc /var/lib/dpkg/info/libeigen3-dev.list /var/lib/dpkg/info/libeigen3-dev.md5sums  

安装eigen3.3以上版本（这里我选用最新的3.3.7，注意3.2系列的不可以！！！）
正确方法：
（1）在官网（http://eigen.tuxfamily.org/index.php?title=Main_Page）下载安装包：eigen-3.3.7.tar.bz2 ，然后提取到此处
（2）进入文件夹eigen-3.3.7，右键在终端打开。
（3）进行安装

mkdir build

cd build

cmake ..

sudo make install

注意，新版的eigen路径是/usr/local/include/eigen3，跟以前的不一样。
所以要修改cmakelist.txt
include_directories("/usr/local/include/eigen3")

#配置Pangolin 
sudo apt-get install libglew-dev  
sudo apt-get install cmake  
sudo apt-get install libboost-dev libboost-thread-dev libboost-filesystem-dev

#在slam实例包里
sudo apt install git
git clone https://github.com/stevenlovegrove/Pangolin.git
 
cd Pangolin  
mkdir build  
cd build  
cmake .. 
make

sudo make install

sudo ldconfig

不存在用户定义的从 "pangolin::OpenGlMatrix" 到 "Eigen::Matrix" 的适当转换C/C++(312)

上面报错还是无法解决，但是修改CMakeList.txt中c++版本就行，这是因为下载的pangolin的版本比较高，可以考虑用高翔的，如果用github最新的就修改下面就可以make,但是报错不会消失

set(CMAKE_CXX_FLAGS "-std=c++17")

example例子

plotTrajectory.cpp(文件路径问题，代码爆红问题)
string trajectory_file = "./examples/trajectory.txt";

修改为
string trajectory_file = "../trajectory.txt";

并添加头文件
#include

上面是前三章的

#配置sophus
现如今sophus需要依赖fmt库，因此优先安装fmt：

git clone  https://github.com/fmtlib/fmt.git
cd fmt
mkdir build
cd build
cmake ..
make
sudo make install

主目录下
git clone https://github.com/strasdat/Sophus.git
cd Sophus/

（注，下面的make不要多线程，cmake中有顺序逻辑，并行会出错）
mkdir build
cd build
cmake ..
make
sudo make install

不要回滚git checkout a621ff!!!否则会装成老版本的非模板sophus

ch4
CMakeList.txt ( 同时加入eigen和sophus的依赖 )

cmake_minimum_required(VERSION 3.0)
project(useSophus)

# 为使用 sophus，需要使用find_package命令找到它
find_package(Sophus REQUIRED)
include_directories(${Sophus_INCLUDE_DIRS})

# Eigen
include_directories("/usr/local/include/eigen3")
add_executable(useSophus useSophus.cpp)
target_link_libraries(useSophus ${Sophus_LIBRARIES} fmt)

add_subdirectory(example)

c++ json 自动配置
"/usr/local/include/eigen3"

example中的cpp文件修改为以下路径
string groundtruth_file = "../../example/groundtruth.txt";
string estimated_file = "../../example/estimated.txt";

example下的cmakelist.txt的off改为ON
option(USE_UBUNTU_20 "Set to ON if you are using Ubuntu 20.04" ON)

mkdir build 
cd build/
cmake ..
make

cd example/

./trajectoryError

                "/usr/local/include/opencv4"

#cmakelist.txt文件 3  修改为  4

find_package( OpenCV 4 REQUIRED )

#下面ch5 joinMap 点云库的实例修改
#pcl安装，建议不用
sudo add-apt-repository ppa:v-launchpad-jochen-sprickerhof-de/pcl
#上面命令会报错,然后后续的更新会受到影响，在软件与更新中的其他软件，删除对应的ppa即可正常更新

#执行这两个即可
sudo apt install libpcl-dev
sudo apt update

#版本原因下面包找不到
sudo apt install libpcl-all

#这个工具可以下
sudo apt install pcl-tools

rgbd下的CMakelist.txt修改为
find_package(Sophus REQUIRED)
include_directories(${Sophus_INCLUDE_DIRS})
find_package(Pangolin REQUIRED)

add_executable(joinMap joinMap.cpp)
target_link_libraries(joinMap ${OpenCV_LIBS} ${Pangolin_LIBRARIES} fmt)

undistortImage.cpp
string image_file = "./distorted.png";   // 请确保路径正确
修改为

string image_file = "../../imageBasics/distorted.png";   // 请确保路径正确

joinMap.cpp的路径改为
        ifstream fin("../../rgbd/pose.txt");

        boost::format fmt("../../rgbd/%s/%d.%s"); //图像文件格式

stereoVision.cpp的路径改为
string left_file = "../../stereo/left.png";
string right_file = "../../stereo/right.png";

修改后，
mkdir build 
cd build/
cmake ..
make

cd imageBasics/
./imageBasics ../../imageBasics/ubuntu.png
./undistortImage

cd ..
cd rgbd/
./joinMap

cd ..
cd stereo/
