写在最前
- 本文建议在不能科学上网的同学，最好采用手机热点进行安装
- 如果你的ROS环境是刚刚安装好，不怕乱动的最好了
- rosdep更新：可以采用sudo pip3 install rosdepc
- 文中所有的命令路径都无需切换

【安装学习】安装Cartographer ROS（noetic）
安装cartographer步骤及问题解决
1. 创建工作空间并初始化
-
- 创建工作空间：
mkdir -p ~/catkin_google_ws/src
- 创建工作空间：
-
- 跳转到工作空间：
cd ~/catkin_google_ws/src/
- 跳转到工作空间：
-
- 在2的命令下，初始化工作空间
catkin_init_workspace
- 在2的命令下，初始化工作空间
pc@pc:~$ mkdir -p ~/catkin_google_ws/src
pc@pc:~$ ls
catkin_google_ws Documents Music Public Videos
Desktop Downloads Pictures Templates
pc@pc:~$ cd ~/catkin_google_ws/src/
pc@pc:~/catkin_google_ws/src$ catkin_init_workspace
Creating symlink "/home/pc/catkin_google_ws/src/CMakeLists.txt" pointing to "/opt/ros/noetic/share/catkin/cmake/toplevel.cmake"
2. 安装下载工具并下载谷歌Cartographer
-
- 更新一下软件源：
sudo apt-get update
- 更新一下软件源：
-
- 安装下载工具：
sudo apt install -y python3-wstool ninja-build stow
- 安装下载工具：
-
- 切换到工作空间：
cd ~/catkin_google_ws/
- 切换到工作空间：
-
- wstool工具初始化工作空间：
wstool init src
- wstool工具初始化工作空间：
pc@pc:~/catkin_google_ws$ sudo apt install -y python3-wstool ninja-build stow

-
- 工作空间下merge远程的代码库：
wstool merge -t src https://raw.githubusercontent.com/cartographer-project/cartographer_ros/master/cartographer_ros.rosinstall，merge代码出错查看第4.1节内容
- 工作空间下merge远程的代码库：
-
- wstool工具更新源文件：
wstool update -t src，由于github的不稳定性，这一步多半失败，更新出错见4.2解决方法
- wstool工具更新源文件：
-
- 安装abseil cpp库：切换到工作空间目录：
cd ~/catkin_google_ws/，输入命令src/cartographer/scripts/install_abseil.sh，安装库
- 安装abseil cpp库：切换到工作空间目录：
-
- 安装依赖项：
rosdep install --from-paths ~/catkin_google_ws/src --ignore-src -r，该命令主要替代rosdep install --from-paths src --ignore-src --rosdistro=noetic -y,但是后续可能弄乱环境，需要重新安装ROS，即sudo apt install ros-noetic-desktop-full
- 安装依赖项：
pc@pc:~/catkin_google_ws$ rosdep install --from-paths src --ignore-src --rosdistro=noetic -y
ERROR: the following packages/stacks could not have their rosdep keys resolved
to system dependencies:
cartographer: [libabsl-dev] defined as "not available" for OS version [focal]
-
- 编译Cartographer：
catkin_make_isolated --install --use-ninja，这一个最关键，不报错，说明catrograppher部署成功了，那么恭喜你，可以开始Cartographer的学习了！
- 编译Cartographer：
pc@pc:~/catkin_google_ws$ catkin_make_isolated --install --use-ninja
... ....

3. 测试Cartographer
3.1 下载官方的二维模型
-
- 下载模型可以用wget方式或者直接http下载，下载的位置就在工作空间下：
wget -P ~/catkin_google_ws/ https://storage.googleapis.com/cartographer-public-data/bags/backpack_2d/cartographer_paper_deutsches_museum.bag
- 下载模型可以用wget方式或者直接http下载，下载的位置就在工作空间下：
3.2 测试运行Cartographer
-
- 激活环境，激活环境前确保你的catrographer项目是编译通过的，即第12步不报错：
source devel_isolated/setup.bash
- 激活环境，激活环境前确保你的catrographer项目是编译通过的，即第12步不报错：
-
- 启动官方demo：
roslaunch cartographer_ros demo_backpack_2d.launch bag_filename:=${HOME}/catkin_google_ws/cartographer_paper_deutsches_museum.bag
- 启动官方demo：
pc@pc:~/catkin_google_ws$ source devel_isolated/setup.bash
pc@pc:~/catkin_google_ws$ roslaunch cartographer_ros demo_backpack_2d.launch bag_filename:=${HOME}/catkin_google_ws/cartographer_paper_deutsches_museum.bag
4. 错误解决办法，和附件
4.1 merge代码出错解决
- 在第8步中，merge代码多半出现
pc@pc:~/catkin_google_ws$ wstool merge -t src https://raw.githubusercontent.com/cartographer-project/cartographer_ros/master/cartographer_ros.rosinstall
ERROR in config: Unable to download URL [https://raw.githubusercontent.com/cartographer-project/cartographer_ros/master/cartographer_ros.rosinstall]:
- 此时复制
https://raw.githubusercontent.com/cartographer-project/cartographer_ros/master/cartographer_ros.rosinstall连接也发现进不去，多半肯定是不成功
- 方法一：换手机热点多试几次，能成功
- 方法二：直接跑到src的目录下，添加需要merge的信息：
- 8.1 进入src目录：
cd ~/catkin_google_ws/src/，输入ls -a可以查看是否有.rosinstall文件 - 8.2 编辑
.rosinstall文件：sudo gedit ~/catkin_google_ws/src/.rosinstall，保存关闭，进入第九步：
# THIS IS AN AUTOGENERATED FILE, LAST GENERATED USING wstool ON 2022-10-27
- git: {local-name: cartographer, uri: 'https://github.com/cartographer-project/cartographer.git', version: 'master'}
- git: {local-name: cartographer_ros, uri: 'https://github.com/cartographer-project/cartographer_ros.git', version: 'master'}
4.2 wstool update -t src报错解决办法
- 报错内容：
pc@pc:~/catkin_google_ws$ wstool update -t src

解决方法：
-
- 切换热点多试几次
-
- 直接进入GitHub下载文件夹：https://github.com/cartographer-project，可以看到几个文件，将两个C++文件进入到下载页面下载下来https://github.com/cartographer-project/cartographer，https://github.com/cartographer-project/cartographer_ros
- 直接进入GitHub下载文件夹：https://github.com/cartographer-project，可以看到几个文件，将两个C++文件进入到下载页面下载下来https://github.com/cartographer-project/cartographer，https://github.com/cartographer-project/cartographer_ros
-
- 将两个文件解压到
catkin_google_ws/src下，看到文件夹后面有尾缀master，删除-master：
