Ubuntu14.04安装Cartographer教程

安装流程

1. 安装Ubuntu14.04（Trusty），将安装镜像文件制作U盘镜像，进入BIOS或WIN10下进入设置->更新和安全->恢复->高级启动，使用U盘启动，完成Ubuntu14.04（Trusty）的安装。
2. 安装ROS（indigo），参考文件http://wiki.ros.org/indigo/Installation/Ubuntu（英文原版）、http://wiki.ros.org/cn/indigo/Installation/Ubuntu（中文翻译）；也有博主自己写的中文版的配置教程，我是照着这个配置的一次成功，链接http://blog.csdn.net/linseeker85/article/details/50658865
   
3. 安装所有依赖项
   

   sudo apt-get install -y google-mock libboost-all-dev  libeigen3-dev libgflags-dev libgoogle-glog-dev liblua5.2-dev libprotobuf-dev  libsuitesparse-dev libwebp-dev ninja-build protobuf-compiler python-sphinx  ros-indigo-tf2-eigen libatlas-base-dev libsuitesparse-dev liblapack-dev  

4. 安装ceres solver，下载安装在主目录下，由于googlesource.com需要FQ，这里使用hitcm（张明明）的github地址
   # Build and install Ceres.
# git clone https://ceres-solver.googlesource.com/ceres-solver
# cd ceres-solver
git clone https://github.com/hitcm/ceres-solver-1.11.0.git
cd ceres-solver-1.11.0
mkdir build
cd build
cmake .. -G Ninja
ninja
ninja test
sudo ninja install
5. 安装cartographer，下载安装在主目录下，这里同样使用的是hitcm（张明明）的github地址
   # Build and install Cartographer.
git clone https://github.com/hitcm/cartographer.git
cd cartographer
mkdir build
cd build
cmake .. -G Ninja
ninja
ninja test
sudo ninja install
6. 安装cartographer_ros，这里使用的是hitcm（张明明）的github地址，由于google官方的教程需要FQ下载一些文件，因此容易失败，经验证hitcm（张明明）对原文件进行了少许修改后可以成功安装，在他的修改中核心代码不变，只修改了编译文件。
   We recommend using wstool and rosdep. For faster builds, we also recommend using Ninja.
   # Install wstool and rosdep.
sudo apt-get update
sudo apt-get install -y python-wstool python-rosdep ninja-build
# Create a new workspace in 'catkin_ws'.
mkdir catkin_ws
cd catkin_ws
wstool init src
# 下载到catkin_ws下面的src文件夹下面
cd src
git clone https://github.com/hitcm/cartographer_ros.git
# 然后到catkin_ws下面运行catkin_make安装
cd
cd catkin_ws
catkin_make，可能会报以下错误：Fatal error: pcl/conversions.h: No such file or directory.，执行sudo apt-get install ros-indigo-pcl-conversions，再次catkin_make即可
7. source ./devel/setup.bash
   注意： 如果每次打开一个新的终端时ROS环境变量都能够自动配置好（即添加到bash会话中），那将会方便得多：
   echo "source ~/catkin_ws/devel/setup.bash" >> ~/.bashrc
source ~/.bashrc
   如果你只想改变当前终端下的环境变量，你可以执行命令：
   source ~/catkin_ws/devel/setup.bash
8. 运行DEMO
   Now that Cartographer and Cartographer’s ROS integration are installed, download the example bags (e.g. 2D and 3D backpack collections of the Deutsches Museum) to a known location, in this case ~/Downloads, and use roslaunch to bring up the demo:
   # Download the 2D backpack example bag.
wget -P ~/Downloads https://storage.googleapis.com/cartographer-public-data/bags/backpack_2d/cartographer_paper_deutsches_museum.bag
# Launch the 2D backpack demo.
roslaunch cartographer_ros demo_backpack_2d.launch bag_filename:=${HOME}/Downloads/cartographer_paper_deutsches_museum.bag
# Download the 3D backpack example bag.
wget -P ~/Downloads https://storage.googleapis.com/cartographer-public-data/bags/backpack_3d/cartographer_3d_deutsches_museum.bag
# Launch the 3D backpack demo.
roslaunch cartographer_ros demo_backpack_3d.launch bag_filename:=${HOME}/Downloads/cartographer_3d_deutsches_museum.bag
# Download the Revo LDS example bag.
wget -P ~/Downloads https://storage.googleapis.com/cartographer-public-data/bags/revo_lds/cartographer_paper_revo_lds.bag
# Launch the Revo LDS demo.
roslaunch cartographer_ros demo_revo_lds.launch bag_filename:=${HOME}/Downloads/cartographer_paper_revo_lds.bag
# Download the PR2 example bag.
wget -P ~/Downloads https://storage.googleapis.com/cartographer-public-data/bags/pr2/2011-09-15-08-32-46.bag
# Launch the PR2 demo.
roslaunch cartographer_ros demo_pr2.launch bag_filename:=${HOME}/Downloads/2011-09-15-08-32-46.bag
   The launch files will bring up roscore and rviz automatically.
