cartographer 是一个 Google 开源的用于实时构建二维和三维地图的 SLAM(Simultaneous Localization and Mapping)系统,而 protobuf 是 Google 开源的一种数据序列化协议。它们之间没有直接的关系,但是在 cartographer 中使用了 protobuf 来序列化和反序列化数据。

cartographer安装_cartographer安装
安装Cartographer有一些先决条件需要满足,包括CMake、Google Protocol Buffers和Google的catkin工具。以下是在Ubuntu Linux上安装Cartographer的步骤:
1. 安装依赖项:
```
sudo apt-get update
sudo apt-get install -y \
cmake \
g++ \
git \
google-mock \
libboost-all-dev \
libcairo2-dev \
libeigen3-dev \
libgflags-dev \
libgoogle-glog-dev \
liblua5.2-dev \
libprotobuf-dev \
libsuitesparse-dev \
lsb-release \
ninja-build \
protobuf-compiler \
python-sphinx
```
2. 安装Google的catkin工具:
```
sudo apt-get install -y python-rosdep python-catkin-tools
```
3. 创建一个工作空间并初始化catkin:
```
mkdir -p ~/catkin_ws/src
cd ~/catkin_ws/
catkin init
```
4. 克隆Cartographer代码库并检查最新版本:
```
cd src/
git clone https://github.com/cartographer-project/cartographer.git
cd cartographer/
git checkout master
```
5. 安装依赖项和编译:
```
# 安装依赖项
rosdep update
rosdep install --from-paths src --ignore-src --rosdistro=${ROS_DISTRO} -y
# 编译
catkin build cartographer_ros -DCATKIN_ENABLE_TESTING=OFF
```
6. 配置环境变量:
```
source ~/catkin_ws/devel/setup.bash
```
现在,您已经成功地安装了Cartographer。
cartographer导航
要在ROS中使用Cartographer导航,首先需要安装Cartographer和Cartographer ROS。Cartographer是用来执行SLAM(Simultaneous Localization and Mapping)任务的算法库,而Cartographer ROS是一个ROS功能包,用于调用Cartographer算法。
首先,确保已经安装了Ceres Solver和Protobuf。这两个库是Cartographer的依赖项。
然后,使用以下命令安装Cartographer和Cartographer ROS:
```
sudo apt-get install ros-$ROS_DISTRO-cartographer
sudo apt-get install ros-$ROS_DISTRO-cartographer-ros
```
安装完成后,可以在ROS中使用Cartographer导航。首先,需要启动Cartographer SLAM节点,使用以下命令:
```
roslaunch cartographer_ros cartographer.launch
```
这将启动Cartographer SLAM节点,开始执行SLAM任务,并发布地图。
接下来,可以启动Cartographer Occupancy Grid节点,使用以下命令:
```
roslaunch cartographer_ros cartographer_occupancy_grid.launch
```
这将订阅来自Cartographer SLAM节点的地图信息,并将其发布为占据栅格地图。
现在,你可以使用导航功能包(如move_base)来进行导航。设置导航目标,并使用相应的导航命令,机器人将会根据Cartographer生成的地图进行导航。
总结来说,要在ROS中使用Cartographer导航,首先要安装Cartographer和Cartographer ROS,然后启动Cartographer SLAM节点和Cartographer Occupancy Grid节点,最后使用导航功能包进行导航。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
