文章介绍了如何使用Cartographer进行SLAM建图，包括通过ROS环境安装Cartographer，解决访问限制和依赖问题，以及针对A1雷达和香橙派平台的配置细节，如lua文件修改和串口重映射。

cartographer是一个性能优越的slam建图方案，记录下学习过程

官网：

cartographer官网

首先需要一个ros环境

wget http://fishros.com/install -O fishros && . fishros

推荐小鱼的一键安装！能避免很多弯路

然后cartographer的安装过程推荐以下博客

博客

然后有几个注意点：

1.在网址前加一下https://ghproxy.com/ 进行代理，不然访问不了

2.按照指示安装缺少的依赖即可；如果报错缺少libabsl-dev，这个是安不了的，要删掉

3.还可能是某些库版本不对，要重新安装，这个看报错这么说。

安装之后demo跑通之后就可以玩自己的了。

我是思岚A1雷达加香橙派建图。单激光雷达。

见博客

这个有个错漏的地方

use_pose_extrapolator = true

TRAJECTORY_BUILDER.collate_landmarks = true

在lua文件加入这两行。

注意source

rplidar这个包见雷达官方给的操作声明，同样，记得source

以及串口重映射的问题
