solution
this cartographer turtlebot的编译、安装和运行
I find out in turtlebot 's ~/.bashrc ,I didn’t add
source ~/catkin_ws/install_isolated/setup.bash
into it.

---

after I add source ~/catkin_ws/install_isolated/setup.bash
and catkin_make_isolated --install --use-ninja
result only is:

初步解决方法:https://blog.csdn.net/qq_31159375/article/details/90073967
深入理解:
###此类问题可以归结于:在非图形终端执行了一个GUI程序，导致X11Server在此终端的环境下无法显示图形，需要手动指定X11Server把图形显示到其他的带图形界面的终端。

效果小结
在这之后我直接放弃两台电脑 直接用我的电脑放在最上层 lidar放在第二层
效果可以明显看出 会流畅很多，但是最后的地图还是不太正常。
总体来说，好是感觉会好一些。(对比cartoSLAM)
