运行ORB-SLAM2
运行教程参考ORB_SLAM2_detailed_comments，但是遇到报错，在文章中有说明，可参照这篇博客操作：ORB_SLAM2–源码编译。
运行ORB_Line_SLAM 资料较少，测试发现其编译步骤与ORB_SLAM2相同，但是编译过程中遇到报错1：

/home/xiujie/Downloads/ORB_Line_SLAM-master/src/Tracking.cc:2382:13: error: ‘usleep’ was not declared in this scope2382 | usleep(3000);
针对报错1不要按照它的提示修改文件，参照博客编译stvo-pl报错error: ‘random_device’ was not declared in this scope 解决方案，我选用在报错的.h文件内添加万能头文件，只在报错文件添加即可。
#include<bits/stdc++.h>
针对报错2，参考博客编译orbslam2出现的error: ‘usleep’ was not declared in this scope usleep(3000)，只需要在报错的相关.h文件内添加
#include<unistd.h>
两个SLAM代码至此编译成功！
