在Ubuntu16.04上安裝ORBSLAM2，參考文檔：http://www.cnblogs.com/wongyi/p/8596084.html

執行代碼：

./Examples/Monocular/mono_tum Vocabulary/ORBvoc.txt Examples/Monocular/TUM1.yaml ../rgbd_dataset_freiburg1_xyz

然後它就正常執行了，但是不明白為什麽中間輸出的信息中含有大量的以下代碼：（我是已經安裝了OpenGL並且按照https://blog.csdn.net/zhangliang_571/article/details/25241911這篇文章介紹的方法測試成功了的。）

我想知道這是為什麽呢？請教大家，先謝謝大家。
