ORB_SLAM需要修改的部分包括CMakelist.txt和rgbd_tum.cc，这部分需要较大改动。首先看rgbd_tum.cc，由于我们打算完成一个实时系统，所以不在需要数据的读取、color和depth的匹配；可以省去相当部分的工作。最后展示所有的rgbd_tum.cc代码

1. 地图点相关 3. 用参考关键帧来跟踪 1. 理解地图点里成员变量的物理意义 2. 掌握BOW的原理及应用（重要） 3. 掌握关键帧跟踪原理（重要） 4.

ORB-SLAM2 is a real-time SLAM library for **Monocular**, **Stereo** and **RGB-D** cameras that computes the camera trajectory and a sparse 3D reconstruction (in the stereo and RGB-D case with true scale). It is able to detect loops and relocalize the camera in real time. We provide examples to run the SLAM system in the [KITTI dataset](http://www.cvlibs.net/datasets/kitti/eval_odometry.php) as stereo or monocular, in the [TUM dataset](http://vision.in.tum.de/data/datasets/rgbd-dataset) as RGB-D

此为ORB_SLAM2位姿发布所需的文件，里面包括头文件以及cpp文件；

此资源包里包括ORB_SLAM2算法源码以及发布位姿信息所需要的文件，以及对应的文件正确的放置位置。仅供参考。
