ORB-SLAM2运行

  • 安装pangolin

pangolin的github地址https://github.com/stevenlovegrove/Pangolin

在安装Pangolin时出现问题

参考https://blog.csdn.net/weixin_38504276/article/details/100673890

解决办法:

sudo apt-get install libxkbcommon-x11-dev

然后再cmake ..

使用ros的参考https://blog.csdn.net/RadiantJeral/article/details/82193370

  • 安装orb-slam2

orb-slam2的github地址https://github.com/raulmur/ORB_SLAM2

安装和跑通参考https://blog.csdn.net/u014709760/article/details/85253525

问题:usleep

参考https://www.cnblogs.com/bigzhao/p/6537562.html

参考github上的回答https://github.com/raulmur/ORB_SLAM2/pull/834/commits/d5be22c12aedde9265d766baa036021883b97cc0

在以下的文件中加入头文件#include <unistd.h>

/home/***/ORB_SLAM2/src/LoopClosing.cc

/home/f**/ORB_SLAM2/src/LocalMapping.cc

/home/***/ORB_SLAM2/src/System.cc

/home/***/ORB_SLAM2/src/Tracking.cc

/home/***/ORB_SLAM2/src/Viewer.cc

/home/***/ORB_SLAM2/Examples/Monocular/mono_euroc.cc

/home/*c*/ORB_SLAM2/Examples/Monocular/mono_kitti.cc

/home/***/ORB_SLAM2/Examples/Monocular/mono_tum.cc

/home/***/ORB_SLAM2/Examples/RGB-D/rgbd_tum.cc

/home/***/ORB_SLAM2/Examples/Stereo/stereo_euroc.cc

/home/**l/ORB_SLAM2/Examples/Stereo/stereo_kitti.cc

正确的src和Example的文件夹在文档里

  •  跑EuRoC的V1_01_easy数据集

参考github地址

输入./Examples/Monocular/mono_euroc Vocabulary/ORBvoc.txt Examples/Monocular/EuRoC.yaml PATH_TO_SEQUENCE_FOLDER/mav0/cam0/data Examples/Monocular/EuRoC_TimeStamps/SEQUENCE.txt 

以medium为例,在ORB-SLAM2文件夹下

./Examples/Monocular/mono_euroc Vocabulary/ORBvoc.txt Examples/Monocular/EuRoC.yaml /home/***/dataset/V1_02_medium/mav0/cam0/data Examples/Monocular/EuRoC_TimeStamps/V102.txt 

注意在该路径下不用在路径下加/,但是如果跳出了该路径要加上/,如/home

出现问题Failed to load module "canberra-gtk-module"

由链接下载https://blog.csdn.net/u014337397/article/details/81068991

sudo apt-get install libcanberra-gtk-module

  • 位姿图

之后,在ORB-SLAM2的文件夹下出现KeyFrameTrajectory.txt文件。

把它移植到另一个文件夹,我的是

/home/***/reconstruction/ORB-SLAM2-V1_01_easy/路径下面

并改名字

然后在

/home/***/dataset/V1_01_easy/mav0/state_groundtruth_estimate0/

路径下运行代码

evo_traj tum /home/***/reconstruction/ORB-SLAM2-V1_01_easy/KeyFrameTrajectory.txt  --ref=ground_truth.tum -p --plot_mode=xyz --align --correct_scale

成功!

另外大家常见的不对齐问题参考http://www.mamicode.com/info-detail-2916431.html

今天用orbslam2跑euroc数据集,将结果和真实轨迹用evo测评,发现差别特别大:

evo_traj tum data.tum CameraTrajectory.txt --plot --plot_mode=xy
最后发现两组数据没有对齐,evo提供了自动对齐与尺度校正功能,正确的用法如下:(需要指定参考数据--ref=data.tum)

evo_traj tum CameraTrajectory.txt --ref=data.tum -p --plot_mode=xy --align --correct_scale

 

其他的研究比如:ORB-SLAM2地图保存加载以及重定位参考https://blog.csdn.net/learning_tortosie/article/details/81384717
