Hi @B-Betty, Are you able to compile and run the project. May I know how you did it? Thank you. Right now I am running to "OpenCV was not initialized correctly. Application will be shutdown issue". I have correct version of OpenCV manager (2.4.9) installed. But I am not be able to run the app.

sorry , this repo is too old and has not been maintained since last year. To save trajectory, you may just fill in SaveKeyFrameTrajectoryTUM function in system.cc. To do that , you need to get camera pose and save its translation vector. @B-Betty @BrianTan34
