How to make our own Dataset?

[JenkinnLiu]

Hello , I am very grateful your excellent work.
Do you have time to teach us how to make our own dataset like Co-SLAM? I have tried but found the difficulty is how to add the three files (i.e. orbslam2_c2w.json, orbslam2_final.txt and orbslam2_pg.json) containing the run results of ORB-SLAM2 to my own dataset. How can I export these three files? Is there anything to note about the file format? What should be used for parameter configuration (e.g. camera parameters)?
Looking forward to your reply.
