How to get pose or path in Pangolin viewer

[taehoon11]

I try to get pose or path(pose_graph) in Viewer.

Because I want to compare ORB_pose with Vins_mono pose. but idon't know How to get data

I try to "rosbag record", it just contain Image and IMU data

I Think This ORB_SLAM3 Package is not for ROS...
