rosbag ground thruth not aligned with docker results #50

Open geoeo opened 4 years ago

geoeo commented 4 years ago

Hello,

I am plotting the GT pose from the topic /Robot_7/pose with the docker image. However, the aft_mapped/camera and gt_pose transforms are not aligned. Is there some transform step that is not given to align the two?

Gt is bottom left, while aft_mapped and camera are on the right. Its a bit faint.

Hi @geoeo, since these two are not in the same coordinate. An alignment is required to visualize this two together.

Would it be possible to know what this alignment is? It would make comparison between local and global methods possible

did you know VINS-Fusion, the method to fuse VIO and GPS, maybe we can try to fuse LIO and GPS.

I have only seen the repo. Is there a publication for this method?
