Is ground-truth required during training? #162

Closed lpy523 closed 3 weeks ago

I noticed that the loss function is mentioned in the paper in both the Online Pose Graph Optimization and Neural Object Field sections, and my question is whether ground-truth pose data is needed to supervise the model throughout its training?

I'm sorry I don't understand the paper well enough, if someone could answer my question, I would greatly appreciate it!

No it's not needed. It's only a loss for optimization, w/o comparing to GT.

Where specifically in the code is the loss function in the Online Pose Graph Optimization section defined and called? Thanks! @wenbowen123
