[TRLC-DK1] LeRobot camera calibration and reprojection error for builders labs (intermediate)

How do you decide whether DK1 camera calibration is truly good enough for LeRobot data collection instead of merely completing without an error?

DK1 teams using LeRobot frequently reach a point where calibration technically completes, but the reprojection error or multi-view alignment still feels suspicious for serious data work.

How are you validating camera calibration quality in DK1 and LeRobot workflows before collecting important episodes?

Please share what reprojection error means in your setup, how you test real-world alignment after calibration, and when you decide calibration must be rerun.

If you reply, include one exact calibration symptom and one exact validation step or threshold that helped.

Comment 1

Great replies will explain how numerical error connects to actual task quality rather than treating one metric as universal truth.

Comment 2

If you use a real-world alignment benchmark after calibration, share it. Those checks are what teams actually search for.

Comment 3

It is also useful to say when recalibration is required versus when a small error is acceptable for the current task.
