Reprojection error when extrinsics calibration

Autonomous Vehicles DRIVE PX 2 DriveWorks

Hi,

We use driveworks 1.2.400 to do camera calibration and totally followed the tutorial from Nvidia.

However, there’s lots of reprojection error happened when running calibration-graph-cli tool.

So is there any potential reasons to such an error which can give us some suggestion?

Thanks a lot!
