Realsense hand-eye calibration - best practise?

Hello,

what is a good way to do eye-to-hand calibration with a RealSense D435 between the fixed camera and a robot arm (e.g. UR)? I have used the easy_handeye package to calibrate the RGB camera to the robot base, but the result is consistently off by a few cm.

Is it better to calibrate against the IR camera? Is the factory intrinsic calibration of the RealSense typically sufficient?

Best Regards!

You can use the package visp_hand2eye_calibration to do the calibration. The aruca tag is commonly used as the calibration object. It gives accurate calibration.

Factory calibration is usually sufficient.

You can try this repo, which works on ROS2 dashing with realsense D435 and UR5.
