Re-calibrate Extrinsic Parameters

If a picking inaccuracy issue occurs, you need to re-calibrate the extrinsic parameters after detecting and resolving the following issues:

Hardware issues are detected, such as changing the camera and gripper.
Camera’s intrinsic parameters error becomes larger.
It is detected that extrinsic parameter accuracy deteriorates by using the extrinsic parameter error analysis tool.
The robot absolute accuracy has declined.

Refer to Hand-Eye Calibration Guide to re-calibrate the extrinsic parameters.

If the project uses 3D matching for recognition and the point cloud model is made by teaching, please make the point cloud model again after re-calibrating the extrinsic parameters.
