All Supported Calibrators

SUMMARY

Axon has three calibrators, one per calibration problem: a single camera's intrinsics, a wrist-mounted camera's transform to the robot TCP, and the extrinsics between synchronized cameras. Pick the one matching your setup and follow its link below.

Calibrator

MultiCameraCalibrator

Solves extrinsics between N synchronized cameras, with triangulation validation.

Calibrator	Solves
IntrinsicCalibrator	Camera intrinsic matrix and distortion coefficients
EyeInHandCalibrator	tcp_T_camera, wrist camera to robot TCP
MultiCameraCalibrator	Extrinsics between N >= 2 synchronized cameras

Choosing a Calibrator

• Need a camera's intrinsic matrix and distortion coefficients? Use IntrinsicCalibrator.
• Camera rigidly mounted on a robot's wrist? Use EyeInHandCalibrator to solve tcp_T_camera.
• Two or more synchronized, static cameras? Use MultiCameraCalibrator to solve each camera's pose relative to a reference camera.

All three share the same primary skill, calibrate(), see Calibrate for the cross-calibrator signature and return-type comparison.
