Calibration Board¶
Calibration board is used for intrinsic parameter check and hand-eye calibration. This chapter introduces the types, models, and mounting methods of calibration boards.
Calibration Board Types and Models¶
Mech-Mind provides three types of calibration boards:
OCB¶
OCB calibration boards have no mounting holes and therefore cannot be mounted on the last joint of the robot. It can be used only when the camera is mounted in the EIH mode.

Mount Calibration Board¶
For hand-eye calibration in the ETH mode, the calibration board should be mounted on the last joint of the robot. Common ways to mount the calibration board are shown below:
Direct mounting |
Mounting through the flange adapter |
