Calibration Board
Calibration board is usually 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: BDB, CGB and OCB.
CGB
For V4 cameras.

Mounting Method
In the following calibration scenarios, you can mount the calibration board on the last joint of the robot.
-
Automatic Calibration in the Eye to Hand (ETH) Scenario
-
Manual Calibration in the ETH Scenario (Multiple Random Calibration Board Poses)
| For other calibration scenarios and intrinsic parameter checks, there is no need to mount the calibration board. Please place the calibration board in the center of the object plane. |
Common ways to mount the calibration board are shown below:
| Direct mounting | Mounting through the flange adapter |
