# Custom Calibration

Prerequisite: You must compute the positions on the motion system before you run the custom calibration commands.

Use these commands to determine the position of the camera in the coordinate space of the motion system, when not all motions for the motion system can be performed within the field of view of the camera.

Custom calibration is a three-step process:

1. Initialize the calibration (CCB)
2. Provide the positions from the motion system (CC)
3. Compute the calibration (CCE)
