Calibration is a process of computing accurate camera positions and orientations from a video. This step is essential and required for multi-camera system setup. 

Calibration can be done by user waving a small glowing object called ''marker'' (for color/color+depth cameras). Novel AI-based pose estimation algorithms allow to use AI-detected joint positions instead of glowing object (flashlight), that makes the process simpler.

{{Important|Once you calibrated the camera system, you should not move your cameras for subsequent video shoots. If you move at least one camera, you need to perform calibration again.}}

{{Tip|We recommend to run calibration twice - before and after capture session. If any camera was moved during capture session, calibration made after the session can give you correct camera positions.}}
