Camera Calibration Tool

The Camera Calibration Tool helps align the virtual camera with the camera in your virtual
production studio.

The Camera Calibration Tool determines the parameters of the physical camera (for example,
position offset, lens distortion data, and field of view), which you can use to configure the virtual
camera in your virtual production software.

Use your camera and the Camera Calibration Tool to capture images of the chessboard pattern
on the calibration board at three different angles. The Camera Calibration Tool will then use the
data obtained from the images to align the virtual camera with your on-set camera. For details,
see 

Calibrating your camera

 on page 22.

Calibrating your camera
