Collecting calibration data using the Camera Calibration Tool
The
Camera Calibration Tool captures images to generate calibration data that you can import into your virtual production engine to calibrate your camera.

Attach a
Rover module to your camera, with the front side of
Rover parallel to the camera lens.
Note: The internal screw thread on the bottom of Rover has a depth of 5.5 mm. To avoid damaging Rover or your camera during installation, make sure the exterior screw thread on your camera is no longer than 4.5 mm.
