Introduction

The Camera Calibration Tool captures images to generate calibration data (focal length, lens distortion, nodal point offset, etc.) that you can import into your virtual production engine to simulate your virtual camera. Camera Calibration Tool v1.2.4.15 (or newer version) supports multiple focal length calibration and focus mapping. This tutorial would walk through the calibration flow.

Preparation

1. Camera Calibration Tool: If you haven't downloaded the Camera Calibration Tool, visit www.vive.com/mars/cct.
2. VIVE Mars CamTrack, two Rovers, Calibration Board, and camera zoom lens.
3. At least one VIVE Mars FIZTrack lens encoder.
4. Windows PC with video capture device. (e.g.: Blackmagic DeckLink 8K Pro, AJA KONA 5,…)

1. Install a VIVE Mars FIZTrack lens encoder to the camera and connect it to Rover. See: Setting up the FIZTrack lens encoder.
2. Reset the FIZTrack lens encoder value to zero. See: Resetting the FIZTrack lens encoder to zero.
