1. Click the Play button to start the calibration process.

  2. Follow the instruction to move the camera, so the calibration pattern falls inside the red frame.

This depends on the different camera configurations.

  1. Move the camera as needed to capture additional images until you're prompted to rotate the calibration board.

  2. Rotate the calibration board 45 degrees (counterclockwise), then click Continue and capture a second set of images. After capturing the second set of images, you'll be prompted to rotate the board 45 degrees in the opposite direction.

  3. Rotate the calibration board 45 degrees clockwise (-45 degrees), click Continue, and then capture the third and final set of images.

  4. The Camera Calibration Tool will process the images and display the following window to notify the user to continue or complete the calibration.

  5. To calibrate another focal length, select Adjust focus / zoom, and click Continue.

  7. Repeat Steps 2-7 until you complete all sets of focal length calibration. (In this tutorial, we have 5 sets of focal length calibration.)

  8. If you did not use another FIZTrack lens encoder to track focus, click Done.
