A "tracker" for automatic camera calibration within the Biotracker. It utilizes the camera calibration functions of OpenCV (OpenvCV example).
- Download and print a chessboard, e.g. the chessboard pattern of the OpenCV example
- Load video file, a series of images or a camera device with this chessboard
- Select the "Chessboard" view to determine whether the chessboad corners are correctly detected
- Select at least 10 frames (this number is arbitraty and hardcoded :P) by pausing at the frame and pressing the "Add Frame" button
- Push the "Calibrate" button and selec the "Rectified Image" view to control whether calibration is good enough
- Export camera matrix by pushing "Save Calibration"
