Update log

  • 22-02-01: Code is coming soon...

  • 21-06-15: You can run the Demo_calib.py for calibration demo on synthetic data after modifying the path set in it (The demo data is saved in \CCS\Code\demo_data).

  • 21-07-19: RANSAC-based calibration by Zhang's method is added as Calib.calib_RANSAC_OpenCV().

TODO LIST

  • code release.
  • README complete.

File Folder Configuration

    How to do calibration on real camera data?

    I have a webcam I would like to perform calibration on. Calibration on real data was mentioned in the paper, but there doesn't seem to be away to implement that using the code.

    Thanks in advance!
