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

See ./demo_data/demo_normal.


Workflow


  • Distortion Correction
    If your images suffer from severe radial lens distortion, you are recommended to perfrom distortion correction as follow.
    To be continue ...

  • Feature Extraction Use our network combined with surface fitting algorithm to extract chessborad features and achieve sub-pixel accuracy.
