Mohammad Asiful Hossain, Abdul Kawsar Tushar
2017 arXiv   pre-print
We have mentioned a number of popular contour-based corner detectors in our paper.  ...  Among all these detectors chord to triangular arm angle (CTAA) has been demonstrated as the most dominant corner detector in terms of average repeatability.  ...  DESCRIPTION OF PROPOSED TECHNIQUE We name our proposed technique as Chord Angle Deviation using Tangent (CADT) detector.  ...

A Robust Checkerboard Corner Detection Method for Camera Calibration Based on Improved YOLOX

Guohui Wang, Hao Zheng, Xuan Zhang
2022 Frontiers in Physics  
This paper proposes a robust checkerboard corner detection method for camera calibration based on improved YOLOX deep learning network and Harris algorithm.  ...  Camera calibration plays an important role in various optical measurement and computer vision applications. Accurate calibration parameters of a camera can give a better performance.  ...  We would also like to thank the reviewers for the valuable and constructive comments that helped us improve the presentation.  ...
