Robust Fourier-Based Checkerboard Corner Detection for Camera Calibration

A highly accurate and robust deep checkerboard corner detector

“…Ha et al [5] presented a corner detection method based on fitting a monkey saddle point surface directly to the image intensity samples. Fourier transform-based methods such as [6] and [7] have also been proposed. The more recently proposed deep learning-based approach [8][9][10] typically trains deep networks on real checkerboard images with manually annotated ground-truth corner locations, which will invariably introduce additional labelling error.…”
