CCDN: Checkerboard Corner Detection Network for Robust Camera Calibration

no code implementations10 Feb 2023 Ben Chen, Caihua Xiong, Qi Zhang

Aiming to improve the checkerboard corner detection robustness against the images with poor quality, such as lens distortion, extreme poses, and noise, we propose a novel detection algorithm which can maintain high accuracy on inputs under multiply scenarios without any prior knowledge of the checkerboard pattern.
