Zhang Zhengyou Camera Calibration with MATLAB Implementation

This documentation provides detailed specifications for the MATLAB implementation of Zhang Zhengyou's camera calibration method. The compressed package contains the original seminal paper by Zhang Zhengyou, which thoroughly explains the underlying principles and procedural steps of this calibration technique. The included MATLAB program features experimental datasets and corresponding calibration images, enabling users to verify and demonstrate the effectiveness of the Zhang Zhengyou calibration approach. The code implements key algorithms including corner detection on checkerboard patterns, homography estimation, and closed-form solutions for intrinsic/extrinsic parameters. Through this program, users can gain deeper insights into the camera parameter calibration workflow and extend/modify the implementation according to specific requirements. The modular structure allows customization of functions like world-to-image point correspondences and nonlinear optimization for distortion coefficients. This resource serves as both an educational tool and practical foundation for computer vision applications.
