Detailed Documentation

The enhanced Zhang Zhengyou camera calibration method incorporates tangential distortion parameters alongside radial distortion coefficients to achieve higher precision in calibration results. This implementation typically involves using OpenCV's calibrateCamera function with additional distortion parameters (k1, k2, p1, p2, k3) to model both radial and tangential distortions. The calibration process follows a structured workflow: capturing multiple checkerboard images from different angles, detecting corner points using findChessboardCorners, and optimizing parameters through iterative solving. The resulting calibration matrix and distortion coefficients can be directly applied in programs for real-time image correction through the undistort function, making camera calibration practically accessible for computer vision applications.
