Tsai's Classic Camera Calibration Program in MATLAB Language

According to user requirements, I will expand the original text while maintaining its core concepts and inserting new technical content.

Tsai's classic calibration program represents a fundamental camera calibration methodology implemented in MATLAB. This implementation typically involves key steps such as: extracting corner points from calibration patterns, computing homography matrices, estimating intrinsic parameters (focal length, principal point, skew coefficient), and determining extrinsic parameters (rotation matrix and translation vector).

The MATLAB implementation generally utilizes built-in functions for image processing (like corner detection algorithms) and matrix operations for solving linear equations during parameter estimation. The calibration process often follows a two-step approach: first solving linear parameters through least-squares estimation, then refining results using non-linear optimization techniques like Levenberg-Marquardt algorithm to minimize reprojection errors.
