Detailed Documentation
In this section, we will establish geometric distortion models and implement distortion correction. The specific methodology involves acquiring coordinate values from template images, then computing transformation model parameters to solve for coefficients in transformation polynomials. This approach typically utilizes computational methods such as least squares fitting to optimize polynomial coefficients, where key functions might include coordinate extraction from calibration patterns and matrix operations for parameter estimation. The primary objective is to achieve more accurate distortion correction, thereby enhancing image quality and measurement precision through systematic mathematical modeling.
