Lens Distortion Calibration

Lens distortion calibration involves identifying and correcting the imperfections in images caused by a camera lens. As light passes through different lenses, straight lines may appear curved or bent, especially at the edges. Calibration uses special images or patterns to analyze these distortions, creating a mathematical model of how the lens warps the image. By applying this model, software can adjust the photos to make lines straight and proportions accurate, ensuring the captured image truly reflects reality. This process is essential for high-precision photography, computer vision, and applications requiring geometrically accurate images.
