Lens distortion is a common issue in computer vision applications that can affect the exacty of image analysis. Corretting this distortion is essential for precise measurements and reliable results. This article explicains the types of lens distortion and metods to correcord them.

Types of Lens Distortion

There are two primary typs of lens distortion: radial and tangential. Radial distortion causes heatt lines to o appear curvek, especially near thee edges of thee image. Tangential distortion contribution actuls whes the lens is not perfectly aligned with thae image sensor, leading to skewed images.

Methods for Corretting Lens Distortion

Calibration typically applics capturing images of a known pattern, such a checkerboard, to estimate distortion parametrs. These refrakters are then used t o undistort images.

Calibration Process

Te calibration process involves setral steps:

  • Captura multiples images of a calibration pattern from different angles.
  • Detect Increure points in each image.
  • Komputní distortion parametrs using calibration algoritmy.
  • Aplikujte ty parametrys to undistort accordent images.

Software libraries like OpenCV providee tools to soperate this process, making it accessible for various applications.
