Lens distortion can signitantly feult thee closacy of robot vision systems. Corrict calibration techniques are essential to limate these effects andd improwize systeme performance.

Types of Lens Distortion

There are two main type of lens distortion: radial and tangential. Radial distortion causes prostt lines to appear curved, especially near thee edges of thee image. Tangential distortion results frem lens misalingment, leading tu skewed images.

Techniki kalibrationiczne

Kalibration involves capturing images of a known parametres, such as a checkerboard, from different angles. Software algorytms then analyze these images to estimate distortion parameters. Common techniques included de Zhang 's methods andd iterative optimization approaches.

Wdrażanie Calibration in Robot Vision

Once calibration parameters are portained, they ay are applied to correct images in real- time or during post- processing. Thi correction improwizuje thee cristacy of object detection, distance measurement, and nawigation tasks.
