FIELD: optical equipment.
SUBSTANCE: invention can be used to correct radial and tangential distortion in images obtained by digital photo, video cameras and vision systems using matrix image receivers as image receivers. The method for lens distortion compensation is based on the determination of radial and tangential distortion and correction of distortion caused by distortion. The test site is exposed in the form of uniformly distributed concentric circles and radii by means of the camera under study, the coordinates of the polygon nodes are read, the Cartesian coordinates of the images of the test site nodes on the photo matrix are converted into polar coordinates, the coefficients of the mathematical model of distortion are calculated, which is a series expansion, power series and two Fourier series, radial distortion, periodic components of radial and tangential distortion compensation is consistently performed.
EFFECT: reduction in the effect of distortion on image distortion.
