METHOD OF ADAPTIVE GRADUATION OF RADIAL DISTORTION OF OPTICAL SUBSYSTEM OF TECHNICAL VISION SYSTEM Russian patent published in 2006 - IPC G01M11/02 

FIELD: computer engineering.

SUBSTANCE: method can be used for determination and correction of distortion of optical subsystems of video cameras and technical vision systems which use array image receivers as image receivers. Known method of graduation of technical vision active system is used, which includes introduction of image into computer, determination of radial distortion of lenses. According to invention, circuits are selected and image is subject to binarization; graduation object is selected from objects of working stage; coordinates of central point of graduation object are determined; technical vision system is positioned at n different directions of observations; coordinates of central point of graduation object are determined onto image for n different directions of observation and coordinates of radial distortion are found.

EFFECT: no necessity of usage of special graduation objects for graduation.
