Abstract

The article presents the subject of calibration of the image recorded by the vision system. The optical system of vision systems uses lenses that introduce distortion during image recording. The first distortion is the perspective distortion resulting from the way the video system is built in relation to the measuring plane on which the object is located. The second group is optical distortion - optical aberrations that affect the shape and colour of the image of objects recorded on the sensor matrix. Both distortion groups should be removed from the image to measure the geometrical parameters of the object. This is accomplished using the image calibration operation shown on the selected example in this work.
