FIELD: measuring technology.
SUBSTANCE: invention relates to control and measuring equipment and can be used to measure the geometric parameters of cylindrical objects, in particular uranium fuel pellets, composite fittings, cable products, wire in the production process. The problem is solved by the fact that in the optoelectronic method for measuring the diameter of a cylindrical object, in which an optoelectronic meter is equipped with an optically coupled radiation source and a multi-element photodetector, while a measured cylindrical object and two calibration objects with known diameters are located between the radiation source and a multi-element photodetector, simultaneously with measuring the visible diameter of a cylindrical object, the visible diameters of the calibration objects are measured, and the final value of the diameter of the cylindrical object is calculated, using the obtained values of the measured visible diameters of objects and the linear dependence of the visible diameter on the known ones.
EFFECT: creation of an optoelectronic method for measuring the diameter of a cylindrical object, providing high measurement accuracy and automatic calibration of the measuring complex.
