Abstract

A method of local anisotropic features for recognition of symbolic images produced with the help of a laser on the cylindrical surface of the plug of fuel elements is described. The method is based on representation of each pixel of the image by a direction of the dominant orientation of its local vicinities. The value of the recognized symbol is determined by that standard, with which the maximal number of coincidences is obtained. A device for automated reading and recognition of digital information (7 symbols from 0 to 9) with productivity 3 fuel elements in minute is presented, and experimental results confirming the efficiency and reliability ofthe recognition method are given.
