FIELD: information technology.
SUBSTANCE: marking elements, which form marking symbols together, are applied on the surface of an object in a given order. The marking elements are in form of a fusion of irregularities on the surface or depressions with a given shape and dimensions on the surface with depth which is greater than the depth of operational damages on the surface of the marked object. For each of the marking symbols, in given points near boundaries of the marking region, additional marking elements are applied, based on which recognition of the recorded image is automatically adjusted. Near the additional elements, areas on the surface are left unmarked, based on which the mode for processing images in the marking region is adjusted with regard to taking into account the state of the surface of the object. During recognition adjustment, the code structure is oriented based on a priori known arrangement of the recorded additional elements.
EFFECT: high stability of operation of a direction-finder and reduced susceptibility to self-excitation of the circuit of the direction-finder.
