SYSTEM AND METHOD OF IDENTIFYING RAILWAY NUMBER PARTS ON THE IMAGE OF THEIR SURFACES WITH STAMPS AND MARKING SIGNS Russian patent published in 2019 - IPC G06K9/72 G06K5/00 B61L25/00 

FIELD: computer equipment.

SUBSTANCE: method of identifying railway number parts on the image of their surfaces with stamps and marking signs, performed by means of a processor, in which performing automatic marking of images of surfaces with identification information of predetermined number parts by selecting areas and elements containing identification information; method includes constructing a feature set with calculating parameters which characterize mutual arrangement of identification information elements for each marked image; storing the marked images and constructed feature sets for each image in the reference images storage and the index database, respectively; method includes searching for a set of features formed based on an image of an identified numbered part in an index database, thereby obtaining a list of candidate parts most similar to the identified part by a feature set.

EFFECT: high accuracy and speed of identifying railway number parts.
