Device for producing images of irises of the eye. The device relates to the technology of protecting different objects from access by unauthorized personnel by means of identification of an individual on the basis of an image of the iris of the eye of said individual and can be used in the diagnosis of the state of organs and functional systems in an organism on the basis of the iris of the eye. The device for producing images of irises of the human eyes is directed to simplifying the design, the use conditions and the possibility for simultaneous production of a plurality of sets of characteristic features, i.e. a plurality of codes, which makes it possible to increase the accuracy and speed of identification of an individual. Said result is achieved in that the device for producing images of irises of the human eye comprises a means 1 for illuminating the iris of the eye in one or more spectral ranges which are close to the visible range, a means 2 for recording the signal reflected from the eyes and a means 4 for processing the images produced, said means comprising a unit 5 for detecting the centres of the pupils of the eyes on the image, a unit 6 for determining coordinates of the eyes relative to a set centre of the display and for constructing a straight reference line connecting the centres of the pupils, a unit 7 for processing the images of the iris of the eye in a normalized coordinate grid with segmentation and isolation of information fields, a unit 8 for generating codes, and a unit 9 for storing said codes. |
