Adaptive double iris and facial image recognition machine

Abstract

The invention discloses an adaptive double-iris and facial image register recognizing machine which comprises a DSP (Digital Signal Processor) embedded microprocessor, an image encoder, a stepping motor and a database, wherein the DSP embedded microprocessor is connected with the image encoder, the stepping motor and the database; the image encoder is connected with IR (iris) cameras, a color camera and an FPGA (Field Programmable Gate Array) programmable logic controller; the database is connected with the FPGA programmable logic controller and a PAL (Programmable Array Logic) encoder; a level isolation and conversion driving module is arranged between the stepping motor and the DSP embedded microprocessor; the stepping motor is connected with the color camera by virtue of a rotating device; the DSP embedded microprocessor is connected with an infrared LED array and a display interface. The adaptive double-iris and facial image register recognizing machine can be used for automatically detecting and tracking faces and eyes, improvement is performed on the basis of existing equipment, a mode that the equipment is searched passively by human bodies is changed into human-computer interaction to adapt to each other, and single display of an iris image is changed into simultaneous display of a double-iris image and a facial image.

Description

[0001] Technical field: [0002] The invention relates to a record recognition machine, in particular to an adaptive double iris and facial image record recognition machine. [0003] Background technique: [0004] Encrypted identification technologies such as keys, passwords, and magnetic cards that people are already familiar with bring us convenience, but also because of their inherent deficiencies—all of which are artificially pre-set, objectively, they are easy to be stolen, imitated, lost, and forgotten. Achilles' heel. These defects have caused and are causing great losses to people, which requires us to find better means of identification to solve the increasingly important problem of who you (me, he) are in social activities. Using the inherent differences in biological appearance of the human body for identification—that is, biometrics—can fundamentally solve the problem of acquired identity information. So biometric technology has aroused great interest. [0005] A...

AI Technical Summary

Problems solved by technology

The existing problems are: (1), in order to meet the requirements of simultaneous use by people of different heights, the installation height of iris recognition equipment is generally relatively low

This forced unnatural posture adaptation does not conform to the physiological characteristics of people standing upright and looking up; at the same time, without support, using one eye at close range to adapt to the shooting area regulated by the equipment is also in line with people's daily life. The habit of viewing the target does not match; (2), iris recognition equipment generally only displays the iris image of the registrant during the work process, but does not display the face (face shape) image, so its intuition is poor

Does not conform to people's habitual thinking mode
