Abstract
The invention discloses a VTM machine based on iris identification; the VTM machine comprises the following units: an iris identification device used for identifying iris characteristics and sending characteristic constants to a database; the database used for storing characteristic constants and comparing inputted characteristic constants with stored characteristic constants; a main controller used for controlling the iris identification device to locate and identify an iris, receiving a database contrast result, and sending an ID authentication result to a host computer according to the contrast result. The advantages are that the VTM machine can utilize human eye physiology changes on lights, and can adjust the light brightness of an oriented light source so as to obtain the iris dimensional changes. A fake eye cannot adjust dimensions at will, and cannot be affected by light intensity. A simple light source arrangement can provide a fake eye identification function, and the needed cost only takes 10% of existing equipment; no precise camera is needed, thus greatly reducing the equipment volume, and saving space.

Specific embodiment
According to Fig. 1,2, a kind of VTM machine based on iris identification of the present invention, include iris identification device,
For identifying iris feature, and eigenvalue is fed back to data base；Data base, for storing eigenvalue, and the feature by input
Value is compared with the eigenvalue of storage；Master controller, for controlling iris identification device to Iris Location in identification；Receiving data
The comparison result in storehouse；Identity authentication result is sent to host computer according to comparison result. described iris identification device, including：Pseudo-
Directional light sources are exported random brightness signal by eye detector unit；Obtain iris dimensions change；When iris dimensions change and directional light
Source brightness flop is judged as true eye to when corresponding to, otherwise for pseudo- eye；Directional light sources, for sending the orientation of brightness-adjustable to eyeball
Light；Image acquisition unit, for obtaining eyeball image after pseudo- eye detector unit is judged as true eye；Iris Location unit, uses
In boundary alignment is carried out to the iris in eyeball image, extract iris image；Feature extraction unit, for extracting iris image
In iris feature.
Because the relatively pseudo- eye of human eye has pupil automatic regulation function to adapt to different light intensity environment, adjust pupil in eyeball
Iris naturally-occurring change in size when size, when showing as platycoria, iris internal-and external diameter can increase.Otherwise contracted pupil
When iris internal-and external diameter also can reduce.Although variable quantity less, is sufficient to catch its situation of change by photographic head.Due to
Pseudo- eye does not have the ability of this change adjustment, and it is true that therefore simple light source setting and size detection just can effectively distinguish eyeball
Puppet, equipment cost is very cheap.
After showing as eyeball entrance video scope during application, photographic head catches eyeball automatically, and opens directional light sources, by light
Line is directed at pupil direction.The pseudo- eye detector unit brightness flop function random to directional light sources output, brightness flop function controls
The brightness of directional light sources increases and reduces.Iris situation of change in detection eyeball simultaneously, if situation is reduced in the expansion of iris
Consistent with the brightness increase and decrease situation in brightness flop function, then judge that this eyeball is true eye, otherwise for pseudo- eye.It is being defined as very
The iris feature that can be carried out next step after eye extracts and compares, not only simple but also accurate.
Pseudo- eye detector unit can also control the light source direction of directional light sources, increases the identification ability of pseudo- eye further.People
Eye is inherently automatic when light is mobile to be moved toward light, therefore outside detection through hole scaling, can also detect
In eyeball, whether the direction of iris movement is consistent with light source change direction, if being unanimously judged as true eye, otherwise for pseudo- eye.
In order to preferably make eyeball that light source is produced with physiological reaction, the wavelength of directional light sources adopts most sensitive two kinds of human eye
