Description
Technical field
Patent of the present invention belongs to field of optical device technology and electric equipment field, relates in particular to the iris capturing equipment that a kind of user's of utilization self feed back is cooperated with on one's own initiative.
Background technology
Iris recognition technology is current a kind of identity recognizing technology commonly used, and the first step of its work is exactly obtaining of iris image, also is the step of comparison difficulty simultaneously, needs the integrated application of light, mechanical, electrical technology.Because the special nature of iris: area little (the about 11mm of mean diameter), different ethnic group color distortions are big, and general image capture method can't be shot the iris image that can be used for discerning.Iris recognition must adopt bigger camera lens of magnification and initiatively illumination.Westerner's iris color is more shallow, visible illumination just can, and Asians's iris color is darker, must adopt infrared illumination just can obtain distinct image.
The iris image obtains equipment and is divided into contact and contactless two kinds.Initial equipment is contact, mainly comprises initiatively illumination, camera lens and annex, and imager chip etc., not necessarily have feedback assembly.The contact acquisition system generally adopts the shell of the closed cavity of tubular as collecting device, with isolated environment light.In tubular cavity rear end cameras with fixed focus is installed, visible light is installed in the inside of tubular cavity or/and infrared light supply.When gathering iris image, eyes of user abuts against the cavity front end, initiatively triggers the collection button imaging of camera.The advantage of this contact system is guiding eyes aiming than being easier to, and illumination designs fairly simple, is not easy to be subjected to the influence of external environment light.But there is inborn weakness in this collecting device, and promptly each collection all needs the user to contact with collecting device, and the contact collection has brought the hidden danger of health aspect simultaneously.
In order to solve the problem of contact, contactless iris capturing equipment has appearred, by initiatively illumination, feedback assembly, camera lens and annex, and the first-class formation of making a video recording, this moment, user distance iris capturing equipment had certain distance, and as 25cm or farther, equipment judges subscriber station is arranged before equipment by range finder module or graphical analysis, start working, perhaps equipment is just worked always.Equipment judges in the image that collects whether iris is arranged when work, and points out the user to cooperate iris capturing, behind the satisfied image of acquisition, the iris in the image is carried out feature extraction and comparison, thereby finish the identification of user identity.And iris capturing equipment develops into the equipment of gathering two eyes simultaneously from the equipment of initial single eyes of collection.Owing to be the distant range iris collection, and the area of human eye iris is less, harvester must adopt the bigger camera lens of magnification could obtain can be used in the iris image of identification, make that the camera acquisition visual angle is less, the user must make eyes be positioned on the certain location, this position is positioned at the field depth of video camera, the energy blur-free imaging, and be in the effective lighting scope.It is unusual difficulty that user cooperating equipment under without any the situation of auxiliary alignment methods is gathered iris image.Therefore the guiding user who has occurred various feedback assemblys on the iris capturing equipment realizes aiming at.
Feedback assembly is normally used to have audio feedback or/and visual feedback.Audio feedback refers to voice suggestion that the user sends according to equipment and adjusts posture and the position of oneself, as equipment can point out " more forward, more backward, more left, more to the right ".Audio feedback be by equipment according to adopted at that time information such as image the user is carried out prompting initiatively.And being thing that the user sees according to oneself, visual feedback adjusts oneself position.People have added feedback devices such as mirror on iris capturing equipment, help user's realization aligning up and down in every way, in the reflective mirror of iris recognition equipment, see two eyes of oneself simultaneously as the iris recognition equipment requirements user of Panasonic, move the pilot lamp that also has the guiding user to move on the equipment then all around by the voice suggestion user.The iris recognition equipment of LG such as LG3000 (monocular equipment) require the user to watch minute surface attentively, the feasible iris that can in the black line frame of minute surface, see oneself, and LG4000 (binocular iris recognition equipment) this require the user in minute surface, to see the eyes of oneself, and a luminous point that makes minute surface transmit later is arranged in the place between the eyebrows position of own mirror eyes.The product of other companies of market, as Iritech, OKI etc. all adopt similar design.The feedback device assisted user of the similar mirror of this employing aim at we be called passive visual feedback, because the user directly aims at according to oneself picture of reflection, and the user has different being accustomed to eye, different major-minor eyes can cause user oneself to think having aimed at but in fact gathers phenomenon less than suitable image.Iris recognition product on the market all is the equipment that adopts this passive vision feedback method at present.
Because the passive vision feedback can't inform whether user's eye position is suitable by vision, people continue to launch research in this respect, and United States Patent (USP) " Image Input Device " and Chinese patent " non-contact type self-feedback iris image acquisition device " all propose the monocular iris recognition equipment of novel employing active vision feedback.Feedback initiatively camera acquisition to content feed back to the user with the form of image, the user can adjust the position of self as looking in the mirror, the passive vision feedback of front face is different, that the user sees is exactly the result who gathers, alleviated the influence with eye custom or the like, alignment result has improved many than the iris recognition equipment that adopts the passive mode visual feedback.But existing active adjustment mode all is at simple eye iris recognition technology, the user is with an eye alignment, slanting head and unconscious possibly, and because just may form various angles on two canthus physiology of each one eyes with level, whether be slanting head, thereby cause problems such as alignment difficulties information is inaccurate according to the image of eyes if can't differentiate.
