Description
Technical field
The utility model is related to a kind of finger vein image acquisition device, more particularly to a kind of hand handled based on forerunner
Refer to vein image acquisition device, belong to human-body biological authentication techniques field.
Background technology
With the development and progress of society, information technology has gradually been melted into the work and life of people, to the mankind
While society offers convenience, safety and secrecy to information it is also proposed requirement that is higher, updating.However, generally making at present
Authentication identifying method, such as password, password, key, ID cards, exist easily damage, forget, being stolen, being decrypted etc. and ask
Topic, the daily life given people brings many troubles, or even causes great property and life potential safety hazard.According to statistics, in U.S.
State has nearly hundred million dollars of welfare fund to be palmed off by others to get every year, just have every year in only Shenzhen of China 2,000,000 RMB with
On social insurance be falsely taken, equally existing personation identity in other countries such as France, Britain causes the feelings of heavy economic losses
Condition.Meanwhile, traditional identification technology can not realize the authentication to terrorist, particularly each international politics since " 911 " event
Mansion is all in biological support identification technology energetically, and the safe examination system of China's first Olympic Games just uses biological identification technology.Therefore,
The demand that human-body biological identification technology caters to the epoch turns into the study hotspot in this century, while also bringing huge economic city
.
After the slow growth of experience, biological identification technology was now into fast-developing stage, 2007 to 2013
During 6 years, the world market scale average annual growth rate of biological identification technology is 21.7%, and this increases in whole world most industries
Rate really belongs to exception under the contrast less than 5%, and in 2015, biological identification technology world market economic scale reached 13,000,000,000 dollars,
The year two thousand twenty will be added to 25,000,000,000 dollars, and the average annual growth rate in this 5 years is approximately 14%.In a word, continued to develop in technology of Internet of things
Overall background under, with the continuous maturation of biological identification technology, its market prospects is inestimable.
Vein identification technology is that the hemoglobin in human vein can absorb the light principle of certain wavelength,
When irradiating vein using the light in the wave-length coverage, vein image is obtained, then the image of acquisition is analyzed and processed, most
Obtained vein pattern value is matched in database afterwards, realizes and vein identification technology, which is divided into, to be differentiated to the identity of individual
Palm vein identification technology, Palm-dorsal vein recognition technology and finger vein identification technology, because the blood vessel of palm is thinner, simultaneously
Fat ratio is thicker, and obvious palmprint information can also influence the IMAQ of vena metacarpea in addition, thus the vessel information collected compared with
It is less and unstable；Hand back vein information is enriched the most, and skin is than relatively thin, in that context it may be convenient to carries out IMAQ, but adopts
Concentration must clench one's fists and could obtain vein image, and then the fixation of the back of the hand is turned into problem, it is easy to collection position occur
Movement and deflection, influence discrimination；Finger vena information is relatively enriched, and finger position is fixed well, the compact simplicity of harvester,
Skin fat is less, easily transmits near infrared light, can very easily collect steady and audible vein image, therefore, finger
The collection and identification of vein image are current biological identification technology study hotspots both at home and abroad.
In this context, study a set of intellectuality and refer to vein identification device, unit identification can be carried out, also can be with meter
Calculation machine or the interconnection of other control systems, such as：Gate inhibition, examine business system etc., with higher confidentiality, security, it is antitheft, examine
It is diligent, safely, examine in terms of business there is important application value and important meaning.At present, the collection and knowledge of finger venous image
It is not more have that image conformity is poor, intensity of illumination not enough, the problem of finger can not be completely covered, image irradiation distributing homogeneity
Poor, the segmentation interface of influence finger areas and background area causes Vein Verification information unobvious, causes picture quality can not
Meet and require, and in image acquisition process, extraneous natural light can also produce influence to illumination patterns, and on the finger of people
IMAQ quality is influenceed due to easily speckling with greasy dirt and sweat.
