Description
Technical field
The utility model belongs to and utilizes human body biological characteristics to carry out identification and authentication technology field, specifically is meant a kind of device that finger venous image authenticates of gathering.
Background technology
At present, Chang Yong bio-identification has technology such as fingerprint, palm, iris, face contour, sound, signature in the world, wherein, fingerprint recognition has conveniently, reliable and noninvasive advantage, be technical ripe relatively biological identification technology, be most widely used at present.But fingerprint recognition also has following deficiency: some people or colony's fingerprint characteristic seldom do not reach the requirement of filing; Part user can't authenticate because of finger wear; Each fingerprint that uses all can be left a trace, and has the possibility that is replicated utilization.At above many defectives, a kind of new biometric discrimination method-finger vena identification is suggested.
Finger vena identification is the new bio recognition technology that recent development is got up, and it is by extracting the method that finger vein features authenticates.Show through foreign study, finger vena identification refuse sincere and accuracy of system identification all is better than fingerprint identification technology.
Finger vena identification utilizes the characteristics of the infrared light of the haemoglobin absorption 700 ~ 1200nm wavelength region may in the blood, by finger is shone near infrared light, takes the vein pattern that refers to inside, and contrasts with the register information of registering in advance, and authentication in person thus.
But existing finger vein authentication device is to make a video recording to inserting the inner finger of this device.For this reason, because the user must insert finger the inner space of finger vein authentication device obturation, thus the sense of resistance is arranged, and existing finger vein authentication device also exists the excessive problem of volume.
The utility model content
The utility model technical issues that need to address are to provide a kind of can take distinct vein pattern, and finger need not to insert this device inside, and open small-sized finger vein authentication device that can miniaturization.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: open small-sized finger vein authentication device, include the finger placement rack, the finger placement rack is provided with cmos image sensor below finger abdomen position, cmos image sensor is connected to control circuit board, and the sidepiece of described finger placement rack is provided with and can shines the infraluminescence pipe group that places the finger on the finger placement rack from the side.
Described cmos image sensor top is provided with infrared fileter.
Described finger placement rack is provided with the cylindrical convex lens that can carry out optically focused to it in infraluminescence pipe group front.
Described finger placement rack is provided with capacitance type sensor, and capacitance type sensor is connected with control circuit board.
Described finger placement rack is made by light absorbent, and its surface is a frosting.
Owing to adopted above-mentioned structure, the utlity model has following beneficial effect: the finger placement rack is open, and it is inner that finger need not to insert this device, and the user does not have and resists sense; Adopt single-row light source side-irradiation the height of vein authentication apparatus can be reduced greatly, volume has been realized miniaturization, and the inner structure simplicity of design is convenient to extensive manufacturing, assembling, has reduced the power consumption of whole device simultaneously; Easy to use, can guarantee the stability of sample collection, can comparatively accurately obtain the vein blood vessel image of Different Individual, greatly improved the quality of original finger venous image.

Fig. 3 is the side view of open small-sized finger vein authentication device shown in Figure 1.
Fig. 4 is the structural representation of open small-sized finger vein authentication device embodiment two.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Embodiment one
As shown in Figure 1 to Figure 3, the utility model embodiment one described open small-sized finger vein authentication device includes finger placement rack 103, and finger placement rack 103 is used for placing finger 102.Described finger placement rack 103 is made by light absorbent, and its surface is a frosting, and light absorbent is chosen as the inferior luminescent material of black, can avoid like this light through finger placement rack sidewall reflects to cmos image sensor, cause interference to image.Finger placement rack 103 is provided with cmos image sensor 105 below finger abdomen position, cmos image sensor 105 is used to take the finger vena picture.Cmos image sensor 105 is connected to control circuit board 106.Described cmos image sensor 105 tops are provided with infrared fileter 104, and infrared fileter 104 is used for the filtering visible light to be disturbed.The sidepiece of described finger placement rack 103 is provided with and can shines the infraluminescence pipe group 100 that places the finger on the finger placement rack 103 from the side.Infraluminescence pipe group is positioned at the one-sided of finger, and it is 4 that this example uses the infrared tube quantity of infraluminescence pipe group.Infraluminescence pipe group 100 can possess brightness control function, judges the bright dark of light according to the image averaging that collects, and regulates the brightness in infraluminescence source, can both collect the image of high-contrast to the finger of different thicknesses.Described finger placement rack 103 is provided with the cylindrical convex lens 101 that can carry out optically focused to it in infraluminescence pipe group 100 fronts, cylindrical convex lens 101 is used for light-ray condensing preventing that in referring to dorsal surface infrared light from finger contours generation diffuse reflection, can improve picture quality.Described finger placement rack 103 is provided with capacitance type sensor 300, and capacitance type sensor 300 is arranged on the finger tip of finger and refers to the root position, and capacitance type sensor 300 is connected with control circuit board 106.Whether capacitance type sensor utilizes body capacitance to come finger sensing to place on the finger placement rack, 300 pairs of biosomes of capacitance type sensor just respond simultaneously, the advantage that adopts this kind sensor is to have only finger could trigger induction, other object is put finger vena identification authenticate device system into and can not given a response, and whether therefore also can be used for detecting on the placement rack is finger.
Embodiment two
Fig. 4 is embodiments of the present invention two, and in Fig. 4, infraluminescence pipe group 100 is embedded in the finger placement rack 103, oblique fire finger side on the side direction, and the advantage of this embodiment is to make the whole degree of device littler, volume is littler.
When the utility model uses, refer to the back of the body from one-sided irradiation behind the near infrared light process cylindrical convex lens optically focused that infraluminescence pipe group produces, near infrared light reflects along all directions in finger refers to, when running into finger arterial blood red blood cell, Infrared can be absorbed, the vein image of cmos image sensor collection finger, through after a series of algorithm process, the vein pattern that extracts finger is stored and is filed, perhaps with archives in image compare the identification authentication.
In a word; though the utility model has exemplified above-mentioned preferred implementation; but should illustrate; though those skilled in the art can carry out various variations and remodeling; unless such variation and remodeling have departed from scope of the present utility model, otherwise all should be included in the protection domain of the present utility model.
