On, infrared ray passes through saturating infrared fileter II 18 after the scattering inside the first tested finger 19, through saturating infrared fileter II
Reflection of the 18 filtered infrared lights again through plane total reflection mirror 20, then by infrared after optical concave lens 22 and convex lens 23
Camera 26 obtains the vein image of the first tested finger 19.
Similarly, the infrared ray that infrared LED array I 1 and infrared LED array II 2 issue passes through slit I 5 and slit II 6 respectively
It shines on the second tested finger 27, infrared ray is identified through finger venous image again after the scattering inside the second tested finger 27
Device 29, to obtain the vein image of the second tested finger 27.
In the specific embodiment of the invention, infrared LED array I 1, infrared LED array II 2, infrared LED array III 3 and red
Outer LED array IV can be made of LED light either LED chip patch respectively.The quantity of LED is depending on the size of LED.Its
In, each infrared LED lamp in infrared LED array can be by adjusting the electric current of infrared LED lamp or using other general
Mode adjusts infrared LED intensity of light, and the tune of the intensity of the infrared LED lamp of different location is carried out according to finger-joint position
Section, because being easier light transmission at finger-joint, if using intensity same as the non-joint of finger at finger-joint
Light can make the brightness of joint in the vein image acquired by infrared camera 26 can be larger, it is quiet to will lead to finger in this way
The brightness irregularities of arteries and veins figure, as shown in Fig. 8 left figure, so that influencing the image procossing of subsequent finger vena identification.Present invention tool
Slit in body embodiment is different from traditional loophole, in the specific embodiment of the invention, is adjusted according to finger-joint position
The intensity of each infrared LED, the light that infrared light is issued along each slit I 5, slit II 6, slit III 7 and slit IV 8
Intensity is different, the available infrared light for being more suitable human finger hand vein recognition, it is hereby achieved that brightness is more uniform
Finger venous image.
It, as shown in Figure 9, can be in the slit I 5 and slit II 6 that infrared light is passed through in the specific embodiment of the invention
Between the side of slot I 15 be provided with protrusion 35, accordingly can also be close in the slit III 7 and slit IV 8 that infrared light is passed through
The side of medial launder II 17 is provided with protrusion 35, setting protrusion 35 can stop portions from the infrared light of slit pass through finger watch
Slit is passed through after the reflection of face and is directly entered infrared camera, to reduce the interference of these light finger vein images.Institute simultaneously
The protrusion 35 of setting can be used for the located lateral of tested finger 19,27, reduce because transverse shifting and the rotation of finger and
Influence the efficiency of hand vein recognition.
In embodiments of the present invention, mouse further includes the usb hub 31 and mouse USB line being arranged in inside mouse body
32.As shown in figure 4, the vein image of mouse instructions signal, tested finger 19,27 is by usb hub 31 by mouse USB line 32
It is transferred to computer, it can realize the function of conventional mouse, and human finger vena recognition function may be implemented.For being safely
Number requires the application of relatively high mobile payment, can use the vena recognition function of two fingers simultaneously, be known with improving
Other safety coefficient.The lower application of safety coefficients such as logging in for PC can be only with one of hand vein recognition
Device is to reduce the manufacturing cost of mouse, as the mouse shown in fig. 5 with finger vena identification function.
Obviously, the mouse in the specific embodiment of the invention is also possible to wireless mouse as shown in FIG. 6, and wireless mouse includes
Usb hub 31 and wireless transmitter, wherein the vein image of tested finger 19,27 is equally equal just as mouse instructions signal
Computer is transferred to by wireless transmitter by usb hub 31.
In the specific embodiment of the invention, the selection of vein identification device can be according to the habit of user right-hand man, can be with
It is that vena recognition function is had at mouse left button 101, it can also be to have hand vein recognition at right mouse button 102.Infrared light is logical
The width of the size of the slit 5,6,7,8 crossed, plane total reflection mirror and saturating infrared fileter 16,18 depends on practical application field
It closes.Safety coefficient requires relatively high mobile payment to can choose long slit, wide plane total reflection mirror 20 and saturating infrared absorption filter
Mating plate 16,18 guarantees to obtain more human finger venous informations, improves the safety of mobile payment.
Each of infrared LED array I 1, infrared LED array II 2, infrared LED array III 3 and infrared LED array IV
LED light can be by adjusting the electric current of LED light or adjusting the intensity of each LED lamplight using other general modes, this
In invention specific embodiment, the intensity of corresponding each LED lamplight can be adjusted according to the joint position of tested finger 19,27,
See Fig. 7, for the LED intensity close to tested 19 joint position of finger than darker, the LED far from finger-joint position is brighter.Due to
Light transmission is easier at finger-joint, so can make if using the light of intensity same as the non-joint of finger at finger-joint
The brightness for obtaining joint in the vein image acquired by infrared camera 26 can be larger, as shown in the left figure of Fig. 8, can thus lead
The brightness irregularities of finger vena figure are caused, so that influencing the image procossing of subsequent finger vena identification.
And in specific embodiments of the present invention, the LED light in infrared LED array can be adjusted according to the position of finger-joint
LED intensity is saved, thus, the intensity difference for the light that the infrared light of infrared LED array transmitting is launched along respective slit can obtain
To the infrared light of human finger hand vein recognition is more suitable, so that the more uniform finger vena figure of brightness ratio is obtained, such as Fig. 8 right figure
It is shown, convenient for the image procossing of subsequent finger vena identification.
The principle that human finger vena recognition function in the embodiment of the present invention uses class reflective, is penetrated with transmission-type and side
The principle of formula has essential distinction.Technical solution of the present invention can not need mobile tested finger 19,27, can disposably obtain hand
The vein pattern of finger does not need to acquire vein pattern of several vein images splicing to obtain finger, improves finger vena knowledge
Other efficiency and accuracy.According to the convenience or habit of user, human finger hand vein recognition function is provided at left button 101
Can, human finger vena recognition function is perhaps equipped at the right key 102 as shown in Fig. 5 or 6 or on two keys of left and right all
Equipped with human finger vena recognition function, covering scope of the invention is belonged to.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
