Specific embodiment
Below by way of specific specific example and the embodiments of the present invention is described with reference to the drawings, those skilled in the art
Member can be understood easily the further advantage and effect of the utility model by content disclosed in the present specification.The utility model also may be used
It is implemented or is applied by other different specific examples, the various details in this specification can also be based on different viewpoints and answer
With, carried out under the spirit without departing substantially from the utility model it is various modification and change.
Fig. 2 is the system architecture diagram for the vena metacarpea identification device that palm position can be accurately positioned in the utility model one kind.Such as
Shown in Fig. 2, the vena metacarpea identification device 10 of palm position can be accurately positioned in the utility model one kind, comprising:
At least two or more than two projector 1, the projector 1 be separately positioned in the surrounding of vena metacarpea identification module 2,
Each projector 1 is used to for respective visible light pattern being projected in the palm of user, so that user is according to the visible light projected
Pattern determines the correct placement position of palm in the registration of the centre of the palm, i.e., each visible light pattern is overlapped i.e. so that throwing in the centre of the palm
The position when pattern of shadow is relatively clear is then correct palm placement position, and coincidence here includes whole coincidence or part
It is overlapped, whole be overlapped refers to that the visible light pattern of each projector is identical, and each visible light pattern of projection is completely coincident, example
If the visible light pattern of each projector is circular pattern, as shown in figure 3, projection it is multiple it is circular can be by the circle of light pattern
It is overlapped, certainly, each visible light pattern can also be each section of a pattern, such as a round part respectively, partially overlap
Then refer to that the visible light pattern of each projection constitutes a complete pattern (such as round), such as uses two projectors, visible light figure
Case is semicircle respectively, is partially overlapped, and refers to that the diameter of two semicircular patterns is overlapped, forms full circle.
In the utility model specific embodiment, projector 1 uses Miniature projector, and Fig. 4 is then that the utility model is specific
The detail structure chart of projector 1 in embodiment.As shown in figure 4, projector 1 include visible light source 101, transparency 102 and
Projecting lens assembly 103, wherein visible light source 101 is used to provide the visible light of projection to realize that visible light pattern projects, and throws
It can be projected by projecting lens assembly 103 and light source 101 after visible light pattern is installed on film 102.It is practical at this
In novel specific embodiment, projector 1 need to be separated, since the center spacing distance size of projector 1 influences user's observation
The susceptibility of projected image overlapping, therefore, the centre distance of every two projector 1 should be greater than as far as possible vena metacarpea identification module 2 and want
The 10% of the palm distance (object distance) asked, in the utility model specific embodiment, the object distance of vena metacarpea identification module 2 is
50mm-100mm, therefore the centre distance of every two projector 1 should be greater than 5mm as far as possible.
Illustrate the utility model below by way of two projectors: as shown in Fig. 2, two projectors are respectively arranged at the palm
The two sides of hand vein recognition module, the centre distance of two projectors are greater than the palm distance (object distance) that vena metacarpea identification module requires
10%, since the object distance of vena metacarpea identification module is 50mm-100mm, projector centre distance is greater than 5mm, two projections
Visible light pattern on device is identical, and the angle requirement of two projectors projection: the picture centre being projected out must be put with palm
When optimum position (palm is placed at correct object distance, and the normal in the centre of the palm and the normal of vena metacarpea identification module optical center are overlapped)
The centre of the palm be overlapped, while two images integrally to be also overlapped.That is, by the two projectors that two width are similarly visible
Light pattern is projected on the palm of user, and user is by adjusting hand palm centre of the palm position, when two width projected images are in centre of the palm weight
It closes, i.e., when coincidence pattern is relatively clear, which is then correct palm placement position.
Vena metacarpea identification module 2 carries out at identification for acquiring the vena metacarpea image of user's palm, and to vena metacarpea image
Reason, to achieve the purpose that through living things feature recognition.Due to vena metacarpea identification module 2 Image Acquisition and identifying processing with it is existing
Vena metacarpea acquisition technique it is identical, it will not be described here.
As it can be seen that the utility model by increase around vena metacarpea identification module two (or more) projector, using double
(or multiple) pattern projective iteration may make user to get rid of the bracket of positioning palm, and can be accurately positioned the position that palm is put
It sets.
In conclusion the vena metacarpea identification device of palm position can be accurately positioned by using visible in the utility model one kind
Light projection pattern is overlapped using two or more visible light patterns in the centre of the palm, realizes and do not depend on bracket and be accurately positioned hand
Slap the purpose of position.
The utility model solves the disadvantage that the existing vena metacarpea identification device using bracket, in the case where not using bracket
Guarantee the correct of palm placement position, while the precision being imaged is identical with using the vena metacarpea identification device of bracket, and can open up
Open up the following application scenarios of vena metacarpea:
1, the prior art, can not be using supine reading manner due to not having visible light guidance positioning, and this is practical
It is novel, it can be inverted vena metacarpea identification device, so as to which vena metacarpea identification is applied to outdoor open-air environment, without load
Heart rain and snow weather；
2, existing vena metacarpea identification device can not be applied due to that can not minimize, mobile with bracket in movement
On POS, and vena metacarpea module can be installed on other mobile terminals, such as move POS due to not using bracket by the utility model
On machine, as long as user stretches out palm, it will be seen that light pattern is projected in user's centre of the palm using the user of POS machine, and keep pattern clear
It is clear to collect high-precision vena metacarpea information, it is convenient for the user to use.
The above embodiments are only illustrative of the principle and efficacy of the utility model, and not for limitation, this is practical new
Type.Anyone skilled in the art can repair above-described embodiment under the spirit and scope without prejudice to the utility model
Decorations and change.Therefore, the rights protection scope of the utility model, should be as listed in the claims.
