Description
Technical field
The present invention relates to living things feature recognition field, refer to especially a kind of iris identification device.
Background technology
Under the strategy of rejuvenating China by applying scientific and technological advances is guided, the biologies such as fingerprint recognition, palmmprint identification, recognition of face, DNA detection are discerned technology and are widely applied socially, have brought into play in practice vital role.But these technology all have some limitations.For example, the accuracy rate of fingerprint recognition is lower; The lift face of people's face, make up after, None-identified; DNA apparatus expensive, during check fee, expensive etc.Accuracy is high because having for iris recognition technology, the advantage of good stability, high-speed and high-efficiency is approved rapidly widely, yet in the recognition system of medium and long distance, iris identification device still has the shortcomings such as complex structure, error recognition rate are higher, apparatus expensive.
Summary of the invention
The present invention proposes a kind of iris identification device, and structure that can simplification device improves identification accuracy, and reduces the cost of equipment.
Technical scheme of the present invention is achieved in that
A kind of iris identification device, comprise camera module for absorbing iris image, for storing the storer of iris sample, processor module for the iris image receiving being carried out to picture quality screening, feature extraction and comparing with iris sample, described camera module, storer are connected with described processor module respectively, described camera module comprises imageing sensor, and the valid pixel of described imageing sensor is at least 5,000,000.
The present invention is by using camera module picked-up iris image, and processor module carries out picture quality screening, feature extraction and compares with the iris sample on storer iris image, has effectively simplified the structure of iris identification device.That the present invention has advantages of is simple in structure, degree of accuracy is high, equipment cost is cheap.
Preferably, described camera module also comprises camera, and described camera is manual zoom lens or automatic zoom camera lens.Thus, can there is iris image that order picked-up arrives effect more clearly.
Preferably, described camera module also comprises for filtering the optical filter of light.The effect can thus, with overdamping light intensity, restriction vibration plane.
Preferably, described imageing sensor is cmos image sensor or ccd image sensor.Thus, can there is the effect that iris image is converted to usable output signal.
Preferably, on described processor module, be connected with the pilot lamp that is used to indicate duty.The effect can thus, with instruction processorunit module duty.
Preferably, described processor module is provided with RJ45 network interface.The effect can thus, with interconnection network.
Preferably, on described processor module, be also connected with light compensating lamp.The effect can thus, with compensating light illumination.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the schematic diagram of an embodiment of a kind of iris identification device of the present invention;
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
A kind of iris identification device as shown in Figure 1, comprise camera module 1 for absorbing iris image, for storing the storer 3 of iris sample, processor module 2 for the iris image receiving being carried out to picture quality screening, feature extraction and comparing with iris sample, camera module 1, storer 2 are connected with processor module 3 respectively, camera module 1 comprises imageing sensor 103, and the valid pixel of imageing sensor 103 is at least 5,000,000.
In the present embodiment, camera module 1 also comprises camera 102, and camera 102 is manual zoom lens.When the distance between user and camera module 1 changes to some extent, can be by changing focal length, picked-up is iris image more clearly, and in other embodiments, camera 102 can also be automatic zoom camera lens.
Camera module 1 also comprises for filtering the optical filter 101 of light.The effect can thus, with overdamping light intensity, restriction vibration plane.
Imageing sensor 103 is ccd image sensor, and ccd image sensor can convert iris image to usable output signal, and in other embodiments, imageing sensor 103 can also be cmos image sensor.
On processor module 2, be connected with the pilot lamp 4 that is used to indicate duty.The function can thus, with indication iris identification device duty.
RJ45 network interface 5 is installed on processor module 2, by RJ45 network interface 5, can be connected to internet, realize the exchange of data.
On processor module 2, be also connected with light compensating lamp 6, when light is darker, open the effect that light compensating lamp 6 can play compensating light illumination.
During use, subscriber station is in the effective range of camera module 1, open iris identification device, manual adjustments focal length, the iris image that picked-up is arrived is more clear, by ccd image sensor, converts iris image to usable output signal, and processor module 2 receives after iris image signal, iris image is carried out picture quality screening, feature extraction and compared with the iris sample on storer, realize identification user's function.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
