Description

Technical Field

[0001] The present invention relates to the field of biometrics, and in particular to a vein recognition method and device. Background Art

[0002] Vein recognition refers to the use of infrared cameras with corresponding wavelength ranges to capture the distribution of veins in body parts based on the characteristics of deoxyhemoglobin in venous blood absorbing near-infrared rays or human body radiating far-infrared rays, extract its features after pre-processing, and then match it with pre-stored feature data to determine personal identity. Since the internal vein blood vessel characteristics are not affected by the surface conditions of body parts, vein recognition technology can be used outdoors in complex environments such as rain and strong light. Even if the body parts are dirty or damaged, it can be recognized normally. It has the characteristics of being difficult to copy and high security.

For some application fields that require miniaturization, the light source position of existing vein recognition devices is single. When placed on the body part, such as a finger, it will cause the back of the finger to be dark, the image at the joint to be dark, and the brightness of the front and back of the finger to be uneven, which is not conducive to the subsequent algorithm recognition of the image.

[0037] Example 1

[0038] Before describing further details of various embodiments of the present application, reference will be made to Figure 1 An alternative vein recognition device that can be used to implement the principles of the present application is described below. In its most basic configuration, Figure 1 1 is a structural diagram of a vein recognition device according to an embodiment of the present invention. For the purpose of description, the architecture depicted is only an example of a suitable environment and does not impose any limitation on the scope of use or function of the present application. The device should not be interpreted as Figure 1 There are no dependencies or requirements on any one or combination of components shown.

[0039] like Figure 1 As shown, the vein recognition device provided by the present application includes:

[0040] The housing 30 is configured to house a plurality of light sources 10 .

[0041] In an optional solution, the shell may be a semi-enclosed shell, and the unenclosed portion is used for the insertion and extension of fingers, palms, and backs of hands.

[0042] The above-mentioned multiple light sources can be integrated into one light source module, or integrated into multiple light source modules; the multiple light sources can emit infrared light; the multiple light sources are arranged at any one end of the two ends of the shell.

[0043] The plurality of light sources 10 are arranged to provide light in a plurality of different directions to illuminate the target object.

[0044] In an optional solution, the target object may be any part of the body such as fingers, palms, back of hands, wrists, toes, etc., which is not limited here.

[0045] The above-mentioned multiple lights in different directions shine toward the target object together, so that the brightness of the target object can be uniform.

[0046] For example, multiple light sources can be divided into two light zones, with the light from the first light zone illuminating the fingernails, and the light from the second light zone illuminating the second joints of the fingers, to ensure uniform illumination of all parts of the fingers.

[0047] Of course, in order to provide light in multiple different directions, multiple light sources can be integrated into two light source modules, which are arranged on the shell at different angles to the horizontal plane, and the angle of one light source module to the horizontal plane is larger than that of the other light source module.

[0048] The recognition module 40 is disposed on the housing 30 and is used to collect an image of the target object and recognize vein information in the image.

[0049] In an optional solution, the identification module may be arranged at the other end of the housing opposite to the plurality of light sources.

[0050] Vein recognition mainly uses the structure of veins to identify people. The principle of finger vein recognition is also to use the different absorption characteristics of veins, muscles, and bones to infrared light of specific wavelengths to perform venous angiography. The area with veins absorbs infrared light dimly, while the muscle and bone areas reflect strongly, thus achieving vein angiography. Venous patterns are difficult to forge inside the human body.

[0051] Taking finger vein recognition as an example, refer to Figure 1, one end of the housing 30 carries multiple light sources 10, and the other end carries the identification module 40. The housing 30 is a semi-enclosed structure, and the unenclosed space is used to accommodate the finger to be tested. Multiple light sources 10 provide infrared light from different directions to irradiate the finger to be tested, so that the light density irradiated on the finger is basically the same. The identification module 40 captures the image of the finger and extracts the vein information for identification verification.

[0052] In the above embodiment, the vein recognition device includes: a housing configured to hold a plurality of light sources; a plurality of light sources configured to provide light from a plurality of different directions to illuminate the target object; and a recognition module configured on the housing to capture an image of the target object and recognize vein information in the image. This embodiment, by arranging a plurality of light sources from different directions on the housing to illuminate the target object, solves the technical problem in the related art that the light source position of the vein recognition device is single, resulting in uneven brightness of the image of the target object, which is not conducive to subsequent algorithm recognition, and achieves the purpose of uniform brightness of the captured image.

[0053] It should be noted that the vein recognition device of the present invention can be applied to devices that require identity verification, especially miniaturized electronic devices such as mobile phone terminals, electronic locks, etc.

[0054] Optionally, the housing 30 includes: a guiding mechanism 31 disposed in the middle of the housing, and the guiding mechanism 31 is used to place the target object.

[0055] In an optional solution, the guide mechanism may be arranged at an angle to facilitate placement of the target object on the guide mechanism, while ensuring that the target object is placed stably without deflection or movement.

[0056] Optionally, the housing 30 includes: a first bracket 32 ​​and a second bracket 33 , which are respectively arranged at two ends of the housing 30 , wherein the first bracket 32 ​​is arranged to place a plurality of light sources 10 , and the second bracket 33 is arranged to place the identification module 40 .

[0057] In an optional solution, the first bracket and the second bracket can be arranged at an angle. The first bracket is arranged at an angle so that the multiple light sources can illuminate the target object as much as possible, and the second bracket is arranged at an angle so that the recognition module can capture the target object as much as possible.

[0058] Optionally, the above device further includes: a detection mechanism 60, which is communicatively connected to the guiding mechanism 31 and is used to detect the position of the target object.

[0059] In an optional solution, the above-mentioned detection mechanism is arranged in the shell, and may be a capacitive sensor, a pressure sensor, etc.; the above-mentioned capacitive sensor may be arranged at the end of the guide mechanism or inside the guide mechanism, and be communicated with the guide mechanism; the above-mentioned pressure sensor may be arranged inside the guide mechanism, on the upper surface or the lower surface of the guide mechanism, and be used to detect pressure changes of the guide mechanism.

[0060] Taking a capacitive sensor as an example, the change in capacitance is used to detect whether the target object is placed in place. If the capacitive sensor detects that the target object is placed in the correct position, it will generate a capacitance change value within a certain range, and then notify the controller to light up multiple light sources; if the capacitive sensor detects that the placement of the target object is deviated, it can notify the controller to issue prompt information such as sound and light to prompt the user to re-place it.

[0061] Optionally, the plurality of light sources 10 are divided into at least a first light zone 11 and a second light zone 12, wherein the first light zone 11 forms a first angle with the horizontal plane, the second light zone 12 forms a second angle with the horizontal plane, and the first angle and the second angle are not equal in size.

[0062] In an optional solution, the above-mentioned multiple light sources can be integrated into multiple light source modules, with one light source module corresponding to one light zone; or they can be located in the same light source module and divided into multiple light zones.

[0063] Reference Figure 1 , multiple light sources 10 are integrated in two light source modules, one light source module corresponds to one light zone, namely the first light zone 11 and the second light zone 12. The first light zone 11 is inclined at a certain angle to the horizontal plane, and the second light zone 12 is inclined at a larger angle to the horizontal plane, so as to increase the light emission angle, so that more light can be irradiated to the back end of the finger, solving the problem of dark back end of the collected finger image. At the same time, the position of the light source in the first light zone 11 can also be adjusted to make the overall image brightness uniform, which is conducive to the algorithm recognition and processing of the subsequent image. .

[0064] Optionally, the plurality of light sources 10 are divided into at least a first light zone 11 and a second light zone 12 , wherein the number of light sources in the first light zone 11 is not equal to the number of light sources in the second light zone 12 .

[0065] In an optional solution, the above-mentioned multiple light sources can be integrated into multiple light source modules, with one light source module corresponding to one light zone; or they can be located in the same light source module and divided into multiple light zones.

[0066] like Figure 2 As shown, multiple light sources 10 are located in the same light source module and divided into multiple light zones, namely a first light zone 11 and a second light zone 12. The number of light sources in the first light zone 11 is less than that in the second light zone 12, so as to increase the brightness of the rear end of the finger and solve the problem of dark rear end of the collected finger image.

[0067] Optionally, the plurality of light sources 10 are divided into at least a first light zone 11 and a second light zone 12 , wherein the brightness of the light sources in the first light zone 11 and the brightness of the light sources in the second light zone 12 are not equal.

[0068] In an optional solution, the above-mentioned multiple light sources can be integrated into multiple light source modules, with one light source module corresponding to one light zone; or they can be located in the same light source module and divided into multiple light zones.

[0069] like Figure 3 As shown, multiple light sources 10 are located in the same light source module, and the brightness of the captured image is balanced by reducing the brightness of the first light area and / or increasing the brightness of the second light area to obtain an image effect with uniform brightness. This solution does not need to change the positional relationship and quantity of the multiple light sources 10, but only needs to adjust the brightness of the multiple light sources.

[0070] Optionally, a plurality of light sources 10 are disposed on the housing 30 opposite to a target area of ​​the target object.

[0071] In an optional solution, the above-mentioned multiple light sources can be located in the same light source module and divided into multiple light zones.

[0072] like Figure 4 As shown, multiple light sources 10 are located in the same light source module. By changing the installation position of the light source 10, the light source 10 is installed as close to the rear end of the finger as possible, thereby increasing the brightness of the rear end of the finger and improving the problem of darkness at the rear end of the finger.

[0073] Optionally, the above device further includes: a first filtering mechanism 50, which is disposed between the plurality of light sources 10 and the target object and is used to filter out visible light of the light source.

[0074] In an optional solution, the first filtering mechanism may be arranged on a side of the first bracket close to the target object.

[0075] Optionally, the above device further includes: a second filtering mechanism 20, which is disposed between the guiding mechanism 31 and the identification module 40 and is used to filter out external visible light.

[0076] In an optional solution, the second filtering mechanism can be arranged on the side of the guiding mechanism away from the target object; the second filtering mechanism is mainly used to filter out external visible light, and at the same time prevents foreign matter and dust from entering the recognition module.

[0077] Optionally, the recognition module 40 includes: a collection device 41, which is arranged on the second bracket 33 and is used to collect images; and a controller 42, which is communicatively connected with the collection device 41 and is used to recognize vein information in the image.

[0078] In an optional solution, the acquisition device may include a CCD camera; the controller may be located between the acquisition device and the second bracket, and is used to convert the image captured by the acquisition device into an electrical signal, perform recognition processing, and verify identity; the controller may be a photosensitive chip.

[0079] It should be noted that since the multiple light sources, guiding mechanisms, and vein recognition devices are all arranged at an angle, the optical path can be effectively increased, so that the entire device can obtain more effective information, which is more conducive to the miniaturization of the device.

[0080] In the above embodiment of the present application, the vein recognition device includes: a housing, which is configured to place multiple light sources; multiple light sources, which are configured to provide light from multiple different directions to illuminate the target object; and a recognition module, which is arranged on the housing and is used to collect the image of the target object and recognize the vein information in the image. This embodiment solves the technical problem that the light source position of the vein recognition device in the related art is single, resulting in uneven image brightness of the target object, which is not conducive to subsequent algorithm recognition, and achieves the purpose of uniform brightness of the collected image. It is easy to notice that the guiding mechanism of the above scheme can ensure the stable placement of the target object; the tilted setting of the first bracket and the second bracket can ensure that the recognition module obtains more effective information; the detection mechanism can ensure that the target object is placed in the correct position; the different number, brightness and position of light sources in different light zones can ensure the consistency of brightness of the target object; the first filtering mechanism and the second filtering mechanism filter out the visible light in the light path, and prevent dust from entering the recognition module, realizing the miniaturization application of the entire device.
