Description

Technical Field

[0001] The utility model relates to the technical field of vein recognition devices, in particular to a device integrating facial vein and palm vein. Background Art

[0002] Vein recognition technology utilizes the property that deoxyhemoglobin in venous blood absorbs specific near-infrared light. By irradiating the target area with near-infrared light and using an infrared camera with a corresponding wavelength to capture the vein distribution map of the target area, after preprocessing such as normalization and denoising, filtering enhancement, vein pattern segmentation, refinement and repair are carried out, and then its features are extracted, and then identity authentication is carried out. As a natural in-vivo feature live recognition technology, vein recognition technology is extremely difficult to forge and tamper with. Compared with other biometric technologies, vein recognition technology has the characteristics of high anti-counterfeiting, high accuracy, stable characteristics and convenient use.

[0003] Traditional access control devices generally use passwords, IC cards or fingerprints for identity recognition, which are prone to risks such as forgetting passwords, losing IC cards or being forged fingerprints, and can no longer meet the security requirements of users for access control systems. Due to the above characteristics of low false rejection rate, low false acceptance rate and high security, vein recognition technology has currently been widely used in access control systems of various enterprises, institutions, schools, banks, communities, etc. However, existing vein access control devices generally use finger vein authentication or facial vein authentication methods, with a single mode, which limits the use scenarios of vein access control devices.

Specific implementation manner

[0017] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments and the drawings. However, the following embodiments are only the preferred embodiments of the present utility model, not all of them. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present utility model. The specific embodiments of the present utility model will be described below with reference to the drawings.

[0018] Refer to Figure 1-2 , an integrated device for facial vein and palmar vein, comprising: a housing 1, a camera, a recognition module 2 and a control module 3; the camera includes a facial vein acquisition camera 4 and a palmar vein acquisition camera 5, wherein: the facial vein acquisition camera 4 is fixed on the front of the housing 1 and forms a 90-degree angle with the front of the housing 1; the palmar vein acquisition camera 5 is fixed on the side of the housing 1, and the angles with the front of the housing 1 and the side of the housing 1 are both obtuse angles; it should be noted that the palmar vein acquisition camera 5 forms obtuse angles with the front solid surface and the side solid surface of the housing 1; the recognition module 2 is installed inside the housing 1 and is in communication connection with the facial vein acquisition camera 4 and the palmar vein acquisition camera 5; the control module 3 is installed inside the housing 1 and is in communication connection with the recognition module 2.

[0019] The device described in this utility model has both facial vein identity authentication function and palmar vein identity authentication function, and can select facial vein or / and palmar vein for identity authentication according to needs, that is: it can either select a single biometric for identity authentication, or select two biometrics simultaneously for dual-modal identity authentication, improving the usage scenarios of the device. In addition, when the user conducts identity verification in front of the device, they will stand directly facing the device. Therefore, the facial vein acquisition camera 4 is fixed on the front of the housing 1, forming a 90-degree angle with the front of the housing 1, facilitating the facial vein acquisition camera 4 to acquire the user's facial vein image; since the palmar vein acquisition camera 5 is fixed on the side of the housing 1, if palmar vein identity authentication is required at this time, only need to gently lift the hand and place it on the side of the device. Because the facial vein acquisition camera 4 and the palmar vein acquisition camera 5 are placed on different surfaces of the housing, there will be no problem of overlapping of the acquired facial vein image and palmar vein image. Additionally, since the angle between the palmar vein acquisition camera 5 and the front of the housing 1 is an obtuse angle, and the angle with the side of the housing 1 is also an obtuse angle, that is, the palmar vein acquisition camera 5 is set in the direction facing the user, the user's palm does not need to be placed towards the rear of the device. Therefore, when the device is installed on a wall or other device, there is no need to reserve space for palm placement between the device and the wall, improving the convenience of using the device.

[0020] A first through hole 6 is provided above the front of the housing 1, and the facial vein acquisition camera 4 passes through the first through hole 6; a palmar vein acquisition camera mounting portion 7 is provided below the side of the housing 1, and both sides of the palmar vein acquisition camera mounting portion 7 are respectively connected to the front and side of the housing 1. A second through hole 8 is provided on the palmar vein acquisition camera mounting portion 7, and the palmar vein acquisition camera 5 passes through the second through hole 8. By providing through holes on the housing 1 and installing the cameras in the through holes, displacement of the cameras during use is avoided, improving the service life of the device. At the same time, the facial vein acquisition camera 4 is located in the first through hole 6, and the palmar vein acquisition camera 5 is located in the second through hole 8. The settings of the first through hole 6 and the second through hole 8 prevent the imaging areas of the facial vein acquisition camera 4 and the palmar vein acquisition camera 5 from being blocked.

[0021] A first near-infrared lamp 9 communicatively connected to the control module 3 is provided on the periphery of the facial vein acquisition camera 4, and a second near-infrared lamp 10 communicatively connected to the control module 3 is provided on the periphery of the palmar vein acquisition camera 5. The control module 3 can control the first near-infrared lamp 9 and the second near-infrared lamp 10 to emit near-infrared light.

[0022] The facial vein and palm vein integrated device further includes a human-computer interaction module 11 communicatively connected to the control module 3. The human-computer interaction module 11 is installed on the surface of the housing 1 and is placed below the palm vein acquisition camera 5. The facial vein and palm vein integrated device further includes an NFC module 12 communicatively connected to the control module 3. The NFC module 12 is installed on the surface of the housing 1 and is placed below the human-computer interaction module 11. In the present utility model, the human-computer interaction module 11 is a numeric keypad. The user can set the device password or NFC identification and perform identity verification by password or NFC, which is more flexible and has a wider range of usage scenarios.

[0023] A battery connected to the control module is further provided inside the housing 1 of the facial vein and palm vein integrated device to supply electrical energy to the camera, the identification module, the control module, the first near-infrared lamp, the second near-infrared lamp, the human-computer interaction module, and the NFC module, ensuring the normal operation of the device.
