Description

Technical Field

[0001] The utility model relates to the technical field of biometrics, in particular to a multi-dimensional authenticity verification face recognition all-in-one machine. Background Art

[0002] Biometric technology refers to the close combination of computers with high-tech means such as optics, acoustics, biosensors, and biostatistics principles, and uses the inherent physiological characteristics of the human body (such as fingerprints, face images, irises, etc.) and behavioral characteristics (such as handwriting, voice, gait, etc.) to identify personal identities. With the continuous growth of security needs, face recognition technology has been widely used in fields such as access control and payment verification.

[0003] The biometric system samples biometric features, extracts their features and converts them into digital codes, and further forms these codes into feature templates. Due to the continuous decline in the cost of microprocessors and various electronic components and the gradual improvement of accuracy, biometric systems have gradually been applied to commercial authorization control such as access control, enterprise attendance management system security authentication, and other fields. Biometric features for biometric identification include hand shape, fingerprint, face shape, iris, retina, pulse, auricle, etc., and behavioral features include signature, voice, key pressing force, etc. Based on these features, people have developed various biometric technologies such as hand shape recognition, fingerprint recognition, face recognition, pronunciation recognition, iris recognition, signature recognition, etc.

[0004] The patent document with the publication number CN210324339U, a dynamic face recognition access control all-in-one machine, can automatically track the face of a pedestrian before the pedestrian approaches the access control through the set automatic tracking camera, so as to be able to open the door lock faster, improve the door opening efficiency, save the pedestrian's time, and at the same time, the set access control all-in-one machine is small in volume, convenient for installation and disassembly, and is provided with an anti-theft device that can effectively prevent the door lock from being damaged. The utility model has a simple structure, convenient operation, and strong practicability.

[0005] However, through research, it is found that the existing dynamic face recognition access control all-in-one machine has certain drawbacks when in use:

[0006] The dynamic face recognition access control all-in-one machine performs face recognition work on pedestrians through an automatic tracking camera before the pedestrians approach the access control. In the actual application process, due to overcrowding of people, the processing burden on the camera is relatively large, which may cause system failures, and during the recognition process, people without identity permissions may mix into the queue and pass through by means of stealing and swiping. Compared with traditional face recognition systems, which are vulnerable to fraud means such as photo attacks and video substitutions, there are also certain security risks. Summary of the Invention

Specific implementation manners

[0030] Example 1:

[0031] The multi-dimensional authenticity verification face recognition all-in-one machine, as Figures 1-5 , Figure 7 shown, includes the main body 1 of the face recognition all-in-one machine, two lamp boards 8 respectively arranged inside two corners on the front of the top of the main body 1 of the face recognition all-in-one machine, and two light-shielding cylinders 3 respectively sleeved outside the two lamp boards 8. A camera 5 is arranged on the front of the top of the main body 1 of the face recognition all-in-one machine. A longitudinally arranged light-transmitting arc plate 4 is processed inside the light-shielding cylinder 3. The tops of the two lamp boards 8 are provided with the same driving structure;

[0032] As Figure 3 and Figure 4 shown, the driving structure includes an assembly seat 2. A rack 9 is arranged at the center of the bottom of the assembly seat 2. A sector gear 6 is meshed and connected to one side of the rack 9. The bottom of the sector gear 6 is assembled and fixed with a motor 7. Both ends of the rack 9 are meshed and connected with driven gears 11. When the motor 7 controls the sector gear 6 to rotate and drives the rack 9 to move on one side of the two light-shielding cylinders 3, the two light-shielding cylinders 3 can be synchronously controlled to rotate, which is beneficial to supporting the driving structure to control the two light-shielding cylinders 3 to rotate outside the two lamp boards 8 and switching the orientation of the light-shielding cylinder 3 on the front of the main body 1 of the face recognition all-in-one machine;

[0033] Among them, in order to conveniently connect and fix the driven gear 11 and the light-shielding cylinder 3 so that when the driven gear 11 rotates, it drives the light-shielding cylinder 3 to rotate outside the lamp board 8, as Figure 5 shown, a pin shaft is processed at the center of the top of the light-shielding cylinder 3, and the driven gear 11 is interference-fitted to the outside of the pin shaft, so as to be connected and fixed with the light-shielding cylinder 3, which is convenient for controlling the angle of the light emitted by the lamp board 8 and then emitted through the inside of the light-transmitting arc plate 4;

[0034] Meanwhile, when changing the emission angle of the light and the face of the person to be recognized is in front of the camera 5 (the ways for the camera 5 to recognize facial features include, but are not limited to, biometric technology, infrared sensing technology, and image acquisition technology. The infrared sensing technology can be applied to the temperature detection of the face of the person to be recognized, and judge whether the target is a real person through temperature data), at this time, different light and dark effects will appear on the face, and the recognition work is only for one person to be recognized at a time;

[0035] For the way of stealing other people's head portraits by using photos, videos, etc., there will be a reflection situation when the light changes the angle (mainly due to the influence of media such as glass, paper, and plastic film), and it will not achieve the visual effect caused by the change of the light irradiation angle on the human face, which is conducive to the camera 5 to obtain the correct facial features;

[0036] It should be noted that the camera 5 can also use a binocular fisheye camera to obtain a stereoscopic image, and confirm whether the target is a flat photo through image distortion analysis. Compared with the two light-shielding cylinders 3 with the light-transmitting arc plates 4 and the lamp board 8 located inside the light-shielding cylinders 3 in this application, the use of the lamp board 8 in this application can also achieve a good light supplement effect;

[0037] Such as Figure 1 and Figure 2 As shown, the assembly base 2 includes a suspension plate 201. Columns 202 are integrally formed at the bottoms of both ends of the suspension plate 201, and a storage notch 12 is machined inside one end of the column 202;

[0038] Among them, cylindrical storage cavities are machined at both corners at the top of the facial recognition all-in-one machine main body 1. By inserting the two light-shielding cylinders 3 into the two storage cavities of the facial recognition all-in-one machine main body 1 respectively, and machining notches communicating with the inside of the storage cavities at both corners, after installing the two light-shielding cylinders 3 into the two storage cavities, the light-shielding cylinders 3 can be supported to be exposed to the outside inside the storage cavities, so that the light is emitted from the inside of the light-transmitting arc plate 4 to the outside;

[0039] Secondly, by inserting the two columns 202 into the storage cavities at both corners of the facial recognition all-in-one machine main body 1 respectively, and buckling the columns 202 to the outside of the driven gears 11 through the storage notches 12, when the back surfaces of both ends of the rack 9 are respectively attached to the inner walls of one side of the two storage notches 12, the rack 9 can move inside the two storage notches 12, providing a movable support for the rack 9 on one side of the two light-shielding cylinders 3, which is convenient for the rack 9 to drive the two driven gears 11 to drive the two light-shielding cylinders 3 to rotate respectively.

[0040] The multi-dimensional authenticity verification face recognition all-in-one machine of the utility model sets a camera 5 on the front of the top of the face recognition all-in-one machine main body 1, and lamp boards 8 with light-shielding cylinders 3 sleeved outside are arranged at two corners on the front of the face recognition all-in-one machine main body 1. Since the bright light emitted by the lamp boards 8 is emitted to the outside through the light-transmitting arc plates 4, when the motor 7 controls the sector gear 6 to rotate and drives the rack 9 to move on one side of the two light-shielding cylinders 3, the two light-shielding cylinders 3 can be synchronously controlled to rotate, facilitating the switching of the orientation of the light-shielding cylinders 3 on the front of the face recognition all-in-one machine main body 1, so as to control the angle of the light emitted from the inside of the light-transmitting arc plates 4, thereby irradiating the human face with light at different angles to determine the human face features, and there will be no problem of theft and swiping using photos or videos. Moreover, when multiple people are recognized, there will be no situation of misusing human faces.

[0041] Embodiment 2:

[0042] On the basis of Embodiment 1, as Figure 5 、 Figure 6 shown, this embodiment is the specific structure of the mounting seat 2. A vertical plate 10 is integrally formed at the bottom of one side of the hanging plate 201. A slide bar 13 is assembled and connected to one side of the bottom of the vertical plate 10. A slide seat 15 is slidably connected to the outside of the slide bar 13;

[0043] Among them, when the rack 9 moves inside the two storage slots 12 to provide a moving support for the rack 9 on one side of the two light-shielding cylinders 3, thereby driving the two driven gears 11 to rotate and respectively driving the two light-shielding cylinders 3 to rotate, the side of the slide seat 15 can be assembled and fixed to the rack 9. During the movement of the rack 9, with the cooperation of the slide bar 13 and the slide seat 15, a moving track can be provided for it to ensure that the rack 9 is controlled by the motor 7 and the sector gear 6 to drive the two driven gears 11 to rotate stably;

[0044] Secondly, in order to enable the rack 9 to still be supported to move inside the two storage slots 12 after the slide seats 15 of different lengths are assembled with the rack 9, as Figure 6 shown, a storage strip groove 14 is machined on the bottom surface of one side of the rack 9. By assembling and fixing the slide seat 15 to the inner wall of the storage strip groove 14 and storing the slide seat 15 inside the rack 9, during the movement of the rack 9, it can be ensured that the back surface of the rack 9 fits against the side wall of the storage slot 12 without being interfered by one end of the slide seat 15.

[0045] The multi-dimensional authenticity verification face recognition all-in-one machine of the utility model is provided with a sliding seat 15 and a sliding bar 13 on the back of a rack 9, and the sliding seat 15 can be processed with a storage bar groove 14 inside the rack 9 according to requirements and assembled inside the storage bar groove 14. When the sliding bar 13 is fixedly assembled with a vertical plate 10 at the bottom of a suspension plate 201, when the rack 9 slides outside the sliding bar 13 through the sliding seat 15, it can provide stable support for the rack 9 to be controlled by a motor 7 and a sector gear 6 to drive two driven gears 11 to rotate.

[0046] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
