Description

Technical Field

[0001] The utility model relates to the technical field of biometric acquisition tablets with iris-assisted acquisition brackets, and specifically relates to a biometric acquisition tablet with an iris-assisted acquisition bracket. Background Technique

[0002] The iris is a flat, circular ring-shaped film in the middle layer of the eyeball wall, located between the cornea and the lens, and can be seen through the cornea. Commonly known as the "black eye", there is a small circular hole in the center, called the pupil, through which light enters the eye. The iris is mainly composed of connective tissue, containing pigments, blood vessels, and smooth muscles. The color of the iris varies depending on the amount and distribution of pigments, and generally includes several types such as black, blue, gray, and brown. An iris acquisition instrument is a professional instrument for taking iris pictures.

[0003] Currently, the mainstream binocular iris acquisition instruments in the industry are all separated from the host and connected for use through a USB data cable. Such products must be used in conjunction with the host, which is inconvenient to use and carry. For other portable terminals integrated with iris acquisition modules, due to the inability to fix the acquisition distance and the inability to achieve stable handheld operation, it ultimately leads to the inability to be applied to large-scale biometric registration acquisition projects to collect high-quality iris images. If an external iris acquisition instrument is connected to a computer or a tablet computer using a USB data cable connection method, there is a risk of connection interruption due to connection detachment during work, and the host and the acquisition instrument are not integrated in design, which is inconvenient to carry. The overall device is heavy and prone to jitter, resulting in very low acquisition efficiency, and usually the quality of the acquired images cannot be guaranteed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a biometric acquisition tablet with an iris-assisted acquisition bracket, which solves the problems of being unable to fix the acquisition distance and being unable to achieve stable handheld acquisition mentioned in the background technique. The bracket adopts a human eye perimeter ergonomic structure, making it fit better with the eye, enabling it to efficiently and directly collect high-quality images, and the overall biometric acquisition tablet can be stably magnetically fixed on the bracket, ensuring the stability of image acquisition and the fixed acquisition distance.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A biometric acquisition tablet with an iris-assisted acquisition bracket, including a bracket. The bracket has two iris acquisition-assisted lens barrels on the left and right. Four magnets I are embedded and installed inside the lens barrels. Four magnets II are fixedly installed on the back of the biometric acquisition tablet corresponding to the magnets on the bracket. The four magnets I on the bracket correspond to the four magnets II on the back of the biometric acquisition tablet and are connected by magnetic attraction.

[0007] Preferably, the bracket and the screw post are integrally injection-molded structures.

[0008] Preferably, a lanyard hole is formed in the side surface of the bracket.

[0009] Preferably, the end of the bracket away from the magnet adopts a human eye perimeter ergonomic structure.

[0010] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows:

[0011] The bracket of the present utility model is used in cooperation with a biometric collection tablet. The end of the bracket away from magnet one adopts a human eye perimeter ergonomic structure, making the bracket fit more closely to the human eye, avoiding the shaking factor of hand-held, enabling it to efficiently and directly collect high-quality images, and the overall structure can magnetically fix the biometric collection tablet stably on the bracket, ensuring the stability of image collection, and the collection distance is fixed. Through the provided lanyard hole, the whole is more convenient to carry. It solves the problems that the iris collection distance of a portable biometric collection terminal is not fixed and it is difficult to obtain high-quality iris images due to the shaking of hand-held collection operations. By adding a collection auxiliary bracket, the collection distance can be fixed, avoiding the instability problem of hand-held, and greatly improving the collection efficiency and the quality of the collected pictures.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0020] Please refer to Figures 1-6 , a biometric collection tablet with an iris-assisted collection bracket, including a bracket 1. There are two lens barrels 3 for iris collection assistance on the left and right of the bracket 1. Four magnets 4 are embedded and installed inside the lens barrel 3. Four magnets two 7 are fixedly installed on the back of the biometric collection tablet 6 corresponding to the 4 magnets of the bracket. The four magnets of the bracket 1 correspond to the four magnets two 7 on the back of the biometric collection tablet 6 and are magnetically connected.

[0021] Specifically, the bracket 1 and the screw post 2 are an injection-molded integrated structure.

[0022] In this embodiment: The whole is injection-molded, integrally injection-molded, and the production method is simple.

[0023] Specifically, a lanyard hole 5 is opened on the side of the bracket 1.

[0024] In this embodiment: By passing the lanyard through the lanyard hole 5, the whole can be put around the neck or held in the hand through the lanyard, which is convenient for carrying.

[0025] Specifically, the outer end of the bracket 1 away from the magnet adopts a human eye perimeter ergonomic structure.

[0026] In this embodiment: In actual work, the bracket 1 can fix the distance of iris collection. The bracket 1 fits very closely with the forehead and orbital parts of the person being collected, and the best collection position can be easily obtained, and the shaking factor of holding by hand is effectively avoided, achieving the purpose of quickly collecting high-quality iris images.

[0027] Working principle: The iris collection assistance bracket 1 is used in conjunction with the biometric collection tablet 6. The portable bracket 1 can be matched according to the actual working scenario. When iris collection is required, the operator only needs to easily place the bracket 1 on the iris module part of the biometric collection tablet 6. The 4 groups of magnets one 4 can automatically align through magnetic attraction to fix the bracket 1 on the back of the biometric collection tablet 6. When the bracket 1 is fixed, the person being collected aligns the eyes with the bracket 1 and stares at the iris window lens of the biometric collection tablet 6. When the infrared light is on, open the eyes and wait for 1 - 2 seconds. The application system will prompt that the iris image collection is successful. When the iris image collection is completed, the operator can easily remove the bracket 1 from the back of the biometric collection tablet 6.
