Description

Technical Field

[0001] The utility model relates to the technical field of face recognition, in particular to a face recognition light-filling device in a low-illumination environment. Background Art

[0002] Low-light environment refers to a scene with low light intensity, usually when the light is insufficient for the human eye to comfortably identify objects or for a camera to clearly image. Face recognition is a biometric technology that authenticates identity based on facial features. It is widely used in security monitoring, access control systems, payment verification, personalized services and other fields.

[0003] Existing face recognition devices are usually fixed to a wall or door by bolts, and a fill light is usually provided above the face recognition device. When the light is low, the fill light is turned on to increase the brightness for face recognition. Current face recognition devices are generally exposed to the outside and have no protection or dustproof functions. Dust can easily fall and accumulate on the recognition device, affecting the recognition accuracy and efficiency, and reducing the service life of the recognition device.

[0004] Therefore, it is necessary to design a face recognition fill light device for low-light environments that can protect the recognizer while preventing dust from falling on the recognizer and affecting its use, thereby improving recognition accuracy and efficiency and extending the service life of the recognizer. Utility Model Content

[0005] In order to overcome the shortcomings that current face recognition devices are generally exposed to the outside and have no protection and dustproof functions, dust is easily dropped and accumulated on the recognition device, affecting the recognition accuracy and efficiency, and at the same time resulting in a reduction in the service life of the recognition device, the utility model provides a face recognition fill light device for low illumination environments that can protect the recognition device while preventing dust, prevent dust from falling on the recognition device and affecting its use, improve recognition accuracy and efficiency, and extend the service life of the recognition device.

[0006] A face recognition fill light device in a low-light environment comprises a placement box, a fixed block, a connecting frame, a rotating cover, a fill light, a first torsion spring and an identifier. The placement box is connected to upper and lower fixed blocks on both sides, the placement box is connected to the connecting frame on the upper side, the rotating cover is rotatably connected to the connecting frame, the fill light is connected to the inner side of the rear of the rotating cover, two left and right first torsion springs are connected between the connecting frame and the rotating cover, and the identifier is placed on the placement box.

[0007] Optionally, the placement box is made of acrylic material, which has good weather resistance and durability.

[0008] Optionally, screw holes are provided on the fixing blocks.

[0009] Optionally, the rotating cover is made of transparent material.

[0010] Optionally, a limiting frame and a second torsion spring are also included. The limiting frame is rotatably connected to the rear side of the upper part of the rotating cover. The limiting frame is snap-fitted with the placement box. Two left and right second torsion springs are connected between the limiting frame and the rotating cover.

[0011] Optionally, it also includes a support block, a limiting block and a third torsion spring. The left and right sides of the middle of the placement box are connected to the support blocks, the front of the support blocks are rotatably connected to the limiting blocks, the limiting blocks are in contact with the identifier, and two upper and lower third torsion springs are connected between the support block and the adjacent limiting blocks.

[0012] The utility model has the following advantages: 1. The utility model rotates the rotating cover, the first torsion spring is deformed, the rotating cover is rotated to close, and then the limiting frame is released, the second torsion spring is rotated to restore, and the limiting frame is rotated to reset and engage with the placement box, thereby protecting the identifier and preventing dust from falling on the identifier to affect its use, thereby improving the accuracy and efficiency of identification and extending the service life of the identifier.

[0013] 2. The utility model uses a fill light for fill lighting. The light is illuminated through the rotating cover, and the limiting frame can also be pulled to rotate. The second torsion spring is deformed, so that the limiting frame is separated from the placement box, the first torsion spring rotates to restore, the rotating cover rotates to reset and open, and then the fill light is used for illumination, thereby increasing the brightness, ensuring that the captured facial image is clear, and improving the fill light effect.
