Technical Field

[0001] This utility model relates to the field of facial recognition technology, specifically to a facial recognition backdrop for improving contrast. Background Technology

[0002] Currently, facial recognition equipment is widely used in airport and train station security checks. By recognizing individual facial features, it enables rapid identity verification and screening, effectively improving the efficiency and accuracy of security checks, and is an indispensable part of the modern security system.

[0003] In existing security checkpoints and high-traffic environments, facial recognition devices are easily affected by the background environment of people or faces in the background, which affects the recognition efficiency and accuracy. Therefore, a facial recognition background screen to improve contrast is proposed. Utility Model Content

[0004] To address the problems in existing technologies, this utility model provides a face recognition backdrop for improving contrast. It provides a backdrop mechanism for venues where face recognition is required, effectively shielding the environment behind the person being recognized, reducing the impact of the environment on face recognition, and thus improving the contrast and accuracy of face recognition.

[0005] The technical solution adopted by this utility model to solve its technical problem is a face recognition backdrop for improving contrast, including a movable base, a green screen, and a rewinding shaft assembly for rewinding the green screen. The rewinding shaft assembly is disposed in the movable base and includes a rotating shaft and a sleeve. The two ends of the rotating shaft are rotatably connected to the movable base through bearings, respectively. The sleeve is sleeved on the rotating shaft, and the two ends of the rotating shaft are provided with spiral springs, which are fixed to the sleeve and the rotating shaft, respectively.

[0006] By adopting the above technical solution, a back screen mechanism is provided for the venue where face recognition is required, consisting of a movable seat, a rewind assembly, and a green screen. This effectively shields the environment behind the person being recognized, reduces the impact of the environment on face recognition, and thus improves the contrast and accuracy of face recognition.

[0007] Specifically, one end of the green screen is fixed to the sleeve, and the green screen is wrapped around the sleeve. The end of the green screen away from the sleeve is fixedly connected to a pull plate.

[0008] By adopting the above technical solution, the back of the person being identified is obscured by a green screen, thereby improving the recognition accuracy of the facial recognition device.

[0009] Specifically, each end of the pull plate is provided with a card, the end of the card is inserted with a plug, and a tension spring is sleeved on the plug. The two ends of the tension spring are connected to the card and the plug, respectively.

[0010] By adopting the above technical solution, the green screen can be pulled out from the movable seat by pulling the plate.

[0011] Specifically, a first upright and a second upright are respectively provided on both sides of the top of the movable seat, and a rotating sleeve is provided at both ends of the top of the movable seat. The shaft ends of the rotating sleeves are rotatably connected to the movable seat through bearings. One end of the first upright is welded to the rotating sleeve at one end of the top of the movable seat, and one end of the second upright is welded to the rotating sleeve at the other end of the top of the movable seat.

[0012] Both the first and second uprights have insertion holes corresponding to the plugs at the ends furthest from the rotating sleeve.

[0013] By adopting the above technical solution, the first and second uprights are rotated and opened on the movable seat through the rotating sleeve. Through the cooperation of the first and second uprights and the plug, the two ends of the pull plate can be fixed on the first and second uprights.

[0014] Specifically, brakeable casters are installed at the bottom corners of the movable seat.

[0015] By adopting the above technical solution, the brakeable casters can improve the flexibility of the overall device in moving around the site.

[0016] The beneficial effects of this utility model are as follows: By using a component consisting of a movable base, a rewind assembly, and a green screen, a back screen mechanism is provided for the venue where facial recognition is required. This effectively shields the environment behind the person being recognized, reducing the impact of the environment on facial recognition, thereby improving the contrast and accuracy of facial recognition. It is highly flexible in use, can be quickly stored, and can be flexibly pushed and transferred in the usage area, greatly improving the overall flexibility of the back screen. It solves the problem that in existing security checkpoints and high-traffic environments, facial recognition equipment is easily affected by the background environment of people or faces in the background, which affects the recognition efficiency and accuracy.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1-5 As shown, the present invention provides a face recognition backdrop for improving contrast, comprising a movable base 1, a green screen 3, and a rewinding shaft assembly 2 for rewinding the green screen 3. The rewinding shaft assembly 2 is disposed within the movable base 1 and includes a rotating shaft 21 and a sleeve 22. The two ends of the rotating shaft 21 are rotatably connected to the movable base 1 via bearings. The sleeve 22 is sleeved on the rotating shaft 21. Both ends of the rotating shaft 21 are provided with spiral springs 23, and the two ends of the spiral springs 23 are fixed to the sleeve 22 and the rotating shaft 21, respectively.

[0026] In use, the movable base 1, the rewind assembly 2, and the green screen 3 provide a movable backdrop mechanism for the venue where face recognition is required. This effectively shields the environment behind the person being recognized, reducing the impact of the environment on face recognition and thus improving the contrast and accuracy of face recognition.

[0027] The present invention also includes that one end of the green screen 3 is fixed to the sleeve 22, and the green screen 3 is wrapped around the sleeve 22, and the end of the green screen 3 away from the sleeve 22 is fixedly connected to a pull plate 4.
