Description

Technical Field

[0001] This utility model is a camera component for a turnstile, belonging to the field of turnstiles. Background Technology

[0002] The camera module of a turnstile is a key component for enabling functions such as personnel identification and behavior monitoring. When a person approaches the turnstile, the camera module captures an image at a preset angle and range. The captured image data is transmitted to the main control board via a data transmission line, where image processing algorithms are used for analysis. In facial recognition turnstiles, feature extraction and comparison are performed on the captured facial images to determine the legitimacy of the person's identity, thereby controlling the opening and closing of the turnstile. Turnstiles are typically installed in outdoor or indoor locations with complex lighting conditions, such as subway entrances and shopping mall entrances. Under direct sunlight, images captured by the camera module may exhibit issues such as being too bright, too dark, or having shadows, affecting image clarity and contrast, and thus reducing recognition accuracy.

Detailed Implementation

[0023] 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.

[0024] Please see Figure 1 , Figure 2 and Figure 4 This utility model provides a technical solution: a camera assembly for a turnstile, including an electrical box 1. A top shell 3 is mounted on the top of the electrical box 1. One side of the top shell 3 is inclined, and a camera 5 and a display screen 4 are mounted on the inclined surface. The lower surface of the top shell 3 is recessed to form a cavity, and an ID card reader 2 is installed in the cavity. The ID card reader 2 is connected to the electrical box 1 by screws. The side of the top shell 3 away from its inclined surface is open. A back cover 10 is mounted on the open side of the top shell 3 by screws. A carrier plate 17 is mounted on the back cover 10 by screws. A cooling fan 16 is mounted on the side of the carrier plate 17 facing the inside of the top shell 3. A heat dissipation hole is opened on the side of the back cover 10 away from the top shell 3. The cooling fan 16 and the heat dissipation hole cooperate to dissipate heat inside the top shell 3.

[0025] See Figures 1-4A U-shaped frame 11 is snapped onto the top shell 3. First threaded sleeves 15 are installed on two parallel sides of the U-shaped frame 11. Clamping screws are threaded into the internal threads of the first threaded sleeves 15, ensuring a stable connection between the clamping screws and the U-shaped frame 11. A detachable column 9 is installed at the center of the upper surface of the U-shaped frame 11. One end of the column 9 has a threaded head 13, and the end of the column 9 away from the threaded head 13 has a threaded blind hole 19. A third threaded sleeve 14 is installed at the center of the upper surface of the U-shaped frame 11. Based on the installation height of the light-shielding plate 6, an appropriate number of columns 9 are selected so that the threaded head 13 on one column 9 is screwed into the threaded blind hole 19 on another column 9. Similarly, the assembly of multiple columns 9 is completed without the need to manufacture columns 9 of different lengths. The threaded head 13 on the lowest column 9 is threaded into the third threaded sleeve 14, completing the assembly of the column 9 and the U-shaped frame 11. An inclined plate 12 is provided on the side of the clamping screw away from the top shell 3. The inclined plate 12 is connected and fixed to the U-shaped frame 11. Under the cover of the inclined plate 12, the clamping screw is prevented from snagging on people's clothing, etc. The U-shaped frame 11 is clamped onto the top shell 3, and then the positioning screw 22 is tightened, thereby restricting the relative position of the U-shaped frame 11 and the top shell 3. This realizes the assembly of the structure formed by the U-shaped frame 11, column 9 and light shield 6 with the top shell 3, making it convenient to not install the light shield 6 in environments where light shielding is not required.

[0026] See Figures 1-4 A horizontal hole 18 is provided on the outer surface of the column rod 9. A screw rod 8 is inserted into the horizontal hole 18. A ball head 21 is installed at one end of the screw rod 8. A ball cover 7 is wrapped around the ball head 21 and is rotatably connected to the ball head 21. The ball cover 7 is connected and fixed to the light shield 6. A second threaded sleeve 23, which is connected to the internal space of the ball cover 7, is installed on the spherical surface of the ball cover 7. A positioning screw 22 is internally threaded to limit the relative position of the ball head 21 and the ball cover 7. Nuts 20 are provided on both sides of the horizontal hole 18 along the length of the screw rod 8. The screw 8 is connected to the threaded connection and inserted into the horizontal hole 18. The position of the screw 8 is adjusted along the horizontal hole 18 according to the relative position of the strong light source and the camera 5, and the angle between the light shield 6 and the screw 8 is also adjusted so that the light shield 6 is positioned between the camera 5 and the strong light source. Then, two nuts 20 are used to limit the relative position of the screw 8 and the column rod 9, so as to block the camera 5 according to the direction of the strong light source. Under the blocking of the light shield 6, the influence of the strong light source on the image acquired by the camera 5 is reduced.
