Description

Technical Field

[0001] This utility model relates to the field of facial recognition technology, specifically a facial scanner with a supplementary lighting structure. Background Technology

[0002] In today's era of rapid digital and intelligent development, facial scanning technology is widely used in many fields such as access control systems, identity verification, and payment terminals due to its convenience and security.

[0003] However, in actual use, existing face scanners often suffer from unsatisfactory scanning and recognition results due to poor lighting conditions. Traditional face scanners often rely on supplementary lights to illuminate the user's face directly. However, the light from these supplementary lights is simply illuminating from one direction, which can easily lead to shadows due to the unevenness of the user's face. The presence of shadows not only reduces the clarity of the face image but may also interfere with the scanning device's recognition of facial feature points, resulting in an increased scanning and recognition error rate and affecting efficiency and security.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] Please see Figures 1 to 5 This utility model embodiment provides a face scanner, which is applied to scenarios involving facial scanning and recognition at night or in low light conditions. This embodiment improves the structure of the face scanner to provide the advantages of supplementary lighting and focused light. Specifically, taking facial scanning and recognition in dark environments as an example, as a preferred solution in this embodiment, the face scanner is specifically a face scanner with a supplementary lighting structure, capable of supplementing light to the face while simultaneously using diffracted light to provide supplementary lighting from different angles.

[0028] Please see Figures 1 to 5 This utility model provides a technical solution: a face scanner with a supplementary lighting structure, which is used for face scanning and recognition in scenarios such as night or poor lighting.

[0029] It includes an imaging mechanism 1, two reflection mechanisms 2, and a camera mechanism 4, wherein:

[0030] Two reflective mechanisms 2 are rotatably connected to both sides of the outer surface of the imaging mechanism 1;

[0031] The reflection mechanism 2 includes a fixed base 201, an adjusting plate 202, a positioning base 203, and a reflective film 204. One end of the adjusting plate 202 is rotatably connected to the inner wall of the fixed base 201, and the other end of the adjusting plate 202 is rotatably connected to the outer wall of the positioning base 203 via a rotating shaft. The two sides of the outer surface of the reflective film 204 are detachably connected to the outer surfaces of the fixed base 201 and the positioning base 203, respectively.

[0032] The camera mechanism 4 is positioned above the display mechanism 1.

[0033] In this embodiment, one end of the fixed base 201 is rotatably connected to the imaging mechanism 1 via a positioning shaft 102, providing an installation base for the adjustment plate 202 and the reflective film 204. It can rotate at an angle, working in conjunction with the adjustment plate 202 to adjust the reflection angle of the light. By adjusting the rotation angle, the direction of the reflected light can be changed, achieving flexible adjustment of the light reflection angle. This, combined with the adjustment plate 202, better reflects diffuse light onto the user's face. One end of the adjustment plate 202 is rotatably connected to the inner wall of the fixed base 201, and the other end is rotatably connected to the outer wall of the positioning base 203 via a rotating shaft. Through its own rotation, it forms an arc-shaped space, causing the reflective film 204 to bend and conform to the arc shape, allowing the reflective film 204 to better reflect diffuse light in a centered manner and concentrate the light. The light is reflected onto the user's face, reducing light dispersion and improving light utilization. The positioning base 203 is rotatably connected to the adjustment plate 202 and, together with the fixing base 201, fixes the reflective film 204 to ensure the stability of the reflective film 204. This ensures that the reflective film 204 can be stably fixed according to the arc shape formed by the adjustment plate 202, thereby achieving effective light reflection. The outer surfaces of the reflective film 204 are detachably connected to the outer surfaces of the fixing base 201 and the positioning base 203, respectively. Under the action of the adjustment plate 202, the fixing base 201, and the positioning base 203, the reflective film 204 is bent into an arc shape to reflect diffused light and concentrate the diffused light onto the user's face, increasing the light intensity on the face, reducing shadows caused by facial contours, and improving the clarity of the facial image.

[0034] In the above embodiments, as a preferred embodiment, the display mechanism 1 includes a display screen 101, two positioning shafts 102, and a protective shell 103. The two positioning shafts 102 are respectively fixedly installed on both sides of the outer surface of the display screen 101, and the protective shell 103 is fixedly installed on the rear side of the outer surface of the display screen 101. The display screen 101 is used to display the results of face scanning and related information, such as whether the recognition was successful or not, and the identity information of the recognized object, providing intuitive visual feedback to operators or users and facilitating timely understanding of the scanning situation. The positioning shafts 102 are fixedly installed on both sides of the outer surface of the display screen 101, serving to position and support the reflection mechanism 2, ensuring that the reflection mechanism 2 can be stably and rotatably connected to the display mechanism 1, ensuring the connection stability and rotational flexibility between the reflection mechanism 2 and the display mechanism 1, and providing a basis for subsequent light reflection adjustment. The protective shell 103 is fixedly installed on the rear side of the outer surface of the display screen 101, protecting the display screen 101 from external impacts, dust, moisture, etc., extending the service life of the display screen 101, and improving the overall reliability and stability of the equipment.

[0035] In the above embodiment, as a preferred solution, the reflective mechanism 2 further includes four fixing bolts 205. The four fixing bolts 205 are threaded through the four corners of the outer surface of the reflective film 204, and one end of the four fixing bolts 205 protruding from the reflective film 204 is threadedly connected to the outer surface of the fixing seat 201 and the positioning seat 203. The fixing bolts 205 are threaded through the four corners of the outer surface of the reflective film 204, and the reflective film 204 is threadedly connected to the outer surface of the fixing seat 201 and the positioning seat 203, so as to realize the detachable installation of the reflective film 204, which facilitates the installation and removal of the reflective film 204, and makes it easy to replace, clean or maintain the reflective film 204.

[0036] In the above embodiment, as a preferred solution, the top of the protective shell 103 is provided with an adjustment mechanism 3. The adjustment mechanism 3 includes a guide cylinder 301, anti-slip washers 302, and an adjustment rod 303. The two anti-slip washers 302 are respectively fixedly installed below the outer surface of the guide cylinder 301. The lower part of the outer surface of the guide cylinder 301 is rotatably connected to the top of the protective shell 103 via a pivot. The adjustment rod 303 is slidably connected to the inner wall of the guide cylinder 301. The lower part of the outer surface of the guide cylinder 301 is rotatably connected to the top of the protective shell 103 via a pivot, providing a sliding guide for the adjustment rod 303, allowing the adjustment rod 303 to slide on its inner wall, thereby realizing the sliding adjustment of the adjustment rod 303 and adjusting its position. The height of the camera assembly 4 is adjusted to accommodate users of different heights or different scanning scenarios. Anti-slip washers 302 are fixedly installed below the outer surface of the guide cylinder 301, increasing the friction between the guide cylinder 301 and the protective shell 103. This prevents the guide cylinder 301 from rotating freely and ensures that it remains stable after being adjusted to a suitable angle. This prevents angle changes due to slight external contact, ensuring the stability of the camera assembly 4. An adjusting rod 303 is slidably connected to the inner wall of the guide cylinder 301. The height of the camera assembly 4 is adjusted by sliding within the guide cylinder 301, allowing it to be adjusted to a suitable height according to actual needs, thus improving the accuracy and adaptability of face scanning.

[0037] In the above embodiment, as a preferred option, the adjusting mechanism 3 further includes a fastening bolt 304 and a pad 305. The fastening bolt 304 is threaded through the outer surface of the guide cylinder 301, and one end of the fastening bolt 304 is fixedly connected to the outer surface of the pad 305, with the outer surface of the pad 305 pressing against it. By tightening or loosening the fastening bolt 304, the degree of pressure of the pad 305 against the adjusting rod 303 is controlled. When the fastening bolt 304 is tightened... At position 4, the pad 305 presses against the adjusting rod 303, fixing the adjusting rod 303 in its current position. When the fastening bolt 304 is loosened, the adjusting rod 303 can slide inside the guide cylinder 301, thus locking and unlocking the position of the adjusting rod 303. The pad 305 and the end of the fastening bolt 304 that passes through the guide cylinder 301 are fixedly connected. Under the action of the fastening bolt 304, the pad presses against the adjusting rod 303, which serves to fix the position of the adjusting rod 303, ensuring that the adjusting rod 303 can be stably fixed after being adjusted to a suitable height, preventing the adjusting rod 303 from sliding during use, and ensuring the stability of the height of the camera mechanism 4.

[0038] In the above embodiments, as a preferred option, the camera mechanism 4 includes a rotating base 401, a bracket 402, a camera 403, and a limiting bolt 404. The rotating base 401 is threadedly connected to the top of the adjusting rod 303. The bottom of the bracket 402 is fitted onto the top of the rotating base 401. The camera 403 is rotatably connected to one side of the bracket 402 via a rotating shaft. The limiting bolt 404 is threaded through one end of the rotating shaft and located on the other side of the bracket 402. The rotating base 401 is threadedly connected to the top of the adjusting rod 303, providing a mounting base for the bracket 402. The horizontal angle of the bracket 402 can be adjusted by rotation, allowing the camera mechanism 4 to be angled horizontally, expanding the scanning range of the camera 403, and improving the flexibility of face scanning. The bottom of the bracket 402 is fitted onto the top of the rotating base 401, providing support and a mounting position for the camera 403. The rotating base 401 can... The camera 403 is rotated horizontally to ensure its stability and allows for horizontal angle adjustment, facilitating face scanning. The camera 403 is rotatably connected to one side of the bracket 402 via a pivot and is used to capture facial images for face scanning and recognition. It obtains clear and accurate facial images, providing data for subsequent recognition processing and is the core component for achieving face scanning and recognition. A limiting bolt 404 is threaded through one end of the pivot and located on the other side of the bracket 402. Tightening or loosening the limiting bolt 404 controls the vertical rotation angle of the camera 403 and fixes it in a suitable position. This ensures the camera 403 can be adjusted to a suitable angle and stably fixed in the vertical direction, preventing arbitrary rotation during use and ensuring the accuracy of face scanning.

[0039] In the above embodiments, as a preferred option, the camera mechanism 4 further includes a universal joint 405 and a fill light 406. The bottom of the universal joint 405 is fixedly connected to the top of the camera 403, and the bottom of the fill light 406 is fixedly connected to the top of the universal joint 405. The bottom of the universal joint 405 is fixedly connected to the top of the camera 403, and the top is fixedly connected to the fill light 406. This allows the fill light 406 to be angled in multiple directions, enabling the fill light 406 to adjust the illumination angle according to actual needs, better cooperate with the camera 403 to provide fill light to the user's face, and improve the fill light effect. In low-light environments, the fill light 406 provides additional illumination to the user's face, and in conjunction with the reflection mechanism 2, further reduces the influence of shadows, enhances the light intensity on the face, improves the clarity of the facial image, and reduces the scanning and recognition error rate caused by insufficient light.

[0040] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that provides control.
