Description

Technical Field

[0001] The utility model belongs to the technical field of face recognition, and specifically relates to a face recognition device. Background Technique

[0002] The research on face recognition technology began in the early 1990s and was initially mainly applied to video analysis and crowd statistics. With the continuous improvement of computing power and the rapid development of technologies such as image processing and pattern recognition, face recognition technology has gradually matured and been applied in a wider range of fields. Especially in the early 2010s, the emergence of deep learning technology has significantly improved the accuracy and speed of face recognition technology, thus triggering the widespread application of this technology.

[0003] The face recognition devices commonly existing in the current market, due to their fixed angle design, are difficult to flexibly adapt to the diverse heights of users, which greatly limits the universality of their applications and the comfort of the user experience. For users with relatively short heights, they may have to jump or stand on tiptoe to try to align their faces with the recognition area; while for users with relatively tall heights, they may need to bend down or even lean forward. Such operations are not only laborious and embarrassing, but more importantly, they greatly affect the accuracy and efficiency of face recognition. Unnatural postures such as leaning forward or jumping will cause changes in the expressions and angles of the user's face, and these changes often exceed the training scope of the face recognition algorithm, thus increasing the difficulty and error rate of recognition. When the facial features of the user are distorted due to posture changes, the algorithm may not be able to accurately capture the key feature points, resulting in recognition failure or misjudgment. Therefore, it is necessary to improve and optimize it. Summary of the Utility Model

[0004] To solve the problems raised in the above background technique, the utility model provides a face recognition device.

[0005] To achieve the above object, the utility model provides the following technical solution: A face recognition device includes a recognition screen, a flip plate is fixedly installed on the back of the recognition screen, an L-shaped block is fixedly installed on one side of the flip plate, a sliding block is slidably installed on the side of the L-shaped block away from the flip plate, a rotating column is rotatably installed on the side of the sliding block away from the recognition screen, the sliding block is slidably installed on the outer surface of the rotating column, and a rotating column housing is rotatably sleeved on the outer surface of the rotating column.

[0006] Preferably, a fixing plate is fixedly installed on one side of the rotating column housing, four fixing blocks are fixedly installed on the surface of the fixing plate close to the flip plate, a connecting rod is hingedly installed on the top of the fixing block, a pressing block is fixedly installed at one end of the connecting rod, and a clamping rod is fixedly installed at the other end of the connecting rod.

[0007] Preferably, long rods are fixedly installed inside both ends of the flipping plate, and the two long rods penetrate through the flipping plate towards both ends, and the two ends of each long rod are respectively clamped with a clamping rod.

[0008] Preferably, two long rod fixing blocks are fixedly installed on the side of the flipping plate close to the flipping plate, and the two ends of the two long rod fixing blocks are respectively attached to the two ends of the two long rods.

[0009] Preferably, a motor is fixedly installed at the bottom of the rotating column housing, and the output shaft of the motor extends into the interior of the rotating column housing and is fixedly connected to the rotating column.

[0010] Preferably, a fixing column is hinged at the bottom of the identification screen, a motor fixing block is fixedly installed on the side of the fixing column, and the motor fixing block is fixedly installed outside the motor.

[0011] Preferably, four springs are fixedly installed between the opposite surfaces of the fixing plate and the connecting rod, and the four springs are all fixedly installed on the side of one end of the connecting rod away from the extrusion block. The other end of the connecting rod penetrates through the long rod fixing block and is fixedly connected to the clamping rod.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] When the motor of the present utility model is started, the output shaft of the motor drives the rotating column to rotate. When the rotating column rotates, due to the groove path design on the surface of the rotating column, the rotating column drives the sliding block to move on the surface of the rotating column when rotating. While the sliding block moves linearly under the influence of the rotating column, it drives the L-shaped block to flip following the movement of the sliding block, so that the sliding block drives the flipping plate to flip, thereby realizing the flipping of the identification screen. Compared with the traditional device, by setting the flipping mechanism, the face recognition device can adjust the angle according to people of different heights. This flipping mechanism can automatically adjust the angle of the identification screen according to the height of the user, ensuring that no matter the user is tall or short, the best recognition field of view can be maintained. This user-friendly design greatly improves the usability and comfort of the device. Since the identification screen can be automatically adjusted to the best viewing angle, it reduces the recognition errors or failures caused by viewing angle deviation, thereby improving the accuracy and efficiency of face recognition. This is particularly important for application scenarios such as security monitoring and access control management, and can ensure the accuracy and rapidity of identity verification.

Specific embodiments

[0021] 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 creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figures 1 to 6 shown, the present utility model provides a face recognition device, including an identification screen 2. A flip plate 3 is fixedly installed on the back of the identification screen 2. An L-shaped block 4 is fixedly installed on one side of the flip plate 3. A sliding block 5 is slidably installed on the side of the L-shaped block 4 away from the flip plate 3. A rotating column 6 is rotatably installed on the side of the sliding block 5 away from the identification screen 2. The sliding block 5 is slidably installed on the outer surface of the rotating column 6. A rotating column housing 7 is rotatably sleeved on the outer surface of the rotating column 6.

[0023] By starting the motor 8, the output shaft of the motor 8 drives the rotating column 6 to rotate. When the rotating column 6 rotates, due to the groove path design on the surface of the rotating column 6, the rotating column 6 drives the sliding block 5 to move on the surface of the rotating column 6 during rotation. While the sliding block 5 moves linearly under the influence of the rotating column 6, it drives the L-shaped block 4 to flip following the movement of the sliding block 5, causing the sliding block 5 to drive the flip plate 3 to flip, thereby realizing the flipping of the recognition screen 2. Compared with traditional devices, by setting up a flipping mechanism, the face recognition device can adjust the angle according to people of different heights. This flipping mechanism can automatically adjust the angle of the recognition screen 2 according to the user's height, ensuring that whether the user is tall or short, the best recognition vision can be maintained. This user-friendly design greatly improves the usability and comfort of the device. Since the recognition screen can be automatically adjusted to the best viewing angle, it reduces recognition errors or failures caused by viewing angle deviation, thereby improving the accuracy and efficiency of face recognition. This is particularly important for application scenarios such as security monitoring and access control management, and can ensure the accuracy and rapidity of identity verification.

[0024] As Figures 1 to 6 shown, one side of the rotating column housing 7 is fixedly installed with a fixing plate 9. Four fixing blocks 12 are fixedly installed on the surface of the fixing plate 9 close to the flip plate 3. A connecting rod 13 is hingedly installed at the top of the fixing block 12. One end of the connecting rod 13 is fixedly installed with a pressing block 14, and the other end of the connecting rod 13 is fixedly installed with a clamping rod 16.

[0025] By setting the fixing plate 9, when the flip plate 3 is flipped under the mutual cooperation of a series of accessories, through the setting of the fixing plate 9 and the fixing blocks 12, when the two ends of the flip plate 3 respectively press against the pressing block 14 during the flipping process, under the mutual cooperation of the connecting rod 13, the pressing block 14, the spring 15 and the clamping rod 16, when the flip plate 3 respectively flips around the long rod 10, the long rod 10 can be firmly fixed on the fixing plate 9 through the long rod fixing block 11 and the clamping rod 16, ensuring the stability of the operation of the flipping mechanism. This design ensures that the flip plate 3 can maintain a stable center when flipping around the long rod 10, avoiding recognition errors or equipment damage caused by angle deviation, thereby greatly enhancing the stability of the overall structure.

[0026] As Figures 1 to 6 shown, two long rods 10 are fixedly installed inside both ends of the flip plate 3 and the two long rods 10 penetrate through the flip plate 3 at both ends. The two ends of the long rod 10 are respectively clamped with the clamping rod 16; two long rod fixing blocks 11 are fixedly installed on the side of the flip plate 3 close to the flip plate 3, and the two ends of the two long rod fixing blocks 11 are respectively attached to the two ends of the two long rods 10; the bottom of the rotating column housing 7 is fixedly installed with a motor 8, and the output shaft of the motor 8 extends into the interior of the rotating column housing 7 and is fixedly connected to the rotating column 6.

[0027] By providing the long rod 10, when the recognition screen 2 is flipped driven by the flipping mechanism, the recognition screen 2 rotates in two directions respectively around the two long rods 10. Through the cooperative setting of the long rod 10 and the clamping rod 16, the flipping in both directions can be carried out stably. The long rod 10 serves as the axis of rotation of the recognition screen 2, and its design enables the recognition screen 2 to rotate in two different directions around these two axes, thereby covering a wider range of user groups and usage scenarios. It firmly engages with the long rod 10, thus achieving locking during the flipping process. This locking mechanism effectively prevents shaking or deviation during the flipping process and ensures the smooth progress of the flipping action. By providing the long rod fixing block 11, when the flipping plate 3 starts to flip around the two long rods 10 respectively, the long rod fixing block 11 fixes the long rod 10 and provides stable support for the flipping plate 3 when flipping around the long rod 10, ensuring the stable operation of the flipping mechanism. Through the setting of the rotating column housing 7, when the motor 8 is started, it can stably drive the rotating column 6 to rotate inside the rotating column housing 7, enabling the entire flipping mechanism to operate stably and effectively preventing vibration and deviation generated when the rotating column 6 rotates.

[0028] As Figures 1 to 6 shown, a fixed column 1 is hinged to the bottom of the recognition screen 2, and a motor fixing block 17 is fixedly installed on the side of the fixed column 1. The motor fixing block 17 is fixedly installed outside the motor 8. Four springs 15 are fixedly installed between the opposite surfaces of the fixing plate 9 and the connecting rod 13. The four springs 15 are all fixedly installed on one side of the connecting rod 13 far from the extrusion block 14. The other end of the connecting rod 13 passes through the long rod fixing block 11 and is fixedly connected to the clamping rod 16.

[0029] By providing the motor fixing block 17, when the motor 8 is started, it drives a series of accessories to cooperate and operate, enabling the motor 8 to stably operate inside the motor fixing block 17. The stable operation of the motor 8 ensures the stable operation of the flipping mechanism. By providing the springs 15, when the connecting rod 13 is flipped by the extrusion force of the flipping plate 3 on the extrusion block 14, due to the elastic force of the springs 15, after the connecting rod 13 drives the clamping rod 16 to engage with the long rod 10, the springs 15 rebound to make the connecting rod 13 parallel to the fixing plate 9, thus realizing the release of the long rod 10 and ensuring the stability of the operation of the flipping mechanism.

[0030] Working principle and usage process of the utility model: The operator starts the motor 8, and the output shaft of the motor 8 drives the rotating column 6 to rotate. The rotating column 6 rotates inside the rotating column housing 7, causing the sliding block 5 to slide on the surface of the rotating column 6. The movement of the sliding block 5 drives the L-shaped block 4 to slide on one side surface of the sliding block 5, causing the L-shaped block 4 to drive the flipping plate 3 to move, so that the flipping plate 3 rotates respectively with the two long rods 10 as the centers, causing the flipping plate 3 to drive the recognition screen 2 to rotate. When the flipping plate 3 drives the two long rods 10 to rotate, the two ends of the flipping plate 3 exert pressure on the extrusion block 14, causing the extrusion block 14 to squeeze one end of the connecting rod 13. The connecting rod 13 and the fixed plate 9 squeeze the spring 15, causing the connecting rod 13 to rotate around the fixed block 12. When one end of the flipping plate 3 squeezes the extrusion block 14, the extrusion block 14 squeezes one end of the connecting rod 13, causing the other end of the connecting rod 13 to drive the clamping rod 16 to rise and engage with one end of the long rod 10, so that the centers of the flipping plate 3 when rotating respectively with the two long rods 10 are fixed, making the flipping more stable.
