Description

Technical Field

[0001] The present invention relates to the technical field of face recognition, and particularly to a face recognition device for employee management. Background Art

[0002] Face recognition is an advanced biometric technology that performs identity recognition based on the facial feature information of a person. This technology collects images or video streams containing human faces through a camera, and uses algorithms such as deep learning and computer vision to extract and analyze key information such as the facial contour, facial texture, and position of feature points of the face, generates a unique face feature template, and compares it with the face template pre-stored in the database to determine whether it is the same person based on the similarity. Face recognition has advantages such as naturalness, intuitiveness, and non-contact, and is widely used in many fields such as security monitoring, access control systems, attendance management, financial payment, and airport security checks, providing an efficient, convenient, and relatively safe and reliable solution for identity verification.

[0003] If the background where the employee is located is complex, such as having a large number of similar patterns, colors, or dynamic objects, the face recognition device may be interfered with, making it difficult to accurately focus on and recognize the employee's face. At the same time, too strong or too weak light may affect the accuracy of face recognition. Summary of the Invention

Detailed implementation manners

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners. The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.

[0026] Embodiment 1: Use Figures 1-5 A face recognition device for employee management according to an embodiment of the present invention will be described as follows.

[0027] As Figures 1-2 shown, a face recognition device for employee management of the present invention includes a fixing plate 1. The outer surface of the fixing plate 1 is fixedly connected with a device housing 2. The top of the device housing 2 is fixedly connected with a front plate 3. The outer surface of the front plate 3 is fixedly connected with a shielding curtain 4. The inner wall of the device housing 2 is uniformly provided with lighting lamps 5. The top of the lighting lamps 5 is fixedly connected with the inner wall of the device housing 2. The bottom of the device housing 2 is symmetrically provided with face supporting plates 6. The bottom of the face supporting plates 6 is fixedly connected with the bottom of the device housing 2. The inner wall of the device housing 2 is fixedly connected with an identification unit 7.

[0028] When the invention works, an employee needs to open the shielding curtain 4, enter the device housing 2, and place the face on the face supporting plate. Then, the identification unit 7 will identify the employee's face.

[0029] When an employee punches in or out, only one person can enter the device housing 2. At the same time, when punching in or out, the face is supported on the face supporting plate 6, so that the face is at the center of the identification unit 7, which is convenient for the identification unit 7 to only identify your face. If the background where the employee is located is complex, such as there are a large number of similar patterns, colors or dynamic objects, the face recognition device 71 may be interfered, and it is difficult to accurately focus and identify the employee's face. At the same time, lighting lamps 5 are arranged in the device housing 2, which avoids that too strong or too weak light may affect the accuracy of face recognition.

[0030] The specific working process is as follows:

[0031] When working, an employee opens the shielding curtain 4, places the human face on the face supporting plate 6, and makes the face face the identification unit 7, so as to facilitate the subsequent face recognition.

[0032] Embodiment 2: Use Figures 1-5 A face recognition device for employee management according to an embodiment of the present invention will be described as follows.

[0033] As Figure 3 shown, a face recognition device for employee management according to the present invention, on the basis of Embodiment 1, the recognition unit 7 includes a recognition device 71. A support plate 72 is fixedly connected to the top of the recognition device 71. A screw 73 is threadedly connected to the outer surface of the support plate 72. A display screen 74 is fixedly connected to the inner wall of the recognition device 71. A fingerprint plate 75 is fixedly connected to one side of the recognition device 71 close to the display screen 74. A camera mechanism 76 is fixedly connected to the outer surface of the recognition device 71.

[0034] When performing face recognition, fingerprint recognition can also be performed.

[0035] The support plate 72 is fixedly connected to the inner wall of the device housing 2 through the screw 73. The camera mechanism 76 is located between the two face plates.

[0036] As Figure 4 shown, the camera mechanism 76 includes a high-definition camera 761. A camera 762 is fixedly connected to the outer surface of the high-definition camera 761. A support plate 763 is fixedly connected to the recognition device 71 close to the camera 762. A micro motor 764 is fixedly connected to the outer surface of the support plate 763. A rotating shaft 765 is fixedly connected to the output end of the micro motor 764. A cover plate 766 is fixedly connected to the outer surface of the rotating shaft 765. A cleaning mechanism 767 is rotatably connected to the inner wall of the cover plate 766.

[0037] When the high-definition camera 761 collects the faces of employees, the micro motor 764 will drive the rotating shaft 765 to rotate, so as to drive the cover plate 766 to move away from the camera 762. When the camera 762 is not working, the cover plate 766 will wrap the entire camera 762, thus preventing foreign impurities from adhering to the camera 762 and affecting face recognition.

[0038] One side of the high-definition camera 761 away from the camera 762 is fixedly connected to the outer surface of the recognition device 71.

[0039] As Figure 5 shown, the cleaning mechanism 767 includes a rotating shaft 7671. A rotating handle 7672 is fixedly connected to one end of the rotating shaft 7671. A support plate 7673 is fixedly connected to the other end of the rotating shaft 7671 away from the rotating handle 7672. Support bars 7674 are uniformly arranged on the outer surface of the support plate 7673. One end of each support bar 7674 is fixedly connected to the side of the support plate 7673 away from the rotating shaft 7671. A brush 7675 is fixedly connected to the outer surface of each support bar 7674. A support rod 7676 is fixedly connected between adjacent support bars 7674.

[0040] During the process of the camera 762 recognizing a human face, external dust impurities or artificial stroking may also cause impurities to adhere to it. Therefore, before the cover plate 766 rotates, the operator can drive the second rotating shaft 7671 to rotate by rotating the handle 7672, thereby driving the third support plate 7673, the support bar 7674, and the brush 7675 to rotate, so that the brush 7675 brushes the camera 762, causing the adhered dust to fall off the camera 762. After the cover plate 766 is opened, the dust on the brush 7675 will also automatically fall to the outside due to gravity.

[0041] The outer surface of the second rotating shaft 7671 is rotatably connected to the inner wall of the cover plate 766, and the outer surface of the brush 7675 is slidably connected to the outer surface of the camera 762.

[0042] The anti-counterfeiting unit includes a servo motor. The output end of the servo motor is fixedly connected to a reciprocating lead screw. A moving block is threadedly connected to the outer surface of the reciprocating lead screw. The top of the moving block is fixedly connected to a support column. One side of the support column away from the moving block is fixedly connected to a moving device. A guide rod is provided inside the moving device for directional control of movement. An eye-gaze collection device is slidably connected inside the moving device for detecting the eye focus of the person punching the card. The top of the moving device is fixedly connected to a hanging rod. The bottom of the hanging rod is fixedly connected to a support block. The outer surface of the support block is fixedly connected to a brush plate, and the brush plate can come into contact with the eye-gaze collection device to remove the dust adhering to the eye-gaze collection device.

[0043] After the camera 762 recognizes a human face, to prevent fraud using photos, videos, etc. for punching the card, the servo motor 81 will drive the reciprocating lead screw 82 to rotate, thereby driving the moving block 83 to move in front of the portrait. Then, the moving device 85 will start driving the eye-gaze collection device 87 to move along the guide rod 86. At the same time, the eye-gaze collection device 87 will also take a picture of the person's face and collect it and make eye contact with the person's eyes. If the person's eyes do not move following the movement of the eye-gaze collection device 87, the punching of the card will fail.

[0044] During the movement of the eye-gaze collection device 87, it will also come into contact with the brush plate 810 at the top. The brush plate 810 will remove the dust adhering to the eye-gaze collection device 87, avoiding the dust from hindering the eye-gaze collection device 87 from collecting the facial eye gaze.

[0045] The specific working process is as follows:

[0046] During operation, when the high-definition camera 761 captures the faces of employees, the micro-motor 764 drives the first rotating shaft 765 to rotate, thereby driving the shielding cover plate 766 away from the camera 762. Before the shielding cover plate 766 rotates, personnel can drive the second rotating shaft 7671 to rotate by rotating the handle 7672, thereby driving the third support plate 7673, the support bar 7674, and the brush 7675 to rotate, so that the brush 7675 brushes the camera 762, causing the adhered dust to fall off the camera 762. After the camera 762 recognizes the face, the servo motor 81 drives the reciprocating lead screw 82 to rotate, thereby driving the moving block 83 to move in front of the person's image. Then, the moving device 85 starts to drive the eye-gaze acquisition device 87 to move along the guide rod 86. At the same time, the eye-gaze acquisition device 87 also captures the person's face and makes eye contact with the person's eyes. If the person's eyes do not move following the movement of the eye-gaze acquisition device 87, the card punching will fail.

[0047] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention. Structures, devices, and operation methods not specifically described and explained in the present invention shall be implemented by conventional means in the art without special instructions and limitations.
