[0002] With the continuous advancement of science and technology, face recognition technology has been widely used in many fields, such as access control systems, attendance management, security monitoring, etc. However, traditional face recognition systems mostly rely on monocular cameras, and their recognition performance is limited under complex lighting conditions and changing backgrounds. Due to the lack of depth information, monocular cameras are easily affected by lighting changes, occlusions, and changes in facial angles, making it impossible for the personnel recognition function to extract the characteristic information of the person well, resulting in recognition errors or failures, and unable to perform effective personnel recognition, which affects work efficiency. In addition, the existing system also has shortcomings in user experience and management convenience. The operation process is complicated, the user interaction is not friendly enough, and the management of visitors is not perfect, affecting the overall safety and efficiency. Therefore, we propose a face recognition access control system device based on intelligent digital registration. Summary of the invention

[0003] The purpose of the present invention is to provide a face recognition access control system device based on intelligent digital registration. The system uses binocular cameras to perform face recognition. Through the principle of stereoscopic vision, it can accurately identify the position and angle of the face under various lighting conditions and complex backgrounds. Compared with monocular cameras, binocular cameras have higher adaptability and stability, which solves the problem that traditional face recognition systems rely heavily on monocular cameras, and their recognition performance is limited under complex lighting conditions and changing backgrounds. Due to the lack of depth information, monocular cameras are easily affected by changes in lighting, obstructions and changes in facial angles, making it impossible for the personnel recognition function to extract the characteristic information of the person well.

[0026] A specific application of this embodiment is: first, the face image of the person entering the control area is collected by a binocular camera. The binocular camera uses the principle of stereoscopic vision to achieve accurate positioning and angle recognition of the face, thereby significantly improving the accuracy of face recognition. Then, the face recognition module preprocesses the collected face image, including denoising, brightness adjustment and contrast enhancement. These operations help to further optimize the image quality and provide more reliable data for subsequent feature extraction. The feature extraction module extracts key features from the preprocessed face image and records these feature vectors. The data analysis module then compares these extracted feature vectors with the facial features of registered employees in the database to determine whether the person is a registered employee. If the comparison is successful, the communication module transmits this information to the PLC controller. The PLC controller controls the roller gate to open according to the received signal to allow the person to enter the control area. The warning light remains off, indicating that there is no security threat. However, If the data analysis module finds that the person is not a registered employee, it will send different signals to the PLC controller, which will then control the roller gate to remain closed to prevent unauthorized entry and trigger the warning light to flash in eye-catching colors to alert people around to potential safety risks. The different colors and flashing modes of the warning light can quickly convey key information and enhance the safety warning effect. The interactive interface allows administrators to interact with the system in a user-friendly way. Administrators can view entry and exit records and manage user accounts through the interactive interface. The classification query function can help administrators quickly filter and find data under specific conditions, such as visitor records within a specific time period or access to a specific area. These functions enable administrators to manage the system more efficiently, improve security and management efficiency. Finally, all collected data, including employee and visitor information, will be stored in the cloud by the storage module. In this way, when security issues arise, administrators can easily track user behavior and discover abnormal activities.
