The face recognition attendance machine is a new type of storage attendance machine. It only needs to collect the employee's face image and establish the file in advance. When the employee goes to work in the recognition area of ​​the face recognition attendance machine, the attendance machine will be fast. Record attendance status and save records.
The face recognition attendance machine adopts the high-precision technology of today's international technology field-face recognition technology (incorporating the computer image processing technology and the principle of biostatistics), and uses computer image processing technology to extract portrait feature points from video. The principle of biostatistics is analyzed and a facial feature template is created. When the registered person walks in front of the face recognition machine, it will have a voice prompt "Hello" or the name of the person indicating that the attendance has been successful. Moreover, it also has an image update function. If the image being taken is taken as the first face, the second face is stored, and if the first face image is consistent with the second face image, the face recognition attendance machine The first face image will be automatically saved to update the second face image. The method can maintain the update of the user's face image, reduce the influence of the face shape change on the recognition, and increase the accuracy of the recognition.
1. The method of positioning the key area of ​​the face is high in accuracy and safety.
2. The special dual camera is generally adopted, which belongs to the quasi-three-dimensional face recognition technology. The recognition performance greatly exceeds the two-dimensional face recognition, and the algorithm complexity is much lower than the three-dimensional face recognition.
3. Recognition performance is not affected by ambient light, and reliability is good.
4. You can upload the user name list and download the access control attendance record and photos through the USB flash drive.
5. The device status can be set through the TCP/IP network, and the download information can be uploaded; the network communication data is encrypted.
6. Naturalness, the recognition method is the same as the biological characteristics used by humans for individual identification.
7. Completely non-contact, avoiding bacterial infections and making them healthier and healthier.
8. Voice prompt, whether the real voice utters the face image is verified successfully.
9. Can be used independently, without the need to connect to a computer, you can complete the functions of personnel registration, face attendance, storage records and so on.
What is the principle of identifying the attendance machine? For many users who want to understand the face recognition attendance machine, the working principle of this seemingly tall face attendance machine is undoubtedly clear. Face recognition technology is not novel, and has been applied in many fields. The face recognition attendance machine is an example. This biometric recognition technology is one of the important directions for the future development of smart locks.
The face recognition attendance machine is a new access control management attendance system that integrates regional feature analysis algorithm, computer image processing technology and biostatistics principle. The workflow is not complicated.
1. The face information is captured by the camera, stored as the original control parameter, the portrait feature points are extracted, the mathematical model is established and the mathematical model is established, and the portrait feature template is established.
2. Detecting the attendance personnel facing the camera, the face recognition attendance machine will extract the face information and match the template stored in the computer. The feature points can be judged to be the same person when they reach a certain proportion.
3. If the judgment result is successful, the attendance is completed, and if the judgment result fails, the attendance record cannot be completed.
To put it simply, the face recognition attendance machine is a storage class attendance machine, which establishes files, analyzes and recognizes the completion of attendance, and mainly compares face features.
The face recognition attendance machine uses the face being detected as the first face, and the original portrait data entered as the second face, and if the two face image informations match, the recognition passes.
The new face recognition attendance machine has an automatic update function. The first face that recognizes success will replace the second face. The result will be more accurate. The face features may change with factors such as time age or makeup color, and the update is automatically updated. The function undoubtedly greatly improves the recognition accuracy.
