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.
The face recognition attendance machine is mainly used for the attendance statistics of the company employees. When the employee signs in, the employee needs to collect the facial photos of the employees through the camera, and then obtain the feature values ​​from the collected photos through the face recognition algorithm and pre-stored with the database. The characteristic values ​​of the employee's face photos are analyzed and compared. After the identification is successful, the employee's name is reported, and the attendance is successful.
