Embodiment 2

[0203] The other methods are the same as those in Embodiment 1. In terms of communication, the wired network communication method can also be used. This method is suitable for the situation when the enterprise attendance and access control systems are relatively fixed.

Embodiment 3

[0205] For some enterprises without internal LAN, you can also only use the attendance function of the front desk. Some information of employees is stored in the embedded system. After the employee enters the employee ID number, the photo will be taken, and the input employee ID number, time and the photographed The face images of the employees are stored in the mobile storage unit, and the enterprise can copy the employee attendance information stored in the mobile storage unit to the computer for attendance attendance. Although this method does not perform face identification, the employee's image and Information such as ID number and attendance time are recorded on the record and can be confirmed afterwards, so it also has a very good attendance effect.

Abstract

A gate inhibition and work attendance device based on face discrimination technique are disclosed those include: cam used to read the face images, embedded system used to transmit the video information, input device used to input the identification information and computer used to distinguish the images and manage the work attendance. Said cam is connected with the embedded system, said embedded system is connected with the input device, and said embedded system is connected with the computer data. The gate inhibition and work attendance device also include mirror face used to confirm the side position of face, the cam is mounted on the top of mirror face, the optimal visual range of the cam is matched with the mirror face; said computer includes: image acquisition module, face image library, face detecting position module, image preprocessing module, face exercising module and face discrimination module. The invention provides the gate inhibition and work attendance device based on face discrimination technique with characterized that high discrimination success rate, easy to realize, high-speed to discriminate and judge, convenient to install and low implement cost.

Description

(1) Technical field [0001] The invention relates to an access control and time attendance device. (2) Background technology [0002] The enterprise's attendance management of employees and the placement of access control systems in important places have become an indispensable management method. At present, punch-card attendance or card-swipe attendance are commonly used. In card-swipe attendance, there are contact attendance machines and radio frequency card attendance machines. This type of attendance method , The phenomenon of checking in or swiping the card by other personnel happens from time to time, which affects the accuracy of attendance. In order to prevent the occurrence of the above phenomenon of attendance attendance, the phenomenon of modern punching often occurs, so people in the industry combined fingerprint identification technology to invent fingerprint attendance machine, combined with face identification technology to invent face recognition time attendan...
