Abstract

Aiming at the current problem of difficult classroom attendance, the present invention provides a non-contact automatic classroom attendance device and method with strong real-time performance and high accuracy. The automatic classroom attendance device includes chips, devices, cameras and touch screens integrated on the ICETEK‑DM642‑C board. An attendance processing module is embedded in the FLASH chip, which includes: a face detection module, a face feature extraction module, a similarity measurement module, a face registration module, an attendance module, and a communication module. The attendance device and method have a high degree of automation, can greatly improve the efficiency and effect of classroom attendance, reduce the labor intensity of teachers, and improve the level of teaching management.

Description

technical field [0001] The invention relates to a high-recognition-rate automatic attendance device and method based on face recognition technology. Background technique [0002] In the daily study and life of universities and various colleges, classroom attendance is often a relatively important link. In the past, teachers often took some simple methods, such as roll call or asking students to submit registration slips. However, these relatively simple methods have the following two disadvantages. First, this method takes too long and may even affect the normal teaching time. Second, these methods may cause students to substitute answers or signs, so they are not Not a reliable method. Therefore, there is an urgent need for an automatic attendance checking method to replace manual attendance checking. [0003] At present, the attendance methods adopted by many companies and units mainly include: paper card punch clock, which records the attendance time through the attenda...
