Teaching attendance method based on human face recognition

Abstract

The invention provides a teaching attendance method based on human face recognition, and relates to the technical field of electronics. The method comprises the steps that the curriculum schedule of each classroom is preset, and the human face images of students corresponding to each curriculum schedule are collected in advance to extract feature points to acquire feature samples; a camera device automatically starts at the beginning of each class; the camera device takes a picture and transmits the picture to a background server through a network; the background server carries out human face detection on the taken picture; the number of different detected human face images is counted; different human face images are extracted, and the identities of the students are retrieved through a human face recognition algorithm; the curriculum schedule information generated when attendance images are collected is recorded; attendance information is generated according to the identities of the students and sent to an attendance management terminal. According to the invention, classroom teaching time can be saved, and attendance substitution can be avoided.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a face recognition-based teaching attendance method. Background technique [0002] At present, the methods used in campus classroom attendance include manual roll-calling according to the roster and attendance machine check-in roll-calling. Among these methods, the manual roll call of the roster is not only inefficient in roll call and statistics, but also takes up a lot of precious class time; the attendance machine punches the roll and only recognizes the card but does not recognize the person, and the favored punching and replacing the punching card is serious, and basically loses the possibility of attendance. significance. At the same time, when checking attendance on the attendance machine, students need to go to the machine at the attendance point to complete the attendance in a short period of time before and between classes. Queues and congestion frequently occur, c...

Problems solved by technology

Among these methods, the manual roll call of the roster is not only inefficient in roll call and statistics, but also takes up a lot of precious class time; the attendance machine punches the roll and only recognizes the card but does not recognize the person, and the favored punching and replacing the punching card is serious, and basically loses the possibility of attendance. significance

At the same time, when checking attendance on the attendance machine, students need to go to the machine at the attendance point to complete the attendance in a short period of time before and between classes. Queues and congestion frequently occur, causing chaos on the spot, delaying class time, affecting efficiency, and even once appeared A large number of attendance settings and construction investment are idle and abandoned after construction, resulting in a waste of school investment
