An infrared image attendance method based on large field of view binocular vision

Abstract

The invention discloses a large field of view binocular vision infrared image attendance method. The method uses binocular infrared cameras at both ends of the wall where the classroom blackboard is located to collect data on student images, and then stitches the two images of the left eye and the right eye. Synthesize large-format and large-view images in the classroom, then automatically locate the face area in the image, complete the determination of student identity through feature extraction, recognition comparison, etc., and finally realize the attendance of students. Traditional attendance methods based on visible light images are easily affected by factors such as illumination changes and complex backgrounds, resulting in low recognition rates. This method effectively overcomes this problem, and can also accurately record and count the situations of students being late, leaving early, and absenteeism, which improves the work efficiency of classroom attendance, saves time and resources for teachers, reduces the burden on teachers, and improves Improve the school's teaching quality and promote the construction of the school's school spirit and style of study.

Description

technical field [0001] The invention relates to face recognition technology, in particular to an infrared image attendance method with large field of view and binocular vision. Background technique [0002] In colleges and universities, the student's class attendance rate is the main basis for the teacher to give the usual grades. At present, most colleges and universities in our country still mainly use manual attendance check or smart card attendance check in the daily attendance work of students. Although these attendance methods can play a certain role, the existing problems are also very prominent. Teachers do not know every student, and manual attendance and smart card attendance may have impostors and substitute attendance. Therefore, the traditional roll call attendance method is not suitable for the school's attendance needs. Therefore, designing a classroom attendance system that can solve the above problems is of great significance for facilitating teachers' cla...

Problems solved by technology

However, this method has insurmountable defects, especially when the ambient light changes, the recognition effect will drop sharply, which cannot meet the needs of the actual system
