Large-visual-field binocular vision infrared imagery checking method

Abstract

The invention discloses a large-visual-field binocular vision infrared imagery checking method. The method comprises the following steps: collecting data of student images by utilizing the binocular infrared cameras at two ends of a wall on which a blackboard is located in a classroom; splicing left and right two images; compounding into a large-frame large viewing angle image in the classroom; automatically positioning human face area part in the image; confirming the identity of the students by performing the processes of feature extraction and recognition comparison, thereby lastly realizing the check on the attendance of the students. The traditional checking method based on visible light image is easily influenced by the factors of illumination variation and complex background so that the recognition rate is low. The method provided by the invention can effectively solve the problem; according to the method, the conditions of being late, early leaving and absenteeism of the students can be accurately recorded and counted; the working efficiency of classroom checking is increased; the time resource of the teachers is saved; the burden of the teachers is relieved; the teaching quality of the school is increased; the school spirit and study style construction of the school is promoted.

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
