A class attendance image processing method based on face recognition

Abstract

The invention discloses a class attendance image processing method based on face recognition, comprising the following steps: a, capturing the original picture in the class; B, at least two cuts are made, the object of each cut is the original picture, and the positions of each cut to the original picture are different from each other; C, detecting and recognizing the face of the cut picture; D, matching the recognized face information with the pre-stored face information in the database; E, if the matching is successful, obtaining the identity information of the person corresponding to the human face information to sign in; This design divides the original picture into several parts, each part carries less face information, which is convenient for the system to recognize. At the same time, each cutting position must be different from each other to ensure that the face information on the original picture is retained completely in at least one part.

Description

technical field [0001] The invention relates to the field of classroom attendance, in particular to a classroom attendance image processing method for face recognition. Background technique [0002] There are many ways for students to check in in existing classrooms, such as manual check-in, clock-in, mobile phone check-in, etc., and even face recognition technology can be used. Before students enter the classroom, they stand in front of the camera and let the camera obtain face information. In the school database, each student will create a personal information file, which contains information such as the student's grade, class, course, etc., as well as the student's pre-stored face information. Face information matching, so as to obtain the student information corresponding to the face information, and sign in, but now we are facing a problem, it is impossible to set up too many cameras in the classroom, and the above sign-in procedure requires each student to stand at the...

Problems solved by technology

[0002] There are many ways for students to check in in existing classrooms, such as manual check-in, clock-in, mobile phone check-in, etc., and even face recognition technology can be used. Before students enter the classroom, they stand in front of the camera and let the camera obtain face information. In the school database, each student will create a personal information file, which contains information such as the student's grade, class, course, etc., as well as the student's pre-stored face information. Face information matching, so as to obtain the student information corresponding to the face information, and sign in, but now we are facing a problem, it is impossible to set up too many cameras in the classroom, and the above sign-in procedure requires each student to stand at the camera Face information in front of the face is inefficient. If the camera captures the image of the entire classroom, the image is too large and there are too many faces, the system cannot recognize it, and it is easy to cause confusion
