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

Embodiment Construction

[0027] Such as figure 1 , figure 2 As shown, a class attendance image processing method based on face recognition includes the following steps:

[0028] a. Capture the original pictures in the classroom, where the camera captures the original pictures in the classroom at a fixed frequency;

[0029] b. Carry out at least two cuttings, the object of each cutting is the original picture, and the cutting position of the original picture is different each time;

[0030] c. Perform face detection and recognition on the cut picture;

[0031] d. Match the recognized face information with the pre-stored face information in the database;

[0032] e. If the matching is successful, the identity information of the person corresponding to the face information is obtained to sign in.

[0033] Before performing the above steps, it is necessary to prepare the database for pre-storage processing. Before step a, it also includes step z, entering the identity information and face information...

Abstract

The invention discloses a classroom attendance image processing method based on face recognition, comprising the following steps: a. capturing the original picture in the classroom; The positions of cutting the original picture are different from each other; c, face detection and recognition are carried out to the cut picture; d, matching the recognized face information with the pre-stored face information in the database; e, if the matching is successful, Then obtain the identity information of the person corresponding to the face information to sign in; this design divides the original picture into several parts, and the face information carried on each part will be relatively reduced, which is convenient for the system to identify. It is not the same, and the face information on the original picture is guaranteed to be completely preserved in at least one part.
