Embodiment 1

[0024] The classroom sign-in method based on the distance threshold in this embodiment includes the following steps:

[0025] Step 1. Establish a teacher-student correspondence table according to the curriculum and upload it to the server for storage;

[0026] Step 2. Collect the student's facial information through the camera module and upload it to the server to generate identification information;

[0027] Step 3. The administrator obtains the student's leave information and uploads it to the server to generate a leave correspondence table;

[0028] Step 4. During the class, the teacher signs in according to the curriculum through the control terminal and retrieves the correspondence table and leave correspondence table in the server to determine the sign-in person who needs to sign in;

[0029] Step 5. The teacher sends the sign-in interface through the control terminal to display on the mobile terminal carried by the sign-in person, and at the same time obtains the dista...

Embodiment 2

[0035] On the basis of Embodiment 1, when the sign-in interface is locked, the countdown module displays the countdown to the sign-in deadline, and if the countdown expires, the sign-in fails. The countdown is displayed on the check-in interface through the countdown module to remind the check-in deadline and prevent the check-in from missing the check-in due to going to the toilet or going out temporarily.

Embodiment 3

[0037] On the basis of Embodiment 1, step 7 is also included. If the facial features do not match the identification information, the control terminal sends matching failure information to the corresponding mobile terminal, and the sign-in person needs to provide photo information again. To avoid that the control terminal cannot match the identification information when the photo information collected by the camera in the mobile terminal is not clear, resulting in failure to sign in.

Abstract

The invention discloses a classroom sign-in method based on distance thresholds. The method comprises the steps of: step 1, establishing a corresponding relationship table of teachers and students, and uploading the corresponding relationship table to a server for storage; step 2, collecting facial information of the student and uploading the same to the server to generate identification information; step 3, obtaining leave asking information of the students and uploading the same to the server to generate a leave asking corresponding table; step 4, performing, by a teacher, sign-in through acontrol terminal, and calling the corresponding relationship table and the leave asking corresponding table in the server to determine signers requiring sign-in; step 5, sending a sign-in interface toa mobile terminal for display, obtaining distance information D between the mobile terminal and the control terminal, when the distance is greater than a preset distance threshold A, defaulting, by the sign-in interface, sign-in failure; when the distance is less than a preset distance threshold C, popping up a camera to obtain current photo information of the singer and transmitting the currentphoto information to the control terminal; and then the distance is less than A and greater than C, locking the sign-in interface; and step 6, extracting facial features in the photo information, performing matching with the identification information, and indicating sign-in success in the case of matching.

Description

technical field [0001] The invention relates to the field of education management, in particular to a classroom sign-in method based on a distance threshold. Background technique [0002] Universities, specialized colleges, higher vocational technical colleges, and higher technical schools are collectively referred to as colleges and universities for short. In terms of academic qualifications and training levels, it includes junior college, undergraduate, master, and doctoral students. Universities are just one part of higher education.
