Example Embodiment

[0014] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0015] Such as figure 1 The illustrated embodiment is a full-process automatic attendance system used in classrooms, which is applied in university classrooms. The attendance system includes four main sub-systems: pre-stored data acquisition system, acquisition system, analysis system and statistical system. The pre-stored data acquisition system uses a 13-megapixel high-definition camera to collect three images of the front, left and right sides of the attendant's face, and store the images as standard data and pass them to the analysis system. The acquisition system includes 4 CCD cameras, which are respectively set in the upper left corner, upper right corner of the front of the classroom, and above the left and right walls of the classroom. The camera parameters such as focal length, height, and elevation angle of the camera are calibrated to ensure that ...

Abstract

The invention discloses a whole-process automatic attendance system used in a classroom. The whole-process automatic attendance system comprises a collecting system, an analyzing system and a statistical system, wherein the collecting system comprises cameras; four cameras are arranged in total and are respectively arranged at left upper corner and right upper corner on the front side of the classroom, above the left wall of the classroom and above the right wall of the classroom; the analyzing system comprises a database, in which the face standard data of attendance people are stored in advance, and is used for comparing the real-time images collected by the cameras with the pre-stored data in the database and then sending a comparison result to the statistical system; the statistical system is used for generating a report for the attendance people according to the comparison result. The invention has the beneficial effects that the accuracy is higher and the whole-process attendance recording for people in the classroom can be accurately performed.

Description

technical field [0001] The invention belongs to the field of network information collection and control, in particular to a whole-process automatic attendance system used in classrooms. Background technique [0002] The application of classroom attendance assessment generally includes two situations: class attendance and examination attendance. Taking university classrooms as an example, in the class scene, traditional methods such as "roll call", "swipe card", "fingerprint" and "semi-manual intervention attendance" cannot effectively solve the problem of "replacing attendance" and "attendance first, then attendance later". slip away" etc. In the examination scene, if you encounter major examinations such as "civil service examination", "professional title examination", "secondary and college entrance examinations", and "CET-4 and CET-6", the invigilator is not familiar with the examiners and can only compare them with the naked eye The picture of the certificate held by t...
