基于 Pyhton 的课堂人脸签到系统的设计与实现

摘要

本文基于当前大学生上课签到效率低下和代替上课现象普遍存在的问题，探

索一种利用人脸识别技术进行课堂签到的新方法。

本文旨在提高签到效率，防止代替上课现象的发生，并提升教学质量。本研

究采用 Python 的 OpenCV 与 Dilb 库实现对人脸的识别、记录和处理，使用 Flask

框架中的 jinja2 模板引擎进行动态的 HTML 页面搭建，通过 RESTful API 技术为

前后端提供数据交互。研究结果表明，基于人脸识别技术的课堂签到系统能够高

效、准确地识别学生的身份信息，有效预防代替上课现象，同时提高了教学效率

phenomenon of students skipping class, and enhance teaching quality.

The research uses OpenCV and Dilb libraries in Python to recognize, record, and

process facial information. The jinja2 template engine in Flask framework is used to

dynamically build HTML pages, and RESTful API technology is used for data

interaction between front-end and back-end. The results show that the attendance

system based on facial recognition technology can efficiently and accurately identify

students' identity information, effectively prevent the phenomenon of students skipping

class, and improve teaching efficiency and quality. This research provides a new idea

and technical route for solving the problem of classroom attendance among college

students, and has practical application and promotion value.
