摘　　要：针对现有反针孔摄像装置的设备功能单一、识别精度较低、实时性较低等不足,设计了一套反针孔摄像装置实验系统。该系统采用四象限红外探测器,扩大了探测区域,基于自主划分的区域显示探测结果,通过STM32单片机将数据传输到配套APP,方便用户实地实时查看结果。同时利用ESP8266 WiFi模块攻击摄像头连接的网络,阻断数据传输,保证用户隐私安全。通过该实验,学生加深了对检测技术等相关理论的理解,熟悉利用单片机进行开发的流程,提高了解决实际问题的学习和实践能力。Aiming at the shortcomings of the existing anti-pinhole camera with single function, low recognition accuracy, and low real-time performance, an experimental system of anti-pinhole camera device was designed. The system uses a four-quadrant infrared detector to expand the detection area. Based on the autonomous division of the area, the detection results are transmitted to the supporting APP through STM32 microcontroller, which is convenient for users to view the results in real time. Meanwhile, the WiFi module of ESP8266 is used to attack the network connected to the camera to block data transmission and ensure privacy security of users. Through this experiment, students have a deep understanding of detection technology and other related theories, and are familiar with the development process using single chip microcomputer, so as to improve their learning and practical ability of solving practical problems.
