基于手机相机的可见光成像通信实验系统设计
Design of Optical Camera Communication Experiment System Based on Camera of Mobile Phone
摘要
Abstract
In order to solve the problem that experiments of communication engineering professional course focus mainly on simulation,and practice are insufficient,a set of optical camera communication experimental system is designed.Using the host computer to edit information,the system employs a STM32 single-chip microcomputer to drive the high-frequency flicker of the strip-typed LED(Light Emitting Diode)illumination via an amplifying circuit,thus realizing the modulated transmission of information.And the mobile phone with a smart camera acts as a receiver to collect,demodulate and decode the strip information to get real-time information to display,which is implemented by a mobile application using Android Studio.The system integrates a variety of professional and practical technologies,such as embedded software,hardware development and Android development,to stimulate students'interest in learning.The experimental platform realizes coding,modulation,transmission,demodulation and decoding step by step,so that students can have a deep understanding of the principle of optical camera communication system through experiments,which is conducive to the study of professional education theory courses.关键词
