Abstract:

In order to meet diversified communication needs of the people and build a reliable low-cost communication link,we establish a novel display-to-camera communication system using display screen and photographic equipments in daily life.We build the system model and expound the transceiver's implementation framework,then design a colorful 2D code streaming consistent with the display screen properties for carrying information.Employ computer image processing technology to match,recognize and track the signal area,filter the background noise.Utilize frame classification and color enhancement technology to suppress the inter symbol interference.The system's data transfer rate is 287kbit/s and the decoding accuracy rate is 99.8%.

Key words: visible light communication, display-to-camera communication, system design, image processing
