This paper presents a demonstration of an short-range optical camera communication(OCC) system for vehicle-to-vehicle(V2V) text message exchange. The transmitter uses an array of low-power infrared(IR) light-emitting diodes(LEDs) to transmit text messages. The lighting patterns in the transmitter LED array vary with different characters, which are detected as different images at the receiver. The receiver is a commercial complementary metal oxide semiconductor(CMOS)-based USB web camera. The USB web camera receives the pattern of the transmitter LEDs and the received images are processed in PC to recover original text messages. The decoding process is implemented using OpenCV with Python. According to the experiment results, the data can be retrieved with 1.6 % frame error rate in a range up to 5 m at a data rate of 10 characters per second.
