¿µ¹®³»¿ë¿ä¾à In traditional OCC systems, the transmit LED is detected by the camera receiver. However, in real-time applications such as V2X or robotics, there may be many LEDs that are not real transmitters. In this case, a higher probability of spurious data bits in the decoded data is expected, resulting in a higher BER. Moreover, processing the captured LED area along with other non-transmitting LED areas increases the complexity of the receiver. To intelligently deal with this problem, we propose a method combining SVM and CNN in the existing data decoding method for a stable OCC system.
