本研究的重点是用于图像传感器通信（ISC）的旋转LED发射器（RLT）。RLT是一种利用led闪烁时移动产生的后像来提高传输速率的设备。在真实环境中使用RLT时，接收机需要在数据解调前检测到采集图像上的发射器位置和灯光后像。提出了一种利用RLT检测ISC残像位置和残像坐标的方法。实验结果表明，该方法在较短的距离范围内没有误检。
This study focuses on a rotary LED transmitter (RLT) for image sensor communication (ISC). RLT is a device that improves the transmission rate by utilizing the afterimages generated by moving the LEDs while blinking. When RLT is used in a real environment, the receiver needs to detect the position of the transmitter and the afterimages of lights on the captured image before data demodulation. This paper proposes a method for detecting the position of RLT and the coordinates of afterimages for ISC using RLT. Experimental results show that the proposed method operates correctly without false detection of them in the range of short distances.
