“…OWC, which uses image sensors or cameras, is a promising technology due to LoS functionalities combined with LED illumination, and image sensor-based OWC techniques have several advantages over existing wireless communication technologies, such as communication using single-element PDs and radio waves. 11,12,28 Image sensors can build image pixels projected from various light sources within its FoV. Figure 1 illustrates the characteristics of an image sensor in a vehicular environment.…”

In this article, we introduce an image sensor-based optical vehicular communication system for performing vehicular condition resolution adaptively in the spatial domain and the temporal domain. To validate the proposed system, a dual camera-based approach is presented here, where a vision camera is used to detect multiple vehicles of interest (i.e. spatial condition), a communication link is set up, and then, a high-speed camera adapts its resolution to ensure fast processing and high-rate data communication (i.e. temporal condition). We suggest an adaptive algorithm that supports the detection of and communication multiple vehicles simultaneously in spatial-temporal condition. Moreover, we propose a combination of scale-invariant feature transform and iterative closest point for detection and classification of multiple vehicles. To prove the feasibility of our proposed scheme, we present simulation results.

“…As shown in Fig. 1, data transmitted from LED traffic lights, signage, pavement markers, headlights, and tail lights can be received using the image sensor [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] . An LED traffic light transmits safety information to cars.…”

“…We also note that the SNR (Signal-to-Noise Ratio) is rather high even in outdoors [14] . Another interesting feature of image sensors is that the stable SNR is confirmed as long as the projected image of the LED transmitter occupies several pixels [19] . In other words, the received SNR remains stable for a certain communication distance.…”

This paper introduces infrastructure-to-vehicle and vehicle-to-vehicle communications using VLC. A VLC coupled with a high-speed image sensor is introduced (i.e., image sensor communication). The high-speed image sensors provide eyes for autonomous and connected vehicles. VLC imparts data reception capability to image sensors with necessary functions, which can then be provided to autonomous and connected vehicles. In this paper, some of our research on coupling VLC to high-speed image sensors is introduced, including our key findings: the basics of ISC, a vehicle motion model, and range estimation.
