RF频谱可用性和易受干扰性的固有限制使得其难以满足汽车安全应用所需的可靠性。为了应对这一挑战，这项工作探索了一种称为Visual MIMO的替代通信系统，该系统使用发光阵列作为发射器，使用摄像头作为接收器。应用于车辆通信的视觉MIMO提出将现有的LED尾灯和前灯重新用作发射器，将现有的摄像头（例如用于停车辅助的摄像头、后视摄像头）重新用作接收器。在这项工作中，我们展示了一个基于演示的视觉MIMO系统的概念证明，该系统由一个LED发射器阵列和一个高速摄像机组成。
The inherent limitations in RF spectrum availability and susceptibility to interference make it difficult to meet the reliability required for automotive safety applications. To address this challenge, this work explores an alternative communication system called Visual MIMO that uses light emitting arrays as transmitters and cameras as receivers. Visual MIMO applied to vehicular communication proposes to reuse existing LED rear and headlights as transmitters and existing cameras (e.g. those used for parking assistance, rear-view cameras) as receivers. In this work we show a proof of concept based demonstration of the Visual MIMO system consisting of an LED transmitter array and a high-speed camera.
