光学相机通信（OCC）是无人机与地面相机之间进行远距离点对多点通信的一种有前途的解决方案。OCC要求摄像机具有视距（LoS）通道，以接收从安装在无人机上的LED灯或面板传输的光学信号。当多个无人机部署在某个区域以同时传输光信号时，避免光间干扰是一个重要问题。光间干涉在以前的工作中已经建模。然而，现有的工作还没有充分研究无人机的轨迹控制。为了解决这个问题，在本文中，我们提出了一种分布式的无人机轨迹控制算法，以避免光间干扰。基于图像平面中的近似干扰模型，每个无人机控制其轨迹，以确保其他无人机的LoS通信链路。所提出的算法的性能通过激烈的多智能体仿真确认。该算法有助于在无人机和地面摄像机之间建立稳定的点对多点OCC链路。
Optical Camera Communication (OCC) is a promising solution for long-range point-to-multipoint communication between drones and a ground camera. OCC requires line-of-sight (LoS) channels for a camera to receive optical signals transmitted from drone-mounted LED lights or panels. When multiple drones are deployed in a certain area to transmit optical signals simultaneously, inter-light interference avoidance is a significant issue. The inter-light interference has been modeled in the previous works. However, existing works have not sufficiently investigated the trajectory control of drones. To address this issue, in this paper, we propose a distributed trajectory control algorithm for drones to avoid inter-light interference. Based on the approximate interference model in the image plane, each drone controls its trajectory to ensure LoS communication links of other drones. The performance of the proposed algorithm is confirmed via intense multi-agent simulation. The proposed algorithm contributes to establishing stable point-to-multipoint OCC links between drones and a ground camera.
