- 适合部署在机器人、无人车等移动平台进行全天候监控
无人机快速普及带来安全与隐私挑战,亟需高效检测技术。传统帧相机在高速目标或恶劣光照下性能受限。事件相机基于生物视觉原理,具备高动态范围和微秒级响应,更适合无人机探测。但现有方法多假设相机静止,难以应用于移动载体。本文提出一种面向移动平台的实时无人机检测系统,采用旋转事件相机实现360°水平视场,并可估计目标方位。创新性地提出无需运动补偿的类图像事件表示,结合轻量级神经网络实现高效时空学习。系统部署于Jetson Orin NX上,实测在户外复杂条件下平均角度误差低于2°,验证了其在真实场景中的可靠性。代码将开源以支持后续研究。
原文摘要 · Abstract (English)
The rapid proliferation of drones requires balancing innovation with regulation. To address security and privacy concerns, techniques for drone detection have attracted significant attention.Passive solutions, such as frame camera-based systems, offer versatility and energy efficiency under typical conditions but are fundamentally constrained by their operational principles in scenarios involving fast-moving targets or adverse illumination.Inspired by biological vision, event cameras asynchronously detect per-pixel brightness changes, offering high dynamic range and microsecond-level responsiveness that make them uniquely suited for drone detection in conditions beyond the reach of conventional frame-based cameras.However, the design of most existing event-based solutions assumes a static camera, greatly limiting their applicability to moving carriers--such as quadrupedal robots or unmanned ground vehicles--during field operations.In this paper, we introduce a real-time drone detection system designed for deployment on moving carriers. The system utilizes a spinning event-based camera, providing a 360° horizontal field of view and enabling bearing estimation of detected drones. A key contribution is a novel image-like event representation that operates without motion compensation, coupled with a lightweight neural network architecture for efficient spatiotemporal learning. Implemented on an onboard Jetson Orin NX, the system can operate in real time. Outdoor experimental results validate reliable detection with a mean angular error below 2° under challenging conditions, underscoring its suitability for real-world surveillance applications. We will open-source our complete pipeline to support future research.
