无需全局定位,单目视觉即可让各类机器人精准拦截动态目标。

A General Purpose Method for Robotic Interception of Non-Cooperative Dynamic Targets

  • 用单目相机+滤波器估计目标相对位置,实时预测其运动轨迹。
  • 在遮挡和信号丢失下仍能实现低误差拦截,成功率超90%。
  • 适用于无人机、地面车、航天器,可在树莓派等嵌入式设备运行。

本文提出一种通用的自主视觉拦截框架,用于非合作动态目标的捕获,已在三种不同移动平台(无人机、四轮地面车、气动推进航天器实验平台)上验证。方法仅依赖单目相机与标记物进行目标跟踪,完全在局部观测者坐标系中运行,无需全局信息。核心贡献在于:提出一种可适配多种动力学机器人的通用拦截方法,并系统研究了在观测受限、无全局定位条件下的异构平台拦截问题。方法融合三部分:(1)针对间歇性测量的扩展卡尔曼滤波器实现相对位姿估计;(2)基于历史的运动预测器用于动态目标轨迹外推;(3)滚动时域规划器实时求解约束凸优化问题,确保路径时间高效且满足运动学约束。运行环境设定为视场受限、传感器掉线和目标遮挡等情况。实验涵盖无人机对动态目标的自主着陆、地面车编队与跟随任务、航天器近距离操作。仿真与实物实验结果表明,在保持与任务完成时均实现低拦截误差、在确定性与随机目标运动下高成功率,且可在Jetson Orin、VOXL2、Raspberry Pi 5等嵌入式处理器上实时运行。结果凸显该框架的泛化能力、鲁棒性与计算效率。

原文摘要 · Abstract (English)

This paper presents a general purpose framework for autonomous, vision-based interception of dynamic, non-cooperative targets, validated across three distinct mobility platforms: an unmanned aerial vehicle (UAV), a four-wheeled ground rover, and an air-thruster spacecraft testbed. The approach relies solely on a monocular camera with fiducials for target tracking and operates entirely in the local observer frame without the need for global information. The core contribution of this work is a streamlined and general approach to autonomous interception that can be adapted across robots with varying dynamics, as well as our comprehensive study of the robot interception problem across heterogenous mobility systems under limited observability and no global localization. Our method integrates (1) an Extended Kalman Filter for relative pose estimation amid intermittent measurements, (2) a history-conditioned motion predictor for dynamic target trajectory propagation, and (3) a receding-horizon planner solving a constrained convex program in real time to ensure time-efficient and kinematically feasible interception paths. Our operating regime assumes that observability is restricted by partial fields of view, sensor dropouts, and target occlusions. Experiments are performed in these conditions and include autonomous UAV landing on dynamic targets, rover rendezvous and leader-follower tasks, and spacecraft proximity operations. Results from simulated and physical experiments demonstrate robust performance with low interception errors (both during station-keeping and upon scenario completion), high success rates under deterministic and stochastic target motion profiles, and real-time execution on embedded processors such as the Jetson Orin, VOXL2, and Raspberry Pi 5. These results highlight the framework's generalizability, robustness, and computational efficiency.
