  • 结合深度信息与轨迹匹配算法,打通视觉与射频数据
  • 在遮挡和离线时仍可实现厘米级定位精度
  • 首次在自然林地场景应用双模态融合追踪

被动式RFID标签为大规模资产追踪提供了一种低成本、可扩展的解决方案。然而,在林地环境中,信号衰减和多径效应通常使RFID的空间精度限制在米级。相比之下,采用立体视觉的摄像头可达到厘米级精度,但仅依赖计算机视觉在密集场景下难以解决空间关联模糊和部分遮挡问题。融合两种模态可同时利用视觉的高精度与RFID的非视距识别优势。本文核心挑战在于准确关联两个传感器产生的异构轨迹。为此,我们提出一种新型摄像头-RFID融合框架,结合深度信息与物体特征,并引入先进的轨迹匹配算法。该方法成功弥合了米级到厘米级的精度差距,在资产短暂离开摄像头视野时仍能实现可靠标签定位。据我们所知,这是首个将摄像头-RFID融合应用于自然林地环境资产追踪的工作。

原文摘要 · Abstract (English)

Passive RFID tags offer a cost-effective and scalable solution for tracking numerous deployed assets. However, in forested environments, signal attenuation and multipath effects generally limit RFID spatial accuracy to the meter level. Conversely, while cameras employing stereo vision can achieve centimeter-level precision, relying solely on computer vision fails to resolve issues arising from spatial association ambiguity and partial occlusions in dense settings. Fusing these modalities allows systems to harness the high-accuracy benefits of vision while retaining the robust, non-line-of-sight identification advantages of RFID. Yet, a primary challenge in achieving this, which is the central focus of this paper, lies in accurately associating the disparate trajectories generated by these two sensors. To overcome this limitation, we introduce a novel camera--RFID fusion framework that integrates depth and object information with advanced trajectory-matching algorithms. By successfully bridging the meter-to-centimeter accuracy gap, the proposed approach helps achieve reliable tag localization even when assets temporarily leave the camera's field of view. To the best of our knowledge, this represents the first application of camera--RFID fusion for asset tracking in natural forested environments.
