摘要:
本文研究全景图像中的多目标跟踪(MOT),这带来了独特的挑战,包括360°视场(FoV)、分辨率稀释和严重的视图依赖畸变。为窄视场针孔相机设计的传统MOT方法在这些条件下泛化效果不佳。为了解决360° FoV下的全景畸变、大搜索空间和身份模糊问题,OmniTrack++采用了一个反馈驱动的框架,通过轨迹线索逐步优化感知。DynamicSSM模块首先稳定全景特征,隐式缓解几何畸变。在归一化表示的基础上,FlexiTrack Instances利用轨迹反馈进行灵活定位和可靠的短期关联。为确保长期鲁棒性,ExpertTrack Memory通过混合专家设计整合外观线索,能够从碎片化轨迹中恢复并减少身份漂移。最后,Tracklet Management模块根据场景动态在端到端和检测跟踪模式之间自适应切换,为全景MOT提供平衡且可扩展的解决方案。为支持严格评估,我们建立了EmboTrack基准,这是一个全景MOT综合数据集,包括用四足机器人捕获的QuadTrack和用双足轮腿机器人收集的BipTrack。这些数据集涵盖广角环境和多样的运动模式,为现实世界全景感知提供了具有挑战性的测试平台。在JRDB和EmboTrack上的大量实验表明,OmniTrack++实现了最先进的性能,与原始OmniTrack相比,在JRDB上HOTA提升+25.5%,在QuadTrack上提升+43.07%。数据集和代码将在https://github.com/xifen523/OmniTrack公开发布。
英文摘要:
This paper investigates Multi-Object Tracking (MOT) in panoramic imagery, which introduces unique challenges including a 360° Field of View (FoV), resolution dilution, and severe view-dependent distortions. Conventional MOT methods designed for narrow-FoV pinhole cameras generalize unsatisfactorily under these conditions. To address panoramic distortion, large search space, and identity ambiguity under a 360° FoV, OmniTrack++ adopts a feedback-driven framework that progressively refines perception with trajectory cues. A DynamicSSM block first stabilizes panoramic features, implicitly alleviating geometric distortion. On top of normalized representations, FlexiTrack Instances use trajectory-informed feedback for flexible localization and reliable short-term association. To ensure long-term robustness, an ExpertTrack Memory consolidates appearance cues via a Mixture-of-Experts design, enabling recovery from fragmented tracks and reducing identity drift. Finally, a Tracklet Management module adaptively switches between end-to-end and tracking-by-detection modes according to scene dynamics, offering a balanced and scalable solution for panoramic MOT. To support rigorous evaluation, we establish the EmboTrack benchmark, a comprehensive dataset for panoramic MOT that includes QuadTrack, captured with a quadruped robot, and BipTrack, collected with a bipedal wheel-legged robot. Together, these datasets span wide-angle environments and diverse motion patterns, providing a challenging testbed for real-world panoramic perception. Extensive experiments on JRDB and EmboTrack demonstrate that OmniTrack++ achieves state-of-the-art performance, yielding substantial HOTA improvements of +25.5% on JRDB and +43.07% on QuadTrack over the original OmniTrack. Datasets and code will be made publicly available at https://github.com/xifen523/OmniTrack.
