摘要:
运动监控在长期康复中对脊髓损伤患者至关重要,其中多视角无标记运动捕捉方法已显示出显著潜力。然而,由于依赖校准和多视角同步的困难,其在患者自行部署环境中部署仍然具有挑战性。在本工作中,我们提出了一种基于代理的自同步多视角关节角度监控管道,利用两台摄像头在无标定环境中实现自动视频同步和代理驱动的自验证。最先进的单目2D姿态估计模型用于提取候选姿态,其中应用了基于代理的选择机制,以自动识别和跟踪目标个体,从而在多人和遮挡情况下产生一致的2D姿态。此类2D姿态被优化以从无标定的多视角姿态序列中估计关节角度,通过显式的几何建模确保可解释性。与Vicon系统的验证显示了该方法的强性能,达到MAE为5.97°±2.36°和Pearson相关系数为0.962±0.014。所提出的方法预计能提供一个实用的、患者可自行部署的系统,以在无标定的家庭环境中进行日常运动监控。
英文摘要:
Kinematic monitoring plays a critical role in long-term rehabilitation for patients with spinal cord injury (SCI), where multi-view markerless motion capture methods have shown significant potential. However, owing to the reliance on calibration and the difficulty of achieving multi-view synchronization, their deployment in patient self-deployed environments remains challenging. In this work, we propose an agentic pipeline for self-synchronized multi-view joint angle monitoring in uncalibrated environments using two cameras without hardware triggers. The Multimodal large language models enable automatic video synchronization and agent-driven self-verification. State-of-the-art monocular 2D pose estimation models are employed to extract candidate poses, where an agent-based selection mechanism is then applied to automatically identify and track the target subject, thereby producing consistent 2D poses in the presence of multiple individuals and occlusions. Such 2D poses are optimized to estimate joint angles from uncalibrated multi-view pose sequences, ensuring interpretability through explicit geometric modeling. Validation against Vicon system demonstrated the strong performance, achieving an MAE of $5.97^\circ \pm 2.36^\circ$ and a Pearson correlation coefficient of $0.962 \pm 0.014$. The proposed method is expected to provide a practical, patient self-deployable system to perform daily kinematic monitoring in uncalibrated home environments.
