光学相干断层扫描因其高空间分辨率和固有的深度感知能力，是一种有前景的无标记运动跟踪模态。然而，现有的基于OCT的跟踪方法在可跟踪速度方面受到限制，特别是在顺序跟踪多个路标以进行6D姿态估计时。在这项工作中，我们提出了一种预测性跟踪方法，该方法在多个被跟踪的路标之间传播位置更新，以获得全局姿态预测。这使得在高速度下实现更鲁棒的跟踪成为可能。我们的结果表明，在速度高达100 mm/s且连续跟踪多达九个路标的情况下，均方根误差（RMSE）低于1 mm，凸显了全局运动传播与预测在提高基于OCT的跟踪鲁棒性方面的潜力。
英文摘要
Optical coherence tomography is a promising modality for markerless motion tracking due to its high spatial resolution and inherent depth perception. However, existing OCT-based tracking approaches are limited in terms of trackable velocity, particularly when multiple landmarks are tracked sequentially for 6D pose estimation. In this work, we present a predictive tracking approach that propagates positional updates between multiple tracked landmarks to obtain a global pose prediction. This enables more robust tracking under high velocities. Our results demonstrate RMSEs below 1 mm for velocities up to 100 mm/s and up to nine consecutively tracked landmarks, highlighting the potential of global motion propagation and prediction for improving the robustness of OCT-based tracking.
