Existing volumetric methods for predicting 3D human pose estimation are accurate, but computationally expensive and optimized for single time-step prediction. We present TEMPO, an efficient multi-view pose estimation model that learns a robust spatiotemporal representation, improving pose accuracy while also tracking and forecasting human pose. We significantly reduce computation compared to the state-of-the-art by recurrently computing per-person 2D pose features, fusing both spatial and temporal information into a single representation. In doing so, our model is able to use spatiotemporal context to predict more accurate human poses without sacrificing efficiency. We further use this representation to track human poses over time as well as predict future poses. Finally, we demonstrate that our model is able to generalize across datasets without scene-specific fine-tuning. TEMPO achieves 10$\%$ better MPJPE with a 33$\times$ improvement in FPS compared to TesseTrack on the challenging CMU Panoptic Studio dataset.

TEMPO是一种高效的多视角姿势估计模型，通过学习稳健的时空表示，提高了姿势准确性，同时还能跟踪和预测人体姿势。该模型通过循环计算个人的二维姿势特征，将空间和时间信息融合成一种表示，并利用时空上下文预测更准确的人体姿势，同时保持高效性。该模型能够跨数据集泛化而无需场景特定微调，达到了相比TesseTrack在具有挑战性的CMU Panoptic Studio数据集上MPJPE提升10%，帧率提升33倍的效果。
