论文摘要
3D多对象跟踪（MOT）是自动驾驶汽车的关键问题，即在动态环境中执行灵活的运动计划所需的。特别是对于密集的占领场景，将现有曲目与新检测相关联仍然具有挑战性，因为现有系统倾向于省略关键的上下文信息。我们提出的解决方案InterTrack引入了3D MOT的相互作用变压器，以生成数据关联的区分对象表示。我们为每个轨道和检测提取状态和形状特征，并通过注意力有效地汇总全局信息。然后，我们对每个轨道/检测功能对进行学习的回归以估计亲和力，并使用强大的两阶段数据关联和轨道管理方法来生成最终轨道。我们在Nuscenes 3D MOT基准上验证了我们的方法，在那里我们观察到了显着的改进，尤其是在物理大小和聚类对象的类别上。从提交开始时，使用CenterPoint检测的方法中，InterTrack在总体AMOTA中排名第一。
3D multi-object tracking (MOT) is a key problem for autonomous vehicles, required to perform well-informed motion planning in dynamic environments. Particularly for densely occupied scenes, associating existing tracks to new detections remains challenging as existing systems tend to omit critical contextual information. Our proposed solution, InterTrack, introduces the Interaction Transformer for 3D MOT to generate discriminative object representations for data association. We extract state and shape features for each track and detection, and efficiently aggregate global information via attention. We then perform a learned regression on each track/detection feature pair to estimate affinities, and use a robust two-stage data association and track management approach to produce the final tracks. We validate our approach on the nuScenes 3D MOT benchmark, where we observe significant improvements, particularly on classes with small physical sizes and clustered objects. As of submission, InterTrack ranks 1st in overall AMOTA among methods using CenterPoint detections.
