摘要:

本文提出了一种用于自动驾驶车辆的简单高效运动预测基线(SIMPL)。与传统的以智能体为中心的方法(精度高但计算重复)和以场景为中心的方法(精度和泛化性受损)不同,SIMPL 为所有相关交通参与者提供实时、准确的运动预测。为了在精度和推理速度上同时取得改进,我们提出了一种紧凑高效的全局特征融合模块,该模块以对称方式进行有向消息传递,使网络能够通过单次前向传播预测所有道路使用者的未来运动,并减轻由视角转换引起的精度损失。此外,我们研究了在轨迹解码中使用伯恩斯坦基多项式进行连续轨迹参数化,允许在任意所需时间点评估状态及其高阶导数,这对下游规划任务很有价值。作为一个强基线,SIMPL 在 Argoverse 1 和 Argoverse 2 运动预测基准上与其他最先进方法相比表现出极具竞争力的性能。此外,其轻量级设计和低推理延迟使 SIMPL 具有高度可扩展性,并有望用于实际车载部署。我们在 https://github.com/HKUST-Aerial-Robotics/SIMPL 开源了代码。

英文摘要:

This paper presents a Simple and effIcient Motion Prediction baseLine (SIMPL) for autonomous vehicles. Unlike conventional agent-centric methods with high accuracy but repetitive computations and scene-centric methods with compromised accuracy and generalizability, SIMPL delivers real-time, accurate motion predictions for all relevant traffic participants. To achieve improvements in both accuracy and inference speed, we propose a compact and efficient global feature fusion module that performs directed message passing in a symmetric manner, enabling the network to forecast future motion for all road users in a single feed-forward pass and mitigating accuracy loss caused by viewpoint shifting. Additionally, we investigate the continuous trajectory parameterization using Bernstein basis polynomials in trajectory decoding, allowing evaluations of states and their higher-order derivatives at any desired time point, which is valuable for downstream planning tasks. As a strong baseline, SIMPL exhibits highly competitive performance on Argoverse 1 & 2 motion forecasting benchmarks compared with other state-of-the-art methods. Furthermore, its lightweight design and low inference latency make SIMPL highly extensible and promising for real-world onboard deployment. We open-source the code at https://github.com/HKUST-Aerial-Robotics/SIMPL.
