摘要:

对周围车辆的运动预测是自动驾驶车辆处理的最重要的任务之一,也是自动驾驶系统中确保所有相关交通参与者安全所必需的关键步骤。最近,来自学术界和工业界的许多研究人员都关注这一重要问题,提出了从基于规则的工程方法到学习方法的各种想法,这些想法在不同的预测范围内表现良好。特别是,虽然对于长期轨迹,工程方法优于竞争方法,但学习方法已被证明是短期的最佳选择。在这项工作中,我们描述了如何克服这两个研究方向之间的差异,并提出了一种方法,在一个统一的框架下结合不同的方法。由此产生的算法融合学习,不确定性感知轨迹与基于车道的路径在原则上的方式,从而提高预测精度在短期和长期的视野。对真实世界的大规模数据的实验强烈表明了所提出的统一方法的优点,其性能优于现有的最先进的方法。此外,在离线评估之后,所提出的方法在自动驾驶车辆上成功地进行了测试。

英文摘要:

Motion prediction of surrounding vehicles is one of the most important tasks handled by a self-driving vehicle, and represents a critical step in the autonomous system necessary to ensure safety for all the involved traffic actors. Recently a number of researchers from both academic and industrial communities have focused on this important problem, proposing ideas ranging from engineered, rule-based methods to learned approaches, shown to perform well at different prediction horizons. In particular, while for longer-term trajectories the engineered methods outperform the competing approaches, the learned methods have proven to be the best choice at short-term horizons. In this work we describe how to overcome the discrepancy between these two research directions, and propose a method that combines the disparate approaches under a single unifying framework. The resulting algorithm fuses learned, uncertainty-aware trajectories with lane-based paths in a principled manner, resulting in improved prediction accuracy at both shorter- and longer-term horizons. Experiments on real-world, large-scale data strongly suggest benefits of the proposed unified method, which outperformed the existing state-of-the-art. Moreover, following offline evaluation the proposed method was successfully tested onboard a self-driving vehicle.
