摘要:

预测道路车辆的未来轨迹对于自动驾驶至关重要。在本文中,我们介绍了一种新的预测框架,称为PRIME,它代表基于模型的规划预测。与利用神经网络对场景上下文进行建模并产生无约束轨迹的最近预测工作不同,PRIME旨在生成准确且可行性有保证的未来轨迹预测。PRIME通过利用基于模型的生成器在显式约束下生成未来轨迹来保证轨迹的可行性,并通过利用基于学习的评估器选择未来轨迹来实现准确的多模态预测。我们进行实验的大规模Argoverse运动预测基准,其中PRIME优于国家的最先进的方法在预测精度,可行性和鲁棒性下不完美的跟踪。

英文摘要:

Predicting the future trajectories of on-road vehicles is critical for autonomous driving. In this paper, we introduce a novel prediction framework called PRIME, which stands for Prediction with Model-based Planning. Unlike recent prediction works that utilize neural networks to model scene context and produce unconstrained trajectories, PRIME is designed to generate accurate and feasibility-guaranteed future trajectory predictions. PRIME guarantees the trajectory feasibility by exploiting a model-based generator to produce future trajectories under explicit constraints and enables accurate multimodal prediction by utilizing a learning-based evaluator to select future trajectories. We conduct experiments on the large-scale Argoverse Motion Forecasting Benchmark, where PRIME outperforms the state-of-the-art methods in prediction accuracy, feasibility, and robustness under imperfect tracking.
