摘要
对周围车辆轨迹的精确预测可以辅助自动驾驶车辆做出合理的即时决策。虽然相比传统轨迹预测算法,深度学习方法已取得较好效果,但是自动驾驶车辆在异构高动态复杂变化环境下实现多模态高精度预测仍存在信息丢失、交互和不确定性难以建模、预测缺乏可解释性等问题。Transformer具备的长距离建模能力和并行计算能力使其不仅在自然语言处理领域取得巨大成功,而且在扩展至自动驾驶多模态轨迹预测任务时也解决了以上问题。基于此,对过去基于深度神经网络的方法,特别是对基于Transformer的方法进行全面总结与回顾;同时分析了Transformer相较于传统序列网络、图神经网络、生成模型的优势,并结合现有难题进行针对性分析与分类。Transformer模型可以更好地应用于多模态轨迹预测任务,此类模型具有更好的泛化性和可解释性。最后,对多模态轨迹预测未来发展方向进行了展望。
Although deep learning methods have achieved better results than traditional trajectory prediction algorithms,there are still problems such as information loss,interaction and uncertainty difficulties in modelling,and lack of interpretability of predictions when implementing multimodal high-precision prediction for autonomous vehicles in heterogeneous,highly dynamic and complex changing environments.The newly developed Transformer's long-range modelling capability and parallel computing ability make it a great success not only in the field of natural language processing,but also in solving the above problems when extended to the task of multimodal trajectory prediction for autonomous driving.Based on this,the aim of this paper is to provide a comprehensive summary and review of past deep neural network-based approaches,in particular the Transformer-based approach.The advantages of Transformer over traditional sequential network,graphical neural network and generative model were also analyzed and classified in relation to existing challenges,simultaneously.Transformer models can be better applied to multimodal trajectory prediction tasks,and that such models have better generalisation and interpretability.Finally,the future directions of multimodal trajectory prediction were presented.
