The invention provides a traffic vehicle multi-modal trajectory prediction system and method based on trajectory primitives, and the system comprises a similar trajectory screening module, a trajectory primitive library obtaining module, a primitive combination statistics module, a decoding prediction module, and a trajectory prediction network training module. The method comprises the steps of establishing a track primitive library of each scene, constructing and training a track prediction network corresponding to a primitive category, and performing multi-modal track prediction. According to the method, multi-modal trajectory prediction is carried out on the traffic vehicle from the perspective of trajectory elements for the first time, the interpretability of the trajectory prediction model is improved while it is guaranteed that the prediction result is multi-modal, meanwhile, the method only needs the historical trajectory of the traffic vehicle and does not need historical trajectories of vehicles around the traffic vehicle, and the prediction efficiency is improved. And the requirement of the trajectory prediction algorithm on the self-vehicle sensing range is reduced.

    本发明提供一种基于轨迹基元的交通车多模态轨迹预测系统及方法,系统包括相似轨迹筛选模块、轨迹基元库获取模块、基元组合统计模块、解码预测模块、轨迹预测网络训练模块,方法包括建立各个场景的轨迹基元库、对应基元类别的轨迹预测网络搭建与训练和多模态轨迹预测。本发明首次从轨迹基元的角度对交通车进行多模态轨迹预测,在保证预测结果多模态的同时,提高了轨迹预测模型的可解释性,同时该方法只需交通车的历史轨迹,无需交通车的周围车历史轨迹,降低了轨迹预测算法对自车感知范围的要求。
