The invention discloses a vehicle trajectory prediction method based on time-space fusion attention. The method comprises a data preprocessing module DPM, a data preprocessing module DPM, a time feature extraction module TEM, a spatial feature extraction module SEM and a trajectory prediction module TPM. According to the method, the dynamic undirected graph is used for representation, the vehicles serve as nodes, the edges represent the interaction relation between the vehicles, the weights are distributed for the edges, the random noise obeying normal distribution is sampled, the state vectors are added, the robustness of the model can be enhanced, and accurate vehicle track prediction is achieved.
本发明公开了一种基于时空融合注意力的车辆轨迹预测方法,包括数据预处理模块DPM、数据预处理模块DPM、时间特征提取模块TEM、空间特征提取模块SEM、以及轨迹预测模块TPM。本发明使用了动态的无向图进行表示,其中车辆作为节点,而边表示车辆之间的相互作用关系,为边分配权值,采样了服从正态分布的随机噪声加入状态向量,能够加强模型鲁棒性,实现准确的车辆轨迹预测。
