The invention provides a trajectory prediction model generation method and device and a model training method and device, which can be applied to the technical field of intelligent driving. The trajectory prediction model generation method comprises the steps of determining a target task category corresponding to a first driving scene according to first scene information associated with the first driving scene; when it is determined that a plurality of trajectory prediction models pre-stored in a model library do not contain a target trajectory prediction model corresponding to the target task category, calling a parameter adjustment model from the model library, and calling at least one trajectory prediction model from the plurality of trajectory prediction models as a basic trajectory prediction model; updating parameters of the parameter adjustment model based on the first scene information to obtain a target parameter adjustment model; and adjusting parameters of the basic trajectory prediction model by using the target parameter adjustment model to generate a target trajectory prediction model.

    本公开提供了一种轨迹预测模型生成方法及装置、模型训练方法及装置,可以应用于智能驾驶技术领域。该轨迹预测模型生成方法包括:根据与第一驾驶场景关联的第一场景信息,确定与第一驾驶场景对应的目标任务类别;在确定模型库中预存的多个轨迹预测模型中不包含与目标任务类别对应的目标轨迹预测模型情况下,从模型库中调用调参模型,以及从多个轨迹预测模型中调用至少一个轨迹预测模型作为基础轨迹预测模型;基于第一场景信息对调参模型的参数进行更新,得到目标调参模型;利用目标调参模型对基础轨迹预测模型的参数进行调整,生成目标轨迹预测模型。
