The invention relates to the technical field of automatic driving, in particular to a multi-scene trajectory prediction method and device, a medium and a vehicle, and aims to solve the problem that an existing trajectory prediction method is low in prediction precision. In order to achieve the purpose, the multi-scene trajectory prediction method comprises the steps that scene information of a scene to be concerned is obtained, and the scene information at least comprises a scene type, scene labeling information, a trajectory ID of a first target and first time information; inputting the scene annotation information into a trajectory prediction model to obtain a prediction trajectory of at least one second target in the scene annotation information; determining an evaluation index of a trajectory prediction model based on the trajectory ID of the first target, the first time information and the predicted trajectory of the at least one second target; and under the condition that the evaluation index meets a first preset condition, performing trajectory prediction on the first target by using a trajectory prediction model. In this way, the prediction trajectory with high accuracy is obtained, and the safety and stability of the vehicle are guaranteed.

    本发明涉及自动驾驶技术领域,具体提供一种多场景轨迹预测方法、设备、介质及车辆,旨在解决现有的轨迹预测方法的预测精度较低的问题。为此目的,本发明的多场景轨迹预测方法包括:获取待关注场景的场景信息,场景信息至少包括场景类型、场景标注信息、第一目标的轨迹ID和第一时间信息;将场景标注信息输入轨迹预测模型,获得场景标注信息中至少一个第二目标的预测轨迹;基于第一目标的轨迹ID、第一时间信息和至少一个第二目标的预测轨迹确定轨迹预测模型的评估指标;在评估指标满足第一预设条件的情况下,利用轨迹预测模型对第一目标进行轨迹预测。如此,获得了精确度较高的预测轨迹,保证了车辆的安全性和稳定性。
