The invention relates to an automatic driving vehicle driving scene reconstruction and decision deduction evaluation method and system, and the method comprises the following steps: reconstructing a driving scene in a virtual environment through employing the driving data of a certain moment in a real driving scene, and employing the moment as the starting moment of the virtual environment, updating the state information of all elements in the driving scene in the virtual environment at the next moment by using the scene reaction model, and obtaining a series of driving scenes of the virtual environment at continuous moments after iteration; wherein the scene reaction type model is formed by pre-training based on acquired driving data of the automatic driving vehicle at a plurality of continuous moments in a real world driving scene; and deducing and evaluating an automatic driving decision effect of the automatic driving vehicle based on the obtained driving scene of the virtual environment at the series of continuous moments. The method can be widely applied to the field of intelligent vehicles.
本发明涉及一种自动驾驶车辆驾驶场景重构及决策推演评估方法和系统,包括以下步骤:利用真实驾驶场景中某一时刻的驾驶数据在虚拟环境中重构该驾驶场景,并以该时刻作为虚拟环境的起始时刻,利用场景反应式模型对下一时刻虚拟环境中驾驶场景内所有元素的状态信息进行更新,迭代后得到一系列连续时刻的虚拟环境的驾驶场景;其中,所述场景反应式模型基于采集的自动驾驶车辆在真实世界驾驶场景中多个连续时刻的驾驶数据,预先训练而成;基于得到的一系列连续时刻的虚拟环境的驾驶场景,对自动驾驶车辆的自动驾驶决策效果进行推演和评估。本发明可以广泛应用于智能车辆领域。
