The invention provides a method for constructing a traffic accident scene file. The method comprises the following steps: constructing an abstract description statement of a traffic accident scene according to an action sequence combination generated by an entity involved when a traffic accident occurs; wherein the abstraction description statement comprises information of a road scene where the entity is located and all entity actions forming the traffic accident; taking the road scene information in the abstracted description statement and parameters corresponding to the entity as key parameters for describing the traffic accident scene; and obtaining parameter values of the key parameters, and mapping the key parameters and the parameter values thereof to a scene description file in a preset format to form a traffic accident scene file. The finally obtained traffic accident scene file can be injected into simulation software to carry out simulation deduction on the traffic accident.
本发明提供了一种交通事故场景文件的构建方法,该方法包括:根据交通事故发生时所涉及的实体产生的动作序列组合构建交通事故场景的抽象化描述语句;其中,抽象化描述语句包括实体所处的道路场景信息及形成交通事故的全部实体动作;将抽象化描述语句中道路场景信息及实体对应的参数作为描述交通事故场景的关键参数;获取关键参数的参数值,将关键参数及其参数值映射至预设格式的场景描述文件中,形成交通事故场景文件。本发明最终得到的交通事故场景文件可以注入仿真软件以进行对交通事故的仿真推演。
