The invention discloses an automatic identification method and device for a crossing scene of a pedestrian ahead of a vehicle, a medium and the vehicle, and the method comprises the following steps: obtaining target list data, and screening target data corresponding to a pedestrian type from the target list data; performing secondary screening on the target data corresponding to the pedestrian type to obtain the target data corresponding to the pedestrian crossing the road; performing data cleaning on the target data corresponding to the pedestrians crossing the road to remove abnormal data, and fitting a pedestrian trajectory and a vehicle trajectory according to the cleaned target data corresponding to the pedestrians crossing the road and the GPS data; and when the pedestrian trajectory and the vehicle trajectory intersect in a close distance, determining the current scene as a vehicle front pedestrian crossing scene. Therefore, automatic identification of the crossing scene of the pedestrian ahead of the vehicle is realized based on the kinematics parameters, the algorithm is simple, convenient and feasible, the calculation complexity is low, data convenience is provided for PCW and AEBP function applications in an ADAS function scene, and pedestrian collision accidents are effectively prevented.
本发明公开了一种车前行人横穿场景的自动识别方法、装置、介质和车辆,其中,方法包括以下步骤:获取目标列表数据,并从目标列表数据中筛选出行人类型对应的目标数据;对行人类型对应的目标数据进行二次筛选,获得横穿道路行人对应的目标数据;对横穿道路行人对应的目标数据进行数据清洗,以去除异常数据,并根据清洗处理后的横穿道路行人对应的目标数据和GPS数据,分别拟合行人轨迹与本车轨迹;在行人轨迹与本车轨迹近距离相交时,将当前场景确定为车前行人横穿场景。由此,基于运动学参数实现对车前行人横穿场景的自动识别,且算法简便易行,计算复杂度低,有利于为ADAS功能场景中的PCW和AEBP功能应用提供数据便利,有效预防行人碰撞事故的发生。
