The invention discloses a road thrown object judgment and alarm method, system and device and a storage medium, and belongs to the technical field of thrown object detection and recognition. The method comprises the steps: building a related region based on a dynamic moving vehicle, carrying out the motion monitoring of a target in the related region, and preliminarily judging the target as a to-be-thrown object after the difference between the motion of the target in the related region and the motion speed of the vehicle exceeds a related threshold speed, continuously monitoring the motion state of the to-be-thrown object, judging that the to-be-thrown object is a thrown object when the to-be-thrown object is located outside the associated area of the vehicle and the motion speed of the thrown object is reduced to zero, and giving an alarm based on the number of lanes occupied by the thrown object and the number of the lanes; according to the method, the thrown object is identified by detecting the position and speed characteristics of the vehicle and the thrown object target, a monitoring method of a visual sensor is abandoned, the influence of weather and illumination on a monitoring result is eliminated, and a good monitoring effect can still be obtained at a long distance.
本申请公开了一种公路抛洒物判定和告警方法、系统、装置和存储介质,属于抛洒物检测识别技术领域。本申请的公路抛洒物判定和告警方法包括:基于动态运动的车辆构建关联区域,并对关联区域中的目标进行运动监测,在关联区域中的目标的运动与车辆的运动速度的差超过关联门限速度后将目标初步判定为待抛洒物,并持续监测待抛洒物的运动状态,在待抛洒物位于车辆的关联区域之外且抛洒物的运动速度降为零后判定待抛洒物为抛洒物,并基于抛洒物占据的车道数和车道号进行告警;本申请通过检测车辆和抛洒物目标的位置和速度特征对抛洒物进行识别,摒弃视觉传感器的监测方法,消除了天气和光照对监测结果带来的影响,在较远距离仍能获得较好的监测效果。
