A vehicle window throwing object detection method based on a real-time video comprises the following steps: acquiring and decoding a video stream, processing each decoded frame of image by using the relevance of front and back frames in a video image sequence so as to detect the moving target areas of all images, extracting the moving target areas, tracking the extracted moving target areas, and finally, judging whether the moving target is a vehicle window throwing object or not according to the inherent position, size and motion characteristics of the thrown object, and if the moving targetis judged to be the vehicle window throwing object, identifying the license plate of the vehicle which throws the object. According to the invention, the vehicle window throwing object behavior in themonitoring video can be detected without human participation, the real-time performance can be ensured, the detection accuracy can be ensured, the license plate of the vehicle with the vehicle windowparabolic behavior can be identified, efficient and large-scale all-weather real-time monitoring can be achieved, time and labor are saved, and the problem of difficult management is solved.

    一种基于实时视频的车窗抛物检测方法,首先获取视频流并解码,再利用视频图像序列中前后帧的关联性对解码后的每帧图像进行处理,以检测出所有图像的运动目标区域,并提取运动目标区域,而后对提取的运动目标区域进行跟踪,最后根据被抛物品固有的位置、大小和运动特性,判断运动目标是否为车窗抛物,若判定运动目标为车窗抛物,则对抛出该物品车辆的车牌进行识别;本发明在不需要人为参与的情况下,可对监控视频中的车窗抛物行为进行检测,既能保证实时性,又能保证检测的准确率,还可对发生车窗抛物行为车辆的车牌进行识别,可实现高效大范围全天候实时监控,省时省力,同时还解决管理难问题。
