The invention relates to a black smoke vehicle snapshot system of a large truck with a separated truck head and carriage. The black smoke vehicle snapshot system comprises a video data acquisition assembly; the video information acquisition assembly comprises a same-direction snapshot unit and an opposite-direction snapshot unit which are installed above a road, a side-direction snapshot unit installed on the side edge of the road, and a service processor which is in communication connection with the same-direction snapshot unit, the opposite-direction snapshot unit and the side-direction snapshot unit. The same-direction snapshot unit performs video acquisition on the tail part and the side surface of the vehicle, and the opposite-direction snapshot unit performs video acquisition on thefront part and the side surface of the vehicle; the side-direction snapshot unit performs video acquisition on a single side surface of the vehicle and a gap between a vehicle head and a carriage; andthe service processor processes the acquired video so as to compare the acquired video with a pre-stored database to obtain discharged smoke data. The black smoke vehicle snapshot system is low in false identification rate and high in detection precision; the system is high in environmental adaptability, is not interfered by environmental conditions, achieves the all-weather recognition and detection of the black smoke vehicle, and solves a problem that black smoke emitted from a long carriage cannot be recognized.
本发明涉及一种车头、车厢分离的大型货车的黑烟车抓拍系统,包括视频数据采集组件;视频信息采集组件包括安装于道路上方的同向抓拍单元、对向抓拍单元,安装于道路侧边的侧向抓拍单元,以及分别与同向抓拍单元、对向抓拍单元、侧向抓拍单元通信连接的业务处理机。同向抓拍单元对车辆尾部和侧面进行视频采集,对向抓拍单元对车辆前部和侧面进行视频采集;侧向抓拍单元对车辆单一侧面,以及车头与车厢之间的间隙进行视频采集;业务处理机对采集的视频进行处理,以和预存的数据库对比,得出排出的烟雾数据。黑烟车抓拍系统误识别率低,检测精度高;环境适应能力强,不受环境条件干扰,全天候进行黑烟车识别检测,解决无法识别长车厢冒黑烟的问题。
