The invention belongs to the field of environmental protection detection, and particularly relates to a heavy smoke vehicle snapshot video post-processing system and method. A front and rear camera combination linkage mode is used to identify license plates in a vehicle head and a vehicle tail, and a cross check and comprehensive analysis method is used to judge the correct license plate of a vehicle, thereby improving the accuracy of license plate identification. A heavy smoke vehicle snapshot instrument is introduced to the front end of a monitoring point to screen and intercept vehicle passing videos of real-time videos. An inference engine is placed at a central end, vehicle passing videos of the plurality of monitoring points are analyzed and processed at the same time, and whether the vehicle is a heavy smoke vehicle is judged.
本发明属于环保检测领域,特别涉及一种黑烟车抓拍视频后处理系统及方法,采用前后摄像机组合联动方式,对车头和车尾的车牌进行识别,采用交叉校验、综合分析方法判断车辆正确的车牌,从而提高车牌识别的准确率。在监控点位前端引入黑烟车抓拍仪,对实时视频进行过车视频筛选截取。将推理机放置于中心端,同时分析处理多个监控点位的过车视频,判定是否为黑烟车。
