【摘要】：随着国民经济的飞速发展和人们物质生活水平的不断提高,我国的机动车普及率越来越高,国内各大城市的机动车保有量呈爆炸式增长,由此引发的道路交通状况越来越频繁,与机动车有关的犯罪案件也逐渐增多,使得交通管理和城市治安日渐成为现代城市管理急需解决的重大难题。在城市的重要出入口、重要区域以及车流量大的道路上安装治安高清卡口系统,成为解决上述两大难题的主要手段之一。然而现阶段的治安高清卡口系统,无论是采用线圈触发式、全视频触发式或者线圈加视频触发式作为触发技术,都需要单独安装具有前端智能分析的高清工业级摄像机、车辆检测器、LED补光灯和高频闪光灯等设备。当使用线圈触发式时,还需要破坏路面敷设线圈,不仅增加了人力和物力的投入,也无法有效利用现有道路上安装的摄像机资源。本论文设计的虚拟卡口系统在充分讨论城市管理的需求以及高清卡口系统设计理念的基础上,探讨利用现有道路摄像机实现机动车辆信息实时提取和分析的问题,采用多帧差分、图像边缘特征分析、模式识别技术,设计一套集智能视频分析、图像处理、机动车辆信息提取于一身的智能监控平台,通过提取视频中机动车辆的详细信息,如车牌号码、车牌颜色、车身颜色、车辆徽标等,将记录上传到虚拟卡口平台,实时进行违法判断分析、关联车分析、黑／白名单比对、假／套牌车分析,对嫌疑车辆进行告警处理。虚拟卡口平台的设计与普及,可有效解决高清卡口系统建设成本高、工程施工复杂、与现有资源结合不紧密的弊端。
[Abstract]:With the rapid development of national economy and the continuous improvement of living standards, China's motor vehicle motor vehicle is gaining popularity, the domestic each big city population exploded, resulting in road traffic is more and more frequent, and vehicle related crime cases has gradually increased, which makes the traffic management and city security has become a major problem of modern city management needs to be resolved. At the entrance of the city, public security system installation area and HD traffic on the road, become one of the main means to solve the two major problems. However, at this stage the security HD system, whether it is triggered by a coil, the whole video trigger type or coil with video triggered as a trigger technology, need to install a separate HD camera with industrial intelligent analysis, vehicle detector, LED High frequency flash lights and other equipment. When using the trigger coil, also need to destroy the road laying coil, not only increases the input of manpower and material resources, can effectively utilize the camera installed on the road to existing resources. The design of the virtual entrance system to a fuller discussion of city management needs and the basic design concept of HD the bayonet system, to explore the use of the existing road motor vehicle camera to realize real-time information extraction and analysis of the problem, the multi frame difference analysis, image edge feature, pattern recognition technology, design a set of intelligent video analysis, image processing, intelligent monitoring platform for information extraction in a motor vehicle, through the detailed information of motor vehicle the extraction of the video, such as license plate, license plate color, body color, vehicle logo, the recording uploaded to the virtual platform, real-time analysis of the illegal judgment, Correlation analysis of the car, the black / white list comparison, analysis of false / clone car, the suspect vehicle alarm processing. With the popularization of virtual design platform, which can effectively solve the problem of high cost HD system construction, engineering construction is complex, not closely combined with the drawbacks of existing resources.
