The invention provides a traffic flow statistics device, which belongs to the technical field of traffic flow statistics and comprises a data acquisition module for acquiring a real-time traffic video stream and intercepting pictures in the video stream by adopting a set frame number; the scene modeling module is used for carrying out mathematical modeling on a scene in the picture and segmenting a background and a foreground; the scene filtering module is used for removing vehicle shadows and color blocks by using a texture edge method and overcoming the influence caused by vehicle shielding; the flow analyzer is used for analyzing traffic flow data according to the pixel characteristics and the foreground data and outputting the traffic flow data; the traffic flow analyzer judges the traffic flow through the interval between two adjacent pictures and the difference degree between the pictures, so that the judgment accuracy and efficiency of the traffic flow can be remarkably improved, the influence of static vehicles and surrounding scenes can be eliminated, and the traffic flow can be accurately counted.
本发明提出一种交通流量统计装置,属于交通流量统计技术领域,包括:数据获取模块,获取实时交通视频流,采用设定帧数截取视频流中的图片;场景建模模块,将图片中的场景进行数学建模,分割出背景和前景;场景过滤模块,利用纹理边缘方法去除车辆阴影和色块,克服车辆遮挡造成的影响;流量分析器,利用流量分析器根据像素特征和前景数据分析车流量数据并输出;流量分析器时通过相邻两个图片之间的间隔,通过图片之间差异度来判断车流量能够显著提高车流量的判断精确度和效率,可以排出静止车辆以及周围场景做出的影响,从而对交通流量做出准确的统计。
