The invention provides a highway traffic flow statistics method. The method comprises the steps that detection areas are set at fixed positions on both sides of a lane in a monitoring area of a highway; video data in the monitoring area are collected and pre-processed; a mixed Gaussian model is used for background modeling, and background pixels are separated from an original image; 4 a moving object is extracted from a monitoring video image; 5 the trajectory information of the moving object is recorded to identify the vehicle information, and the information is marked; and 6 marked vehiclesare tracked and counted to calculate the traffic flow. According to the highway traffic flow statistics method, through real-time monitoring of the road traffic flow, vehicles on the road can be accurately and efficiently detected, tracked and counted in all directions and in real time; and the method can be applied to complex scenes, and has the advantages of high detection accuracy, great instantaneity and important application value.
Description
technical field [0001] The invention belongs to the technical field of security monitoring, in particular to a method for counting traffic flow on expressways. Background technique [0002] With the rapid development of modern economy, expressway transportation has become an important mode of transportation in the transportation industry. In order to ensure smooth traffic and driving safety, thereby improving environmental quality, traffic flow detection on expressways is particularly important. The existing traffic flow detection methods in current traffic are mainly divided into three parts: extracting moving targets from image sequences, identifying the extracted targets and counting vehicles. [0003] The traditional method for extracting moving objects is the background difference method, which uses the weighted average method to update the background, but the update effect is not ideal, resulting in incomplete extraction of moving vehicles, which affects the accuracy ...
