Video traffic flow counting technique based on virtual coil technology

Abstract

The invention aims at providing a video traffic flow counting technique based on a virtual coil technology. The video traffic flow counting technique based on the virtual coil technology can be applied to the field of intelligent transportation monitoring, the problem of vehicle sheltering and the problems of repeat counting and counting missing, caused by driving lane changing, even driving line pressing and the like, are solved effectively, the vehicle misjudgment caused by foreground breakage is reduced, the repeat counting is avoided, and the counting accuracy in multiple experimental scenes is stable and is over 96%; and the video traffic flow counting technique has the advantages of extensibility, independence, easiness in operation and the like. The technique provided by the invention comprises the following steps of (1) modeling and updating a background by using an improved ViBe algorithm, and extracting motion foreground from videos; (2) reducing error interference in the motion foreground by adopting an image preprocessing mechanism; (3) drawing virtual coils according to lanes; (4) carrying out detection, counting and sum statistics on vehicles passing through the virtual coils, and solving the problems of the misjudgment, repeat counting and counting missing of the vehicles; and (5) integrating the results, obtained in the step (1) and the step (2), and an analytical result on the result obtained in the step (4) to extended application.

Description

technical field [0001] The invention relates to the fields of intelligent traffic video monitoring, traffic parameter collection and the like. Background technique [0002] The Intelligent Transportation System (ITS for short) is the development direction of the future transportation system. It effectively integrates advanced information technology, data communication transmission technology, electronic sensor technology, control technology and computer technology, etc. It is a real-time, accurate and efficient integrated traffic management system established by the traffic management system that plays a role in a wide range and in an all-round way. In intelligent transportation systems, traffic flow is an important traffic parameter. Traditional traffic flow collection systems usually use technologies such as gratings and induction coils. These technologies are complex to operate, high in construction costs, not easy to maintain, and will damage traffic roads and other faci...

Problems solved by technology

[0003] Because the results of motion detection and motion tracking have too much error, and it is difficult to solve the problem of vehicle occlusion, the accuracy of collecting traffic flow by using video information is often very low
