Traffic flow counting device and counting method

Abstract

The invention discloses a video-based traffic flow counting device, which comprises a camera, a front background partitioning unit, a vehicle location tracking unit, virtual induction coils and a counting unit, wherein the camera is used for shooting a video image; the front background partitioning unit is used for partitioning a video picture shot by the camera into a foreground and a background; the foreground refers to running vehicles, the background is a static road; the vehicle location tracking unit is used for positioning vehicles in the foreground and assigning different ID (identity) numbers to each running vehicle; more than one virtual induction coils is arranged on the background according to the quantity of lane lines of the road according to the arrangement of real induction coils; and the counting unit is used for counting the quantity of vehicles passing by each virtual induction coil, and counting by one once a vehicle enters and exits. The traffic flow counting device has the advantages that: the traffic flow can be recorded and analyzed accurately in real time through videos, and a precondition is provided for the realization of intelligent traffic guidance and control.

Description

technical field [0001] The invention relates to a video-based traffic flow statistics device and a statistics method. Background technique [0002] Since the 1960s, the world economy has entered a period of rapid growth. With the increasing maturity of technologies such as computers, communications and electronics, informatization and intelligence have increasingly become important factors affecting future social and economic development. In such a general background, a key factor to accelerate economic development is to realize convenient and fast transportation. [0003] However, with the progress of urbanization in the world and the popularization of automobiles as the main means of daily transportation, problems such as increased traffic congestion, frequent traffic accidents, and deterioration of the traffic environment have become increasingly serious in both developing countries and developed countries . [0004] The intelligent transportation system is currently r...

Problems solved by technology

[0004] The intelligent transportation system is currently recognized as the best measure to solve the problem of urban traffic congestion in the world. The current traffic flow statistics are mainly processed by the ground induction coil. It is necessary to cut the road and install the ground induction coil, which will damage the road surface. , it is not applicable to some areas where the road surface cannot be cut
