Floating car counting method based on video monitoring processing technology

Abstract

The invention relates to a floating car counting method based on the video monitoring processing technology. Compared with the prior art, the defect that floating cars can not be comprehensively counted through the video image technology is solved. The floating car counting method includes the following steps: carrying out preprocessing, wherein virtual line circles and detection lines are drawn for measured lanes, and manual counting in the car saturation state is carried out; building an initial background image, and constructing a background image BG with a frame difference method; monitoring cars, and forming binary images O<bject> of the cars through difference images DI; obtaining the information of images of the cars in the virtual line circles; judging the state of the cars in the virtual line circles, wherein whether the cars exist in the virtual line circles or not and whether the virtual line circles are in the saturation state or not are judged by calculating the ratio of intersection images to the detection lines; counting the floating cars, wherein the floating cars in the non-saturation state and the floating cars in the saturation state are respectively calculated, and the floating car counting result is obtained. By means of the floating car counting method, the flow number of the cars in the non-saturation state can be obtained, the flow number in the saturation state can further be obtained, and the counting result is more accurate.

Description

technical field [0001] The invention relates to a statistical method for floating cars, in particular to a statistical method for floating cars based on video surveillance processing technology. Background technique [0002] With the rapid development of my country's economic and social construction, the number of car ownership has gradually increased. The increase in car ownership has intensified road traffic congestion and frequent traffic accidents. The use of remote road systems in traffic management greatly reduces manpower consumption. In order to effectively monitor the road traffic and quickly make traffic guidance control decisions in response to dynamic changes in traffic conditions, real-time detection of road traffic floating vehicles is required. [0003] At present, the methods for extracting floating cars mainly include: 1. Use wireless microwaves, thunder waves, etc. to obtain vehicle speed related information. It is more common to install radar devices on ...
