Embodiment Construction

[0083] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0084] see figure 1 , the algorithm of the present invention is mainly composed of five parts in the implementation process, specifically the preprocessing part, the mapping relationship establishment part, the vehicle projection sequence extraction part, the vehicle space positioning part and the straight line fitting calculation speed part. The method described in the present invention is in principle applicable to video images of various resolutions. Due to the high resolution of high-definition video and the large amount of data, in order to reduce the amount of calculation, in the image preprocessing stage, the resolution conversion such as horizontal and vertical sampling is performed on the collected images. At the same time, the image is converted into a grayscale image through the transformation relationship from RGB...

Abstract

The invention provides a method for acquiring a vehicle speed from a road monitoring video. The method comprises five main steps: respectively pre-treatment, mapping relationship establishment, vehicle projection sequence extraction, vehicle space positioning and quick-frozen fitting.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, in particular to a method for acquiring vehicle speed from road monitoring video. Background technique [0002] With the continuous development of society, the pressure on road traffic is increasing day by day, and the collection of road traffic information is diversified. And our country is in the period of vigorous construction of intelligent transportation, so the collection and intelligent monitoring of road traffic parameters are also gradually strengthened. [0003] Traditional geomagnetism and other traffic parameter detection equipment are easily damaged and inconvenient to maintain. In this context, with the gradual coverage of road video surveillance, more and more products use video-based traffic parameter detection methods. Among them, vehicle speed detection is an important part of traffic parameter investigation, and more and more video-based vehicle speed detec...
