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...
