Embodiment Construction

[0039] Preferred embodiments of the present invention will be described in detail below.

[0040] Such as image 3 As shown, the discriminative process of the traffic congestion discrimination method based on video detection technology proposed by the present invention is: obtain road video images by video acquisition equipment; extract pictures from video images; convert pictures into gray scale images; Establish and update the background model of the degree map; extract the foreground and remove the noise such as leaves in the foreground; use the background and foreground information to calculate the road state evaluation parameters: road occupancy rate, occupancy variance and the absolute value of occupancy rate change; establish a fuzzy discriminant model Judging whether there is traffic congestion; sending back the congestion prompt information.

Abstract

The invention discloses a traffic jam judging method based on a video detection technology. By adopting a digital image processing technology, the background model of a traffic video image is established, foreground extraction and foreground de-noising are carried out on the background model, road occupancy is calculated, and a traffic jam judging model is established, thus finishing the judgment of the traffic jam state by the four steps. The traffic jam judging model comprises a jam fuzzy clustering judger and an auxiliary judger, the video image processing technology is utilized to obtain one parameter, i.e. the road occupancy, thus calculating the occupancy variance and the absolute value of occupancy variation, and being capable of finishing the judgment of the traffic jam state by using the three finite parameters.

Description

technical field [0001] The invention relates to the field of road traffic state detection, in particular to a method for judging traffic congestion based on video detection technology. Background technique [0002] With the rapid development of the economy, the number of motor vehicles owned by the urban population is also increasing rapidly. The growth rate of vehicles far exceeds the growth rate of roads, resulting in increasingly serious traffic congestion and frequent traffic accidents. Therefore, it is of great significance to monitor the state of road congestion through scientific and technological means. [0003] Traffic congestion detection methods include buried induction detection, microwave detection, GPS floating car detection technology, video detection technology, etc. Buried induction detection lays induction coils on various sections of the road, which has the disadvantages of being easily damaged, difficult to repair, and complicated construction; microwave...
