Smoky Vehicle Recognition Method Based on Gaussian Mixture and Autoregressive Moving Average Model

Abstract

The smoky car recognition method based on Gaussian mixture and autoregressive moving average model includes the following steps: (1) using Gaussian mixture model to detect vehicle moving targets from road surveillance video; (2) extracting three features of key areas of the vehicle, including Haar-like feature, co-occurrence matrix gradient direction histogram feature and local binary mode Fourier histogram feature; (3) use the autoregressive moving average model to model the continuous multi-frames of each feature, and get three different models ; (4) For the new vehicle target, the three models are used to classify the three features extracted from the key areas of the vehicle, and the classification results of different features and the comprehensive analysis of continuous multi-frames are used to determine whether the current video segment is black or not. The cigarette truck makes a judgment call. The invention can greatly save manpower and financial resources consumed by traditional methods, is beneficial to the acquisition and preservation of evidence, does not affect normal traffic, and can effectively improve law enforcement efficiency.

Description

technical field [0001] The invention relates to the technical fields of computer vision and pattern recognition, in particular to a black-smoky car recognition method based on a Gaussian mixture and an autoregressive sliding average model. Background technique [0002] On June 16, 2018, the Central Committee of the Communist Party of China and the State Council issued the "Opinions on Comprehensively Strengthening Ecological and Environmental Protection and Resolutely Fighting the Battle of Pollution Prevention and Control", pointing out that "the battle of pollution control from diesel trucks must be fought well,...to build a world of integration of space, earth, vehicles and people." Motor vehicle emission monitoring system, perfect motor vehicle remote sensing monitoring network". Diesel vehicles with serious pollution are also called smoky vehicles. Usually there will be thick black smoke at the exhaust holes. The pollution has always been the focus of motor vehicle poll...

AI Technical Summary

Problems solved by technology

[0003] At present, many cities still use road inspections, public reports and manual video surveillance to detect smoky vehicles on the road, which is time-consuming and laborious, and will also affect normal traffic operations, which is not conducive to the preservation of illegal evidence of related vehicles
