Abstract

The invention provides a method of a vehicle-mounted line pressing violation identification based on the mobile machine vision technology. The method comprises a road marking identification method based on Hough transformation and the perspective principle and a vehicle positioning method based on vehicle bottom shadow detection. The environmental textures can be eliminated by the detection method with combination of Hough transformation and the perspective principle so as to accurately identify the road marking. Besides, the vehicle can be positioned under various light environments by the positioning method with combination of vehicle bottom shadow detection. The method has the characteristics of low cost, high operation efficiency, high identification accuracy and convenient installation so as to enhance the effectiveness of urban road traffic enforcement.

Description

technical field [0001] The invention relates to the field of machine vision, in particular to an automatic identification method for illegal vehicles in video captured by a mobile camera using multiple image processing methods with high efficiency and low cost. Background technique [0002] Urban transportation systems often face the problem of insufficient monitoring of violations. In order to ensure the effectiveness and coverage of monitoring, prevent traffic participants from evading monitoring in various ways, and improve the efficiency and reliability of urban traffic systems, it is urgent to establish a scientific and effective traffic behavior monitoring system. [0003] At present, it is difficult to conduct mobile traffic video monitoring. The main reason is that the images captured by mobile cameras are varied, and it is difficult to effectively analyze and identify a single mode; the computing power and storage space of mobile devices are limited, which cannot me...
