The Study Of Violations Detection Of Yellow Line Based On Viedo

In order to solve various problems caused by the rapid growing of surface traffic, the research of Intelligent Transportation System comes to an issue of consequence. As an important part of ITS, vehicle tracking and traffic incidents detection becomes a research focus all over the world. The sampling controlling card in ITS, this paper presents, meets the demand of adjusting the parameters of camera lens and sampling the traffic signal. Test turn out that the sampling controlling card can work durably and stably.This paper first introduces a system which can detect vehicle disobey the red light. then introduces a arithmetic with shadow elimination to solve the problem of violations detection of yellow line: by day,the quality of the image is good,this arthmetic uses a method which combine the line-frame detection and the HSV color information analysis.this method detect violations according as whether the line-frame of yellow is being destroyed. In order to solve the most important problem in apply instance—interference of shadow,we add HSV color information analysis in the area of yellow line which line-frame is being destroyed. If the shadow's proportion is below the threshold,then we determine vehicle violative of yellow line; at night,the quality of the image is not good, we calculate the grey image of differences to detect violations. besides,we use serial port correspondence to dynamically adjust the parameters of camera lens. by this way ,the high-quality video could be captured. Experiment results show that violations detection of yellow line and shadow elimination have good feasibility and effectiveness.
