Abstract:

Aiming at detecting the violation behavior of vehicle's line pressing,this paper proposes a method of vehicle's pressing line detection based on computer vision.First,the Hough transform method is applied to extract the yellow lines from traffic video images automatically;second,the background difference method is used to extract vehicles from images,and the otsu method segments the vehicles out,thus getting vehicle's position;Finally,the overlap of the yellow line area and vehicle area can determine the vehicle's line pressing.Experimental results demonstrate that this method can meet the requirements of accuracy and efficiency.

Key words: image processing;line extraction;vehicle detection
