基于HSV空间和连通域的车牌定位研究
Research on License Plate Location Method Based on HSV Space and Connected Components
摘要
Abstract
With the fast development of Intelligent Transportation System( ITS) ,License Plate Recognition( LPR) is a key point of it.On the basis of current vehicle license plate location algorithm,a method for license plate location is proposed based on HSV space and connected components.The color information of license plate is used to get the possible plate region,and the connected region is obtained by mathematical morphology techniques.Based on the prior knowledge of the license plate aspect ratio,the candidate regions of license plate is searched and judged.Finally,the precise positioning for binary image of license plate is performed based on its character feature vertical direction to obtain the right license plate area.The experimental results show that the proposed algorithm can effectively locate the license plate.关键词
