基于文字定位和颜色检测的多车牌定位方法研究
Research on Multi-license Plate Location Based on Multi-algorithms
摘要
Abstract
License plate location is the key step in vehicle license plate recognition.License plate location can provide great convenience to next steps of license plate recognition.In order to improve the efficiency of different color license plate location,this method selects candidate region based on color detection and a text localization method based on maximally stable extremal regions, and combined with support vector machine(SVM)algorithm,precise location of vehicle license plate is achieved.In order to find all the potential license plate area,this method selects candidate region of license plate based on text localization and color detec?tion,and then tilt correction is done for the candidate regions of license plates.Finally,the license plate candidate region feature in?formation is extracted as the feature information input to support vector machine to identify and locate the license plate region.The experiment results show that this method can eliminate the background interference.The recognition effect and rate of multi-license plate location are high.The experiment results show that this method can achieve high localization rate for most kind color of license plates under complicated background.关键词
