Design of license plate recognition system based on LabVIEW and Vision Assistant

文章提出了一种基于LabVIEW和Vision Assistant的车牌识别方案。系统使用Vision Assistant的颜色阈值、高级形态学及光学字符识别等函数,实现了对车牌图像的预处理和车牌区域定位以及车牌字符分割、字符训练和识别,使用LabVIEW程序完成车牌的显示。使用数百张车牌图像对该系统进行验证,结果证实该方案是可行的,系统是可靠的,可以快速、准确定位和识别车牌。

This paper presents a license plate recognition scheme based on LabVIEW and Vision Assistant.By using the functions of Vision Assistant,such as color threshold,advanced morphology and optical character recognition,the system realizes the pre-processing of license plate image,license plate area positioning,license plate character segmentation,character training and recognition,and then uses the LabVIEW program to complete the license plate display.Hundreds of license plate images were used to verify the system.The results show that the scheme is feasible and the system is reliable,which can quickly and accurately locate and recognize license plates.
