The invention discloses an intelligent traffic vehicle license plate shielding recognition system based on the Beidou positioning analysis technology, the intelligent traffic vehicle license plate shielding recognition system based on the Beidou positioning analysis technology comprises a difference module and a vehicle license plate positioning module, the difference module comprises a base station, a mobile station receiver and a difference model, the difference model comprises a pseudo-range difference model and a carrier phase difference model, and the vehicle license plate positioning module comprises a color image graying system, an image binarization system, a filtering processing system, an image horizontal edge detection system and a license plate searching and intercepting system. According to the method, a pseudo-range difference model technology and a carrier phase difference technology are respectively adopted in a Beidou satellite navigation system for positioning, a new method is subsequently provided for character segmentation of a covered license plate, row and column pixels are calculated and then compared with a set threshold value, the starting position and the ending position of characters are judged, and the license plate is subjected to character segmentation. Therefore, the characters are segmented and quickly and effectively recognized.

    本发明公开了基于北斗定位分析技术的智能交通车辆遮牌识别系统,基于北斗定位分析技术的智能交通车辆遮牌识别系统,包括差分模块及车辆牌照定位模块,所述差分模块包括基准站、移动站接收机及差分模型,所述差分模型包括伪距差分模型及载波相位差分模型,所述车辆牌照定位模块包括彩色图像灰度化系统、图像二值化系统、滤波处理系统、图像水平边缘检测系统、牌照搜索及截取系统。本发明在北斗卫星导航系统中分别采用伪距差分模型技术及载波相位差分技术进行定位,后续对被遮盖后的车牌在字符分割方面提出了一种新的方法,计算行列像素后与设定阈值进行比较,判断字符的开始和结束位置,从而对字符进行分割并快速有效识别。
