| 摘 要： | 本文针对车牌识别系统在车牌图像质量不高时识别准确率较低的问题,提出了一种多帧图像综合算法,来更全面地利用车牌图像中所含有的有用信息,以达到提高车牌识别准确率的目的。首先利用图像配准算法对从视频图像中抽取的几帧图像进行配准,然后利用像素值取大算法进行综合,最后得到一幅综合后的车牌图像。实验表明,经过该算法综合后的车牌图像比原图像更接近真实的车牌图像,能够更好地适用于车牌识别,从而提高车牌识别的准确率。

| Abstract: | A Multi-frame images integrated algorithm is proposed in the paper,in order to fully use the License plate image information and improve the accuracy of License Plate Recognition as the License plate image quality is not high in the License Plate Recognition system. Firstly,image registration algorithm is carried out to register several frames extracted from video images. Then pixel maximum value algorithm is applied to integrate the frames. Finally,an integrated plate image is got after the algorithm. The ... |
