摘    要:在电能表标牌OCR的识别过程中,标牌上的透明薄膜经常出现皱褶,使得待识别字符极易受到反射光遮挡,从而增加了OCR的识别难度和识别错误率。提出一种位置对称的双光源图像合成法,用该方法检测了多个贴有皱褶薄膜层的电能表标牌,经实例验证,相较于单光源的识别错误率大幅度降低,这有效解决了电能表标牌OCR中薄膜反光干扰问题。

关 键 词:OCR  双光源  图片合成  电能表标牌

LabeI Character Recognition Based on Image Composition of DoubIe Light Sources
Abstract:The Watt-hour meter sign of transparent fiIm often appears corrugated surface during the OCR process,which makes waiting characters are screened by refIected Iight easiIy,increases the difficuIty of OCR recognition and discriminating error rate.This paper presents a symmetricaI site of doubIe Iight sources image composition method,which is used to identify the number of watt-hour meter signs with corrugated surface.It has been verified by exampIes that compared with singIe Iight source reduced greatIy the discriminating error rate,and soIved effectiveIy the watt-hour meter sign OCR of refIective fiIm interference probIem.
Keywords:OCR  doubIe Iight sources  image composition  watt-hour meter IabeI
