    • A system for using OCR processing to read human readable characters that correspond to an unsuccessfully decoded code word in a bar code symbol. An imaging system captures an image of a label that includes a bar code symbol and corresponding human readable characters. The system attempts to decode the bar code symbol by decoding each of the constituent bar code characters. If a bar code characters is not successfully decoded, the system locates the associated human readable text and segments the text into individual character images. The unsuccessfully decoded bar code character is mapped to one or more of the alphanumeric character images, which are converted into text characters. The resulting ASCII data is used to create a substitute bar code character in the bar code symbology. After the bar code symbol is decoded using the substitute bar code character, the symbol is validated through check summing or other means.
    • 一种用于使用OCR处理来读取与条形码符号中未成功解码的代码字相对应的可读字符的系统。 成像系统捕获包括条形码符号和对应的可读字符的标签的图像。 系统尝试通过解码每个组成的条形码字符来解码条形码符号。 如果条形码字符未成功解码,则系统定位相关联的人类可读文本,并将文本分割成单个字符图像。 未成功解码的条形码字符被映射到一个或多个字母数字字符图像,其被转换成文本字符。 所得到的ASCII数据用于在条形码符号系统中创建替代条形码字符。 在使用替代条形码字符对条形码符号进行解码之后,通过校验和或其他方式对符号进行验证。
