摘　　要：由于EPS格式为矢量类文件,无分辨率可言,很难利用数字图像处理技术来识别。针对EPS格式条形码识别过程中存在诸如受黑墨扩展因素造成了条码的条和空的比例不符,无法准确识别出正确的条码等问题,提出了一种基于二进制法解析EPS格式条形码,并对其进行识别,判断条码的准确度,这样可以提前检测出EPS格式条码的错误。对不同放大系数的条形码进行分析,从而避免生成胶片和印刷时的误差和浪费。实验结果证明效果显著。In view of vector class and without resolution rate of EPS format, it is difficult to use digital image processing technology for recognition. There are many influence factors to bar code recognition, such as ink spread during the printing process, bar codes are read as sequences of widths of bars and spaces, it makes wrong to compare such widths with each other. The EPS format bar code based on binary method which can judge the bar code accuracy; reduce the printing error;analyzed different amplifying coefficients of bar code; avoid generate film and printing error and waste is proposed. The result proves good.
