在分析条码字符常规识别方法的基础上,针对因扫描倾斜角和扫描速度改度引起的首读率不高问题,提出了模糊识别方法。理论分析和抽样结果都表明,在硬件设备和印刷质量相同的条件下,该方法的识别首读率明显高于常规识别方法。
Based on the analysis of the conventional recognition method of bar code characters, aiming at the problem of low initial reading rate caused by the change of scanning tilt angle and scanning speed, a fuzzy recognition method is proposed. Both theoretical analysis and sampling results show that the recognition rate of this method is obviously higher than that of the conventional recognition method under the same hardware and printing quality.
