摘　　要：本文介绍了基于遗传算法的最大类间方差法在PDF417码检测技术在图书馆自动化管理中的实际应用。针对获取的PDF417码图像时在光照不均匀、强光干扰、缺损以及产生旋转角度等条件下产生对比度低,亮度过大或过小等方面不足,选择了基于遗传算法的最大类间方差法对图像进行阈值分割。文中给出了遗传算法的基本操作过程和算法流程图,实验结果表明,该方法可以很好的保留PDF417码图像,并滤除掉背景信息,明显提高PDF417码的二值化分割效果和识别率,进而节约了服务器资源提高了图书馆管理系统的使用效率及运行速度。The practical application of OTSU method based on genetic algorithm in PDF417 code recognition technology in library automatic management is introduced in the paper.In order to fix the shortcomings of low contrast and too high or too low brightness of PDF417 code image which are caused by uneven illumination,highlight disturbance,defect and rotation angle,the threshold segmentation of the image is achieved by OTSU method based on genetic algorithm.The basic operation process and algorithm flowchart of genetic algorithm are presented in the paper.The experimental results show that this method can keep the PDF417 code image and eliminate the background information and can improve obviously the binarization effect and recognition rate of PDF417 code and saving server resources.Moreover,improving service efficiency and operating speed of library management system.
