摘　　要：介绍基于SOPC技术的PET瓶缺陷检测系统的软、硬件设计方法。利用SOPC Builder在FPGA芯片EP2C35F6726C上配置的NIOSⅡ软核处理器作为控制核心,在Avalon总线上挂接接口模块和用户自定义逻辑模块,于NIOSⅡ中使用C++编程实现图像检测判别准则,并加上FPGA的外围单元,共同完成系统主要的功能设计。实验结果表明,该设计方法可行、可靠,检测效果快速精确。该设计在图像处理中采用并行处理设计,其应用上具有一定的帮助性和可借鉴性,也证明FPGA在图像处理方面的优越性。采用FPGA并行处理的方法进行图像识别,系统处理速度快、集成度高、成本低、维护方便。How to design software and hardware of PET bottle defect detection system based on SOPC is introduced. The NIOS Ⅱ soft- core is used to be as the controller in the FPGA chip EP2C35F6726C. Designing some interface modules and user-defined logic modules on the Avalon, using C^＋＋ program to achieve image processing in the NIOS Ⅱ, also some peripheral components is needed in the system design. The results show that the design is feasible and reliable,efficient and accurate test. It has some help on parallel image processing,at the same time, prove that FPGA method in image processing is superior. Using FPGA parallel processing method to achieve image recognition. The system is high efficiency, high integration, low cost and easy maintenance.
