摘　　要：针对目前塑料制品缺陷检测主要还是依靠人工检测和分拣,效率不高和生产过程自动化程度的不足,采用了一种基于FPGA的注塑制品缺陷检测的方法。通过CMOS图像传感器对注塑制品进行图像数据采集,然后利用Verilog HDL语言进行图像处理识别算法建模。下位机完成注塑制品图像数据的采集与处理,上位机完成图像的显示和工作模式的配置,上、下位机之间通过USB2.0进行数据的通信。实验证明,基于FPGA的注塑制品缺陷检测系统,检测精度高达98%以上。系统检测精度高,具有广阔的应用前景。Aiming at the detection of plastic products mainly rely on manual inspectionand sorting, inefficiency and lack of degree of automatization in the production process.We using a method to detect the defects of Injection molding products which based on FPGA.Through the CMOS image sensor of Injection molding products to collect image data,then use Verilog HDL language to process and identify algorithm image so that we can build model.The Lower machine complete the image acquisition and processing and build model of plastic products, PC display the image and finish the configuration of work mode.The two machine transmissing data by USB.2.0.Experiments prove that plastic products detection system based on FPGA can make detection accuracy ratio up to 98%.Higher precision detection system has a prospect application.
