摘要
为了提高印刷缺陷检测准确性与效率,满足缺陷检测的实时性,提出了机器视觉技术应用于印刷缺陷在线检测并研究检测过程中的相关问题.设计印刷缺陷在线检测的方案及以数字信号处理器DSP为核心的视觉在线检测系统的硬件结构组成.研究图像预处理、图像匹配与缺陷检测的算法并加以改进使其满足缺陷检测的实时性.开发印刷品缺陷视觉检测软件,对缺陷检测流程进行仿真,验证检测方案与图像处理算法的可行性.
In ordert to improve the efficiency of inspection for printed defect and meet the real-time requirement for printed defect inspection, the article is proposed to application of machine vision on on-line inspection for defect and studies related problems. The article designs the program of on-line inspection for printed defect and visual on-line inspection system of the hardware components based on DSE The article also studies algorithm of image pre-processing, image processing and image registration. We improve these algorithms to meet the real-time requirement for printed defect inspection. We design the soilware named printed defect machine vision system. It proves that the inspection program and algorithm of image processing is feasible through simulating process of defect inspection.
