基于嵌入式图像处理的玻璃缺陷在线检测技术研究

在玻璃生产过程中，由于种种原因会产生一些缺陷，例如气泡、结石等，这些缺陷会严重影响玻璃品质，必须对玻璃缺陷进行在线检测。本文设计了一个基于嵌入式图像处理技术的在线检测系统，以TMS320C6711—150DSP和EPM1270GT144C5CPLD芯片为控制核心，加上外围功能模块，构成了系统的硬件部分；再按目前流行的数字图像处理技术来设计软件流程。本系统对于提高玻璃缺陷在线检测的工艺水平、灵敏度、精度等级以及提高产品质量、生产效率和自动化水平，降低投资及运行成本都将有着极其重要的现实意义。

Study of on-line glass defect inspection system based on embedded image processing

Some defects are produced during the glass production for some reasons, such as bubbles, stones. These defects will badly affect the quality of glass. So it is necessary to detect the glass defects in glass production on-line. The on-line glass defect inspection system is introduced in this article by using TMS320C6711-150 DSP and EPM1270GT144C5 CPLD as control part and functional models as periphery to make up the hardware part. The software system is designed according to the nowadays-popular digital image processing technology. This system will be the important thing to improve the production level, intelligent grade of on line glass defect inspection; increase the product quality, production efficiency and automation level, decrease the investment and cost of that.
