基于多光谱分析的烟包外观检测系统
|
摘要
目的为了解决卷烟厂在烟包外观检测中,包装纸与透明纸难以同时检测的难点,设计一种对称式多光谱分析的烟包外观检测系统,以用于FX-2型包装机。方法该系统选用可调式支架、稳定的LED、高速多光谱CCD光源来捕获卡槽中烟包的待测面,将获取的多光谱图像传入高性能工控机,并对各子带图像联合进行处理。结果该系统可以通过一次成像同时检测包装纸和透明纸。结论该系统结构合理,易于安装与维护,检测精度高,参数可调,系统稳定可靠。
The paper aims to solve the difficulty of simultaneous detection of packaging paper and transparent paper in cigarette factory and design a symmetrical multi-spectral analysis system for the appearance detection of cigarette packages to be used in FX-2 packaging machine. Adjustable bracket, stable LED and high-speed multi-spectral CCD light source were selected for the system to capture the cigarette pack surface to be measured in the chute. The multi-spectral image obtained was transmitted to high-performance industrial computer, and the sub-band images were processed jointly.The system could detect packaging paper and transparent paper simultaneously. Conclusion: The system has reasonable structure, easy installation and maintenance, high detection accuracy and adjustable parameters. It is a stable and reliable system.
