Research Research on Tube-type Bottle Integrated Parameter Image Inspection System ABSTRACT Machine vision is one of the most important technologies in medicine packaging and food processing industries，which would flourish the market in the future．And meanwhile， as锄emerging a[ea．the inspection of medical tube-type bottle produces a large demand inland,which lcads automatic detection based on machine vision to be all important subjeet of OUr current research．Aiming at the characteristic of tube-type bottle inspection,this paper proposed a new scheme for the whole tube·type bottle inspection system that included a diffusion illumination method in semi-dosed darkroom and a partial characteristic extraction methed through a parameter_made template．nle main contributions ofthis paper are as follows： Firgly，machine vision technology and glass bottle inspection technology were introduced，and a tube-type bottle vision inspection system Was designed by adopting PC， acquisition card camera and illumination system．11嵋design and realization of a diffusion illumination method in semi—closed darkroom was focused on in this paper． Secondly,after comparing some classic arithmetic in digital image processing，Winner Filter、OTSU and Canny edge detection Were chosen as the main arithmetic which had proved the efficiency and feasibility by lots ofexperiments． Thirdly,template matching and Hough Transform were adopted to compute the characteristic ofthe tube-type bottle，and error analy《s Was done． Finally,the GUI Was designed,including main window and different interface for different users． Key words：Machine vision；Image processing；Tube-type bottle inspection；Darkroom illumination；Templet matching 图l一1自动视觉检测系统 图l一1自动视觉检测系统图l一2抗生素管制瓶、安瓿瓶示例～一7图2--1系统框图一插图清单 ～一3．9 图2—2照明缺陷图a,b。c——一图2—3管制瓶检钡0光照实验平台曲——～一图2—4照明系统俯视图架构图2—5照明系统正面图架构——一——一14——．14————．13lO 图2--6 BL2850背光源和RLl360环形光源—— 15 图图2—8光源设计实验情景图——2--7镜头计算示意图 ————一～ ～20．23 图2—9管制瓶检测实验系统平台a,b,c，d——
