偏心口检测与自动定位系统的研究

针对国内外罐装技术的发展现状以及长期从事该工作的人员会受到身体伤害，提出了基于机器视觉技术的剧毒液体自动灌装机桶口自定位技术。系统利用CCD传感器技术，图像采集与传输技术，快速采集灌装桶图像，传输到计算机中，然后利用图像边缘检测技术，把灌装桶盖表面图像与背景分离，提取出桶盖表面图像，进一步采用Hough变换，对提取出的桶盖表面图像处理，计算出加注口的位置，经过坐标变换，将加注口的位置坐标从图像像素逻辑坐标转换到空间坐标。最后利用步进驱动系统与机械传动系统将注油枪带动到加注口上方，实现自动定位。

Research on Detection and Automatically Orientation of Eccentric

Now the technology of automatically irrigate liquid can stir make the worker damaged.To resolve the problem,the article adopts machinery vision technology to get the position of the bunghole.It used some tech- nology such as CCD,image collection and image transmitting technology.First,it gets the image of the barrel- head and transmits it to computer.Second,it separates the image and backgrounds by image brim detect tech- nology and computes the information of the eccentric by Hough transformation.Third,it transits the image pixel logistic coordinate to space coordinate.Finally,it drives the oiling gun to the position of the bunghole.
