Liquid surface location of transparent container based on visual analysis

This paper presents a new method of liquid surface location based on visual analysis, which was proposed with the visual navigation of imagery processing technology. Firstly, hospital medical infusion bottle image was binarized by the statistical methods of energy. Secondly, binary image was carried on the image segmentation through the projection statistics method and the Shen algorithm. Finally, horizontal projection image is smoothed by Shen algorithm. The experimental results show that the proposed method can accurately locate and real-time tracking of medical infusion bottle surface.
