Owing to the difference in physical and chemical properties, the liquid drops' growth states are dissimilar to different liquids under same conditions. And this drop growth difference to various liquids is embodied in the corresponding drop's contour feature obviously. Thus the liquid identification method based on CCD imaging system will be introduced in detail in this paper. Through experiments to different liquids, the region area, boundary girth, drop length, drop plumpness, drop circularity, and the profile edge of the liquid drop image will be extracted and analyzed. And with these information the liquid identification can be realized. From sample experiments the region area and the drop plumpness is more effective than other parameters in liquid discrimination. And the boundary girth and drop length difference is very small to some liquids, thus they are the realitive weaker character to liquid drops.
