Detecting method of beer foam compensating liquid level

Abstract

The invention discloses a detecting method of beer foam compensating liquid level. The method comprises the steps of scanning a liquid level from bottom to top so as to find the position of a liquid level line, conducting binarization processing on an image by a control center, calculating the black pixel of the foam from upside of the liquid level line to a region of a bottle opening, calculating the height value of the foam, and calculating the value of the foam compensating liquid level according to a set weight. According to the method, the process is reasonable, the method is reliable, and whether the liquid level is qualified or not can be judged accurately.

Description

technical field [0001] The invention belongs to the technical field of machine vision detection, and in particular relates to a detection method for beer foam compensation liquid level. Background technique [0002] As the automation level of industrial production is getting higher and higher, beer filling has also realized fully automatic assembly line operations, including the processes of bottle washing, filling, sterilization, labeling and packing. In the whole process of beer packaging, the inspection is divided into two parts, one part is the inspection of empty bottles, including whether the cleaning is clean, etc., and the other part is the inspection of the finished beer after filling and capping. On the beer filling production line, due to the long-term operation of the filling machine, there are often phenomena such as filling blockage or insufficient filling pressure, resulting in some half-bottles of beer being filled and capped. Due to the characteristics of e...

Problems solved by technology

And on the production line, after the beer is filled by the filling machine, there will be a lot of foam. If the beer filling level is detected at this time, a large amount of foam will reduce the accuracy of the detection. no longer applicable
