Bottled liquid foreign matter detection method and system

Abstract

The invention provides a bottled liquid foreign matter detection method and system. According to the method, the bottled liquid is inverted before entering the production line, two image acquisition devices are arranged on two different positions of the production line to perform imaging of the same area, and the abnormity of the acquired images is detected based on a sparse representation method.According to the technical scheme, the abnormity can be completely detected from the complex background so that the anti-noise performance is great and the method and the complex and high-interference environment of the actual production can be further facilitated. The used sequence image bottled liquid foreign matter detection based on sparse representation has high detection precision, great anti-noise performance and low requirement for the equipment so that the cost of the detection system can be reduced and the technical support can be provided for implementation of automation of bottledliquid foreign matter detection on the production line.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and system for detecting foreign matter in bottled liquid. Background technique [0002] In recent years, in order to meet the huge needs of consumers, the production industry of bottled liquid products such as beer, injections and beverages has developed steadily and rapidly. Only the adoption of new technology can improve product quality, reduce production costs and enhance the competitiveness of enterprises. With the modernization of production, the degree of automation of product production and packaging equipment is getting higher and higher. At present, manufacturers of bottled liquids use mechanical equipment to fill and automatically seal their products. Although this production method is efficient, it has certain disadvantages. During the automatic packaging process, the material of the bottle mouth and the precipitation of the filling container may be...
