In the process of wine brewing, there are many factors that affect the product quality, such as the quality of raw materials, technology, brewing technology, etc. in addition, bottle defects (bottle day, bottle body and bottle bottom) and dirt are also a key factor affecting the quality of wine. Therefore, the empty glass bottle must be tested before the wine filling, and the unqualified products can be removed before the wine can be filled. At present, most wineries in China still use manual inspection of the quality of empty glass bottles, which is inefficient, slow and labor-intensive. Machine vision is very suitable for the measurement, inspection and identification in the process of mass production. The application of linear CCD in continuous and scanning online measurement has great advantages. Using machine vision inspection method can greatly improve the degree of automation of production, and machine vision is easy to realize information integration, which can greatly improve product quality and production efficiency.
