Device and method for automatically detecting foreign matters in white spirit bottle based on vision

Abstract

The invention discloses a device and a method for automatically detecting foreign matters in a white spirit bottle based on the vision. The method comprises the steps of enabling liquid in the white spirit bottle to rotate at high speed by rotating a bottle body, enabling the foreign matters in the liquid to still rotate at high speed on the premise that the liquid in the bottle is basically stable by virtue of emergency stop, carrying out image acquisition and analysis on the liquid in the bottle under the situation, and detecting the foreign matters of the liquid in the bottle; setting multiple exposure parameters of an industrial camera, and obtaining multiple images under various exposure times, so that the influence of the absorption non-uniformity of light source on the image quality caused by the refraction and the non-uniformity of the paint of the bottle bottom can be alleviated. The device and the method can be suitable for detecting the foreign matters in various non-transparent bottles and various engraved transparent specially-shaped bottles of the white spirit, has the advantages of high detection sensitivity, low error rate and high detection speed, can completely substitute the existing eye detection and can fill in the gap of the automatic white spirit detection industry.

Description

technical field [0001] The invention relates to the technical field of automatic detection of foreign objects in liquor bottles, in particular to a vision-based automatic detection device and method for foreign objects in liquor bottles. Background technique [0002] At present, the liquor bottles on the market are basically opaque bottles and transparent special-shaped bottles. The opaque bottles mainly include glass spray bottles and porcelain bottles, and the transparent special-shaped bottles include glass transparent bottles with various shapes and some with various engravings. Liquor adopts these bottle shapes with different shapes. The advantage is that various effect patterns can be made on the bottle body to increase the aesthetic effect and improve the grade of liquor. The disadvantage is that it brings great trouble to the detection of foreign objects in the bottle after filling. The foreign matter in liquor includes tiny insoluble foreign matter such as glass sha...
