Abstract

The invention discloses a device and a method for detecting impurities after the filling of a beverage. After continuous frame images of a detection target are acquired through a video camera or a camera, the motion direction of a visible object existing in the images is analyzed by adopting the method which comprises the following steps of: partitioning a region; extracting connected domain structural information; acquiring a target motion trail through connected domain matching; and judging the property of the connected domain according to the obtained motion trail description of the connected domain and the structural characteristic of the connected domain so as to fulfill the aim of detecting the impurities after filling of the beverage. Due to the adoption of an image processing method, a visible object target can be partitioned and tracked well, manual detection can be fully replaced and cost is saved.

Description

technical field [0001] The invention relates to a device and method for detecting impurities after beverage filling. Background technique [0002] In the process of beverage filling and capping, due to poor filtration, dirty container cleaning, collision during packaging, etc., there will be solid precipitation, suspended matter, hair, glass fragments and other foreign matters in the beverage. The existence of these visible foreign matters is extremely Greatly affected product quality. At present, the method of manual light inspection is mostly used in China to identify visible foreign objects. Through human visual inspection, if there are foreign objects, they will be manually removed. Manual detection inevitably has problems such as low efficiency, high missed detection rate, and low precision. The light inspection also brings hazards to the health of the staff. [0003] Machine vision inspection technology has been successfully applied in many industries, such as empt...
