On-line automatic detection method and on-line automatic detection system for foreign matters in transparent bottled liquid products

Abstract

The invention discloses an on-line automatic detection method and an on-line automatic detection system for foreign matters in transparent bottled liquid products, which belong to the technical fieldof the detection of foreign matters in bottled liquid products. According to the on-line automatic detection method for the foreign matters in the transparent bottled liquid products disclosed by theinvention, as bottles are conveyed on line along a conveyer line, the bottles are rolled over, and as the bottles are rolled over, the image information of the bottles is acquired; image processing iscarried out for the image information, and whether the foreign matters exist in the bottles is then judged. The automatic detection system comprises a conveyer line, a rollover mechanism, an image acquisition device, and an image processing system. By arranging the rollover mechanism, a rollover function can be carried out as bottles are conveyed on line along the conveyer line, and thereby the images of the bottles are acquired in the process of rollover in order to detect the foreign matters in the bottles.

Description

technical field [0001] The invention relates to the technical field of detection of foreign objects in bottled liquid products, in particular to an online automatic detection method and detection system for foreign objects in transparent bottled liquid products. Background technique [0002] In the production process of bottled products, such as bottled wine products, foreign matter detection is generally required to ensure that there are no foreign matter in the product during the production process. At present, the detection of foreign matter in transparent bottled liquid products is divided into manual detection and automatic detection; among them, automatic detection is mainly divided into static detection and dynamic tracking detection; both static detection and dynamic tracking detection need to collect corresponding image information, and then After the image information is processed by the corresponding algorithm, it is judged whether there is a foreign object in the...

Problems solved by technology

[0004] In addition, according to the different positions of foreign objects detected in the bottle, foreign object detection is usually divided into floating object detection, suspended object detection and deposited foreign object detection; and the detection of foreign objects in different positions is currently difficult to use due to differences in imaging effects A single detection method detects foreign matter in different positions inside the bottle

[0005] In addition, in the existing automatic detection process, due to the limitation of the attitude of the bottle body during the conveying process, usually the bottle body is conveyed along the conveying line in a vertical posture position during the conveying process, that is, the head of the bottle body On the top and bottom on the bottom, the axis of the bottle is conveyed in a vertical state; the image acquisition direction of the detection bottle is mainly from the horizontal direction or the side direction inclined up and down, so it is generally difficult to acquire images of the liquid surface , making it difficult to detect floating objects on the liquid surface

[0006] In addition, since the head and bottom of the bottle product are usually uneven or irregular in structure, the imaging image will be greatly distorted when the image is collected from the head, bottom or side of the bottle. , which is not conducive to image processing and effective detection of foreign matter; especially for foreign matter deposited at the bottom of the bottle, usually only dynamic tracking detection method can be used for detection
