Abstract

The invention discloses a cod liver oil soft capsule appearance defect visual detection method and a detection device thereof. The method consists of: shooting horizontally transferred bubble caps line by line with a camera tilting downward to obtain shot pictures; calling bubble cap templates matching the shot pictures to obtain the inner slot positions of the bubble caps; acquiring the regional images of the inner slot positions corresponding to the shot pictures, extracting a soft capsule outer contour from the regional images by gray threshold segmentation, and judging whether particle deficiency exists accordingly, and if so, sending out appearance defect information; matching the regional images with the cod liver oil soft capsule shape to separate and extract a fish body regional image and a fish tail regional image; and respectively calculating the image features of the fish body regional image and the fish tail regional image, and judging whether abnormity or empty shell exists accordingly, and if so, sending out appearance defect information. The detection method provided by the invention not only can rapidly and accurately detect the defects of multiple particles and particle deficiency in cod liver oil soft capsules within bubble caps, but also can detect a variety of other appearance defects in cod liver oil soft capsules.

Description

technical field [0001] The invention relates to a method for visually detecting appearance defects of cod liver oil soft capsules and a device thereof. Background technique [0002] Cod liver oil is fat extracted from the liver of sharks, cod, etc. It is yellow and translucent. Cod liver oil soft capsules are similar to fish in shape and irregular; the capsules are thin and easy to break, and the oil is easy to flow out. Translucent cod liver oil softgels are also prone to sticking to dust and impurities. Therefore the cod liver oil soft capsule of production must carry out strict detection. The traditional appearance defect detection of cod liver oil soft capsules is done manually, which not only has low efficiency but also low accuracy. At the same time, the standards of different testers will be different, which will make the quality of the detected cod liver oil soft capsules uneven. [0003] In response to the above deficiencies, someone proposed a machine vision-ba...
