AI Technical Summary
Technical Problem
In the prior art, the detection effect of minor defects in blister capsules, such as deformation and pressing of bubbles, is poor.
Method used
By obtaining the color image of the medicine plate, extracting the medicine plate and capsule outlines, cropping the area where the capsule is located, retinex image enhancement and contrast enhancement, and finally judging the defect by comparing the non-defective area with the capsule outline.
Benefits of technology
It improves the detection efficiency of minor defects of blister capsules, ensures the quality of the packaging product and reduces production costs.

Abstract
The present invention relates to a blister capsule defect detection method and system, which obtains a color image of a medicine plate, then locates and extracts the contour of the color image to preliminarily determine whether the medicine has a large contour defect or missing grains. Then, the area where the capsule is located is cropped to obtain a rectangular image, and the rectangular image is enhanced based on the Retinex enhancement algorithm, and the contrast of the obtained first enhanced image is enhanced to facilitate the detection of non-defective areas. Finally, the non-defective area and the capsule contour are used to determine whether the blister or capsule at the corresponding position has defects. The present application performs defect detection on capsules in the blister, rather than single capsules before packaging, which ensures the quality of the packaged product. Compared with manual detection methods, the present invention improves detection efficiency and reduces the production cost of the enterprise.
