Dynamic OCR inspection with HALCON ensures most product quality

Production processes in the pharmaceutical industry are field to specifically strict factual rules. In line with Good Manufacturing Discover (GMP), merchandise have to easy be manufactured to consistently top quality standards

Resulting from strict compliance rules, packaging for medical merchandise have to easy be precisely labeled sooner than it is a ways dropped at prospects. For this goal the Chinese company Shenzhen Jiangrun Xuneng Technology has developed a sophisticated machine imaginative and prescient solution that robotically reads personality codes the utilization of OCR. The heart of the appliance is the everyday machine imaginative and prescient instrument MVTec HALCON. This enables the shopper to develop the efficiency of the inspection processes and tremendously enhance product quality.

Production processes in the pharmaceutical industry are field to specifically strict factual rules. In line with Good Manufacturing Discover (GMP), merchandise have to easy be manufactured to consistently top quality standards. Accordingly, the pointers impose strict requirements on the documentation of workflows and the inspection of items. Standard exams are intended to make certain most security and efficacy of the merchandise.

The worldwide neatly being and meals company H&H Community is additionally straight away tormented by GMP: in picture to reliably regulate to the rules, the manufacturer have to precisely imprint the packaging of its medical and cosmetic merchandise. For this goal, varied details equivalent to batch number, date of create, and expiration date are printed on the cartons. The personality combos have to easy be correct and full. Here’s the most consuming capacity to make certain that merchandise would possibly well perchance be precisely known and that quality requirements shut to labeling are consistently met. It is miles ensuing from this fact a have to have to overview the personality codes pretty sooner than the cartons leave the manufacturing facility and are introduced to prospects.

Inadequate controls resulted in complaints

Till now, this regulate job at the H&H Community was utilized purely manually, which proved to be very costly and time-absorbing. Resulting from the excessive number of functions and the hasty cycle payment, inspection would possibly well perchance also in general only be utilized on a random basis. In some instances, this resulted in incorrectly labeled merchandise being introduced to wholesalers and other prospects. Which capacity, complaints and grievances piled up, main to financial losses, customer losses, and serious hurt to the corporate’s image.

In picture to enhance the everyday of product labeling, the inspection job needed to be made more ambiance friendly. To this stop, the managers at the H&H Community commissioned Shenzhen Jiangrun Xuneng Technology to make an acceptable solution. The company makes a speciality of 2D and AI instrument frameworks that focus primarily on 2D and 3D imaginative and prescient choices, together with localization, identification, and dimension of objects. The provider makes a speciality of a huge number of industries, equivalent to meals, medication, chemical substances, packaging, automotive, and rail transport.

Machine imaginative and prescient platform automates visible inspection

Shenzhen Jiangrun Xuneng Technology has developed a machine imaginative and prescient platform that allows the visible inspection of product labels on packaging to be fully automatic. The letter-number combos are learn and checked the utilization of in vogue optical personality recognition (OCR) technologies. “This application offered us with major challenges. The characters printed on the cartons are in general encrypted, with a kind of forms and sizes of codes mixed. The characters are in general now not located precisely where they needs to be, nonetheless are offset. In addition, the letters and numbers are in general printed incorrectly, unclearly, or blurred on the packaging, which is ready to result in issues in clearly recognizing the codes,” explains King Wang technical application engineer at Jiangrun.

Any other venture is the hasty cycle payment of the inspection workflow. The characters have to easy be learn and checked at excessive inch in picture to operate most product throughput. This requires comprehensive preprocessing by the OCR algorithms. Here’s the most consuming capacity to reliably bag the respective goal level, ensuring the supreme doubtless recognition accuracy even with a kind of forms and sizes of characters.

MVTec HALCON ensures staunch identification and localization of characters

Jiangrun’s machine imaginative and prescient platform permits these complex requirements to be addressed with precision. The everyday machine imaginative and prescient instrument merchandise MVTec HALCON, which compose the guts of the answer, are passe for this goal. The HALCON algorithms are passe for pre- and post-processing of the photos as neatly as for the actual identification and localization of characters. The instrument have to first precisely acknowledge the personality background in the image and bag a horizontal reference line to resolve the actual space of the characters. Within the job, a negate of ardour (ROI) is printed within which the numbers and letters, equivalent to an expiration date or batch designation, are known, learn, and checked. By comparing them with reference characters, errors in the labeling would possibly well perchance be reliably detected.

Dynamic OCR with excessive balance and inch

“Thanks to MVTec HALCON, we had been ready to tremendously shorten the mission cycle, decrease the prices for pattern, operation, and repairs of our machine imaginative and prescient platform, and tremendously enhance the efficiency of implementation. In addition, we’re ready to place into effect dynamic optical personality recognition with excessive balance and processing inch. Fresh sorts of merchandise, markings, or fonts can additionally be flexibly added to the appliance. This enables us to optimize OCR inspection, duvet a huge number of a kind of personality specs, and operate correct results even with uncover errors or incorrectly positioned characters,” says King Wang.

The stop customer additionally benefits from the machine imaginative and prescient platform powered by MVTec HALCON: The H&H Community can automate the total inspection job and serve its workers of behind manual work. This improves the efficiency of inspection workflows and maintains the everyday of product labels at a consistently excessive stage. Which capacity, the number of client complaints is diminished to a minimum and the emblem’s image is tremendously enhanced.

Further functions with MVTec HALCON are planned

In line with the a hit collaboration, Jiangrun plans to place into effect further image processing functions with MVTec HALCON in the future: “We beget got a spread of standard instrument frameworks that exercise HALCON to place into effect machine imaginative and prescient functions. This enables us to love complex image processing projects for our prospects remarkable more with out issues and successfully. I’d settle on to mention the intensive exchange with our MVTec colleagues in China. Their professionalism, technical suggestion, and practising helped us to place into effect the mission hasty,” concludes King Wang.
