Optical Character Recognition (OCR)

What Is Optical Character Recognition (OCR)?

Optical Character Recognition (OCR) is a technology that identifies and digitizes printed or handwritten text within images, scanned documents, or real-world environments. It combines computer vision and pattern recognition to analyze pixel data, detect characters, and convert them into standardized digital text. Unlike basic text scanning, OCR interprets complex layouts, fonts, and languages while preserving structural elements like tables or columns.

Analyze Your Use Case

NYRIS embeds OCR into its visual search solutions to enable instant text extraction from technical manuals, product labels, and industrial equipment. This capability allows manufacturers to quickly identify spare parts using serial numbers or specifications, reducing machine downtime by up to 65%.

How Optical Character Recognition (OCR) Works

NYRIS’s OCR pipeline follows a four-stage process optimized for industrial applications:

  1. Image Acquisition and Preprocessing: The system captures high-resolution images via cameras or scanners, then enhances quality by adjusting contrast, removing noise, and correcting skew. For low-light industrial environments, NYRIS employs synthetic data techniques to simulate optimal lighting conditions.
  2. Text Detection and Segmentation: Deep learning models isolate text regions from backgrounds, even in cluttered settings like factory floors. NYRIS’s algorithms excel at detecting distorted or partially obscured text, such as worn labels on machinery.
  3. Character Recognition and Validation: A convolutional neural network (CNN) classifies individual characters, cross-referencing results against industry-specific lexicons (e.g., technical terms or part numbers). NYRIS’s custom dictionaries improve accuracy for specialized domains like automotive or aerospace.
  4. Structured Output Generation: Extracted text is formatted into JSON or XML, integrating with enterprise systems like SAP for real-time updates to inventory databases or maintenance schedules.

Industrial Applications

Manufacturing

  • Spare Parts Identification: OCR extracts part numbers from equipment manuals or labels, enabling technicians to locate replacements in under 1 second via NYRIS’s visual search engine. Partner DMG Mori reduced downtime by 72% using this solution.
  • Quality Control: Automatically verify labels on production lines, ensuring compliance with regulatory standards.

E-commerce

  • Product Cataloging: Convert packaging text into searchable metadata, improving product discoverability. IKEA uses NYRIS’s OCR to tag over 500 million products with attributes like dimensions and materials.
  • Receipt Processing: Extract purchase details from customer receipts for automated returns or loyalty programs.

Retail

  • Inventory Management: Scan shelf labels to track stock levels in real time. METRO achieved 98% inventory accuracy using NYRIS-powered handheld scanners.
  • Multilingual Support: Recognize text in 50+ languages, facilitating global operations for brands like Renault.

FAQs

Can OCR handle handwritten text?

Yes. NYRIS trains models on diverse handwriting samples, including those from manufacturing checklists or retail inventory sheets. Accuracy reaches 94% for printed text and 82% for handwriting in controlled environments.

How does NYRIS’s OCR differ from generic solutions?

NYRIS tailors OCR models to industry-specific challenges, such as reading embossed text on metal parts or handwritten notes in maintenance logs. The system integrates with SAP ERP to trigger automated workflows, like reordering parts when stock reaches critical levels.
