OCR Character Recognition Vision System
HKDesk OCR Vision System reads and verifies printed batch numbers, manufacturing dates, expiry dates, serial codes, and prices on pharmaceutical cartons, bottles, ampoules, and flexible packaging. Results depend on validated optics, lighting, print quality, and recipe settings.
OCR Inspection Capabilities
Configurable OCR Backends
Supports font-based string reading and OCR processing with configurable character whitelists and recipe-specific recognition settings.
Multi-Field Match & Verification
Verifies Batch No., Mfg Date, Exp Date, MRP, and Serial Numbers against expected values or imported database lists.
Recipe-Configurable Acceptance Scores
Configurable string acceptance, character similarity, and character homogeneity threshold parameters.
Image Preprocessing & Masking
Includes image thresholding, inversion, rotation, eraser masking regions, and dynamic contrast filters.
PLC Line Control & Rejection
Triggers PLC rejection valve with pre-rejection count, ON/OFF delays, and automated conveyor stop on fail.
Role-Based Audit & Event Logging
Records configured user, batch, inspection, and failure events, with failed-image storage for review and reporting.

OCR Vision System FAQs
How does the software handle faint or smudged characters?
Thresholding, inversion, masking, and contrast controls can improve difficult images. Acceptance still depends on print and image quality, so every recipe should be validated with representative production samples.
Can expected batch numbers be matched against an external database or Excel list?
The configurable data-profile workflow supports fixed expected values, SQL-backed validation, and approved Excel imports, depending on the project setup.
Does it log inspection failures and audit events?
The application records configured inspection results, batch and user events, and failed images in CoreDB and AuditDB structures for review and reporting.
