Two Correct Prices, Two Wrong Products: Building ShelfProof

Описание и применение

ShelfProof автоматически проверяет цены на рекламных материалах, сравнивая OCR‑вывод с утверждёнными данными SKU, выявляя ошибки и создавая отчёт для клиента.

Задача

Retail designers need to verify that printed prices match approved SKU data, but OCR errors and misplacement can cause mismatches.

Результат

ShelfProof detected three price differences, three matching readings, and one missing SKU in a sample proof, producing a 264 KB review file with embedded source crops.

Рабочий процесс

• Upload PDF/PNG/JPEG proof
• Upload approved sku,name,price CSV
• PDF.js renders page to pixels
• Tesseract.js OCR extracts words, confidence, bounding boxes
• Build review checklist from CSV
• Match OCR identifiers to approved SKUs
• Pair prices based on geometry and confidence
• Flag mismatches, low-confidence reads, missing SKUs
• Reviewer confirms or corrects associations
• Export self-contained HTML review with source crops

Доказательства

In ShelfProof’s fictional promotional artwork, SP-101 is approved at $8.50 and printed at $12.00. SP-102 has the reverse problem.

The checker is free. The paid offer I’m testing is a US$29 proof-review package: up to five pages, fifty SKUs, an issue sheet and one clarification round.

In the first real OCR run, Tesseract transcribed all six visible SKU labels and their prices correctly.
