Pipeline de OCR para Documentos de Campo

En una frase

Turns decades of scanned reports, logs and maps into searchable text, including Persian and Arabic documents and handwritten annotations.

El problema

A typical operator holds tens of terabytes of scanned documents: daily reports, end-of-well reports, laboratory studies, correspondence, vendor reports. None of it is searchable, so the practical answer to any historical question is "we would have to go and look", which means the question is not asked.

Cómo funciona

A staged pipeline handles deskewing, denoising and layout analysis before recognition, with separate models for printed Latin, printed Persian and Arabic script, tables and handwriting. Persian and Arabic recognition is the hard part and is handled by models tuned on documents from this industry rather than by a general-purpose engine. Every page carries a per-region confidence score, and low-confidence pages are routed to human verification instead of being silently accepted.

Datos necesarios

  • The document archive in whatever state it exists, including mixed-quality scans and photographs of paper
  • Storage and compute on premise, sized to the archive
  • A sample set of representative documents for tuning, ideally several hundred pages
  • A naming or foldering convention if one exists, to seed metadata

Qué obtiene

  • Searchable text layer written back into the PDFs, with the originals untouched
  • Per-page confidence scores and a verification queue for low-confidence pages
  • Extraction-ready output feeding structured extraction and the retrieval index

Qué no puede hacer

Recognition accuracy on clean typed Persian text is high; on handwritten Persian in a remarks column it is much lower, and those regions are flagged rather than trusted. Blueprint-style drawings and well-log images are indexed as images with their text captions — the curves themselves are not digitised by this capability.
