Rebuilding Vision Recognition with Tesseract OCR & 8 Threads

AI Baccarat Vision System · Client Engagement (Doway Digital Delivery)
PROBLEM & CONSTRAINT

A prior contractor failed with YOLO, leaving an unusable prototype. In production with 8 concurrent tables, sequential single-threaded inference intermittently breached betting cutoff countdowns.

ARCHITECTURAL DECISION

Recognizing the target was strictly numerical fonts, pivoted to lightweight Tesseract OCR from scratch. Restructured pipeline with 8 dedicated worker threads, thread-local state isolation, and a shared thread-safe action queue.

VERIFIED IMPACT

Rebuilt and shipped within 1 week, eliminating concurrent table latency and running reliably in client production.

VERIFIED: Shipped from scratch in 1 week · Zero latency across 8 tables
