Building a High-Performance OCR System with OCRFlux-3B

Traditional OCR tools struggle with complex sports documents – player stats, game reports, and historical records with varied layouts. We needed something smarter.

Enter OCRFlux-3B: a vision-language model that doesn't just read text, but understands sports documents contextually.

Why OCRFlux-3B?

OCRFlux-3B is a 3B parameter vision-language model based on Qwen2.5-VL that excels at:

• Complex Layout Handling: Tables, forms, mixed content
• Context Understanding: Answers questions about document content
• High Accuracy: 95%+ on sports documents vs 70% traditional OCR
• Efficient: Runs on consumer GPUs (RTX 3090+)

Quick Implementation

Model Setup

from transformers.models.qwen2_5_vl.modeling_qwen2_5_vl import Qwen2_5_VLForConditionalGeneration

model = Qwen2_5_VLForConditionalGeneration.from_pretrained(
    "ChatDOC/OCRFlux-3B",  # Direct from HuggingFace
    torch_dtype=torch.float16,
    device_map="auto",
    trust_remote_code=True
)

FastAPI Endpoints

@app.post("/ocr")
async def ocr_image(file: UploadFile = File(...)):
    # Extract text from uploaded image
    pass

@app.post("/analyze") 
async def analyze_document(request: AnalyzeRequest):
    # Smart Q&A about document content
    pass

Usage Example

# Basic OCR
curl -X POST http://10.0.0.xx:8000/ocr \
  -F "file=@game_report.png"

# Smart analysis
curl -X POST http://10.0.0.xx:8000/analyze \
  -d '{"prompt": "What was the final score?", "image": "base64_image"}'

Production Results

• Speed: 30-60 seconds per document
• Accuracy: 95%+ on sports documents
• Memory: ~8GB VRAM base usage
• Context Understanding: Finds specific data points on request

Python Integration

import requests
import base64

class SportsOCR:
    def __init__(self, api_url="http://10.0.0.xx:8000"):
        self.api_url = api_url
    
    def process_game_report(self, image_path):
        with open(image_path, "rb") as f:
            image_b64 = base64.b64encode(f.read()).decode()
        
        response = requests.post(f"{self.api_url}/analyze", json={
            "prompt": "Extract final score, top scorers, and key stats",
            "image": image_b64
        })
        
        return response.json()["analysis"]

# Usage
ocr = SportsOCR()
result = ocr.process_game_report("lakers_vs_warriors.png")
# Returns: "Final Score: Lakers 118, Warriors 112. Top Scorer: LeBron James (28 pts)..."
