PaddleOCR ONNX Models

🔥 ONNX format models converted from PaddleOCR for easy deployment and testing

📖 Model Description

This repository contains ONNX format models converted from PaddleOCR, a practical ultra-lightweight OCR system. These models are optimized for production deployment and cross-platform compatibility.

📦 Model Files

File Name	Size	Description
`PP-OCRv5_server_det_infer.onnx`	84MB	Text detection model - locates text regions in images
`PP-OCRv5_server_rec_infer.onnx`	81MB	Text recognition model - recognizes text content
`UVDoc_infer.onnx`	30MB	Document rectification model - corrects document perspective
`PP-LCNet_x1_0_doc_ori_infer.onnx`	6.5MB	Document orientation detection
`PP-LCNet_x1_0_textline_ori_infer.onnx`	6.5MB	Text line orientation detection
`PP-OCRv5_server_rec_infer.yml`	145KB	Recognition model configuration file

Total Size: ~208MB

🚀 Quick Start

Installation

bash

pip install huggingface_hub onnxruntime

Basic Usage

python

import onnxruntime as ort
import numpy as np
from PIL import Image

# Load detection model
det_session = ort.InferenceSession("models/PP-OCRv5_server_det_infer.onnx")

# Load recognition model  
rec_session = ort.InferenceSession("models/PP-OCRv5_server_rec_infer.onnx")

# Your OCR pipeline implementation here...

🔧 Technical Details

Conversion Process

These models were converted from PaddlePaddle format to ONNX format for broader compatibility:

1.Source: Original PaddleOCR models from PaddlePaddle Hub
2.Conversion: PaddlePaddle → ONNX format
3.Optimization: Model optimization for inference speed
4.Validation: Output consistency verification

System Requirements

—Runtime: ONNX Runtime
—Python: 3.7+
—Memory: Minimum 2GB RAM recommended
—Platform: Cross-platform (Windows, Linux, macOS)
