Mac-OCR-CLI

MAC-OCR-CLI is a powerful command-line interface tool for Optical Character Recognition (OCR) on macOS.

It leverages FastAPI, ocrmac, and Typer to provide a seamless OCR experience directly from your terminal or through a local API server.

Features

• Easy-to-use CLI for starting an OCR server
• RESTful API endpoint for OCR tasks
• Built on FastAPI for high performance
• Utilizes ocrmac for accurate OCR on macOS
• Supports base64 encoded image input
• Intelligent text merging by line
• Beautiful console output using Rich library
• Customizable server settings (port, host, log level)

Requirements

• Python 3.6+
• macOS (due to ocrmac dependency)
• pip (Python package installer)

Installation

1. Ensure you have Python 3.6+ installed on your macOS system.

2. Install MAC-OCR-CLI using pip:

   pip install mac-ocr-cli
   

Usage

Starting the OCR CLI

mac-ocr file <your_image_path>

Starting the OCR Server

To start the OCR server with default settings:

mac-ocr server

You can customize the server settings using command-line options:

mac-ocr server --port 8080 --host 127.0.0.1 --log-level debug

Available options:

• --port or -p: Set the server port (default: 8000)
• --host or -h: Set the server host (default: 0.0.0.0)
• --log-level or -l: Set the log level (default: info)
• --token or -t: Set the token (default: None)

Performing OCR

Once the server is running, you can perform OCR on an image using a POST request to the /ocr endpoint:

curl --location 'http://127.0.0.1:8080/ocr' \
--header 'Authorization: 123456' \
--header 'Content-Type: application/json' \
--data '{
    "image_path":"<your_image_path>"
}'

Replace your_image_path with your actual image path.

curl --location 'http://127.0.0.1:8080/ocr' \
--header 'Authorization: 123456' \
--header 'Content-Type: application/json' \
--data '{
    "image_base64":"<base64_encoded_image_data>"
}'

Replace <base64_encoded_image_data> with your actual base64-encoded image data.

The server will respond with the OCR results in JSON format:

{
    "code": 200,
    "message": "success",
    "data": {
        "annotations": [
            [

        "fullText": [
            "INTP女",
            "为什么罕见"
        ]
    }
}

Note: The OCR results are returned in reverse order (bottom to top) of the original image.
