安装pytesseract 

pip install pytesseract 

pip install  Flask

安装语音包

sudo apt install tesseract-ocr-chi-sim

sudo apt install tesseract-ocr-eng

创建一个python文件ocr_server.py

from flask import Flask, request, jsonify
import pytesseract
from PIL import Image
import io

app = Flask(__name__)

# 设置 Tesseract 的路径
pytesseract.pytesseract.tesseract_cmd = r'/usr/bin/tesseract'

@app.route('/ocr', methods=['POST'])
def ocr():
    try:
        # 获取上传的图片文件
        file = request.files['image']
        if not file:
            return jsonify({'error': 'No image provided'}), 400

        # 读取图片文件
        image = Image.open(io.BytesIO(file.read()))

        # 进行 OCR 识别
        text = pytesseract.image_to_string(image, lang='chi_sim+eng')  # 同时使用简体中文和英文语言包

        # 返回识别结果
        return jsonify({'text': text})
    except Exception as e:
        return jsonify({'error': str(e)}), 500

if __name__ == '__main__':
    app.run(host='0.0.0.0', port=5003, debug=True)
