使用Python的名片扫描仪 GUI 应用程序

介绍

本项目是一个使用Python编写的名片扫描仪GUI应用程序，可以通过摄像头拍摄名片，识别名片信息并存储到本地或云端数据库中。该应用程序适用于需要快速录入名片信息的场景，如商务会议、招聘会等。

功能

• 拍摄名片并识别名片信息
• 将识别结果保存到本地或云端数据库中

技术栈

• Python
• OpenCV
• Tesseract OCR
• Tkinter GUI
• SQLite/MySQL

安装

1. 安装Python3
2. 安装以下Python库：OpenCV, Pillow, pytesseract, mysql-connector-python
3. 安装Tesseract OCR
4. 配置MySQL数据库（仅在使用MySQL时需要）

使用

1. 启动scanner.py文件，即可看到程序的GUI界面
2. 点击拍照按钮，使用摄像头拍摄名片照片
3. 点击识别按钮，程序会自动识别名片信息，并在界面上显示
4. 点击保存按钮，保存名片信息到本地或云端数据库中

import tkinter as tk
from PIL import Image, ImageTk
import pytesseract
import mysql.connector

# Capture video from camera
cap = cv2.VideoCapture(0)

# Load Tesseract OCR
pytesseract.pytesseract.tesseract_cmd = 'C:/Program Files/Tesseract-OCR/tesseract.exe'

# Connect to MySQL database
cnx = mysql.connector.connect(user='username', password='password',
                              host='127.0.0.1',
                              database='database_name')

# Initiate Tkinter GUI
root = tk.Tk()

# Create canvas to display video
canvas = tk.Canvas(root, width=640, height=480)
canvas.pack()

def capture():
    """Capture image from camera"""
    ret, frame = cap.read()
    cv2.imwrite("capture.jpg", frame)
    cv2.imshow("image", frame)

def recognize():
    """Recognize text from image"""
    image = cv2.imread("capture.jpg")
    gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
    text = pytesseract.image_to_string(gray)
    text_box.config(text=text)

def save():
    """Save text to database"""
    cursor = cnx.cursor()
    query = "INSERT INTO cards (name, company, email, phone) VALUES (%s, %s, %s, %s)"
    data = (name.get(), company.get(), email.get(), phone.get())
    cursor.execute(query, data)
    cnx.commit()

# Create buttons and textboxes
capture_button = tk.Button(root, text="Capture", command=capture)
recognize_button = tk.Button(root, text="Recognize", command=recognize)
save_button = tk.Button(root, text="Save", command=save)
name = tk.StringVar()
name_entry = tk.Entry(root, textvariable=name)
company = tk.StringVar()
company_entry = tk.Entry(root, textvariable=company)
email = tk.StringVar()
email_entry = tk.Entry(root, textvariable=email)
phone = tk.StringVar()
phone_entry = tk.Entry(root, textvariable=phone)
text_box = tk.Label(root, text="")
text_box.pack()

# Display buttons and textboxes
capture_button.pack()
recognize_button.pack()
save_button.pack()
name_entry.pack()
company_entry.pack()
email_entry.pack()
phone_entry.pack()

# Start main loop
root.mainloop()
