2．关于理论方面的知识介绍

API介绍
图片翻译服务，基于文字识别与文本翻译技术，只需要通过调用图片翻译API，传入图片的地址，指定源语言与目标语言，通过POST请求方式，就可以识别图片中的文字并进行翻译。

3．调用有道API实现图片翻译实验

3.1官方代码与结果

# -*- coding: utf-8 -*-
import sys
import uuid
import requests
import base64
import hashlib

from imp import reload

reload(sys)

YOUDAO_URL = 'https://openapi.youdao.com/ocrtransapi'
APP_KEY = '*'                             # 应用ID
APP_SECRET = '*'          # 应用密钥


def truncate(q):
    if q is None:
        return None
    size = len(q)
return q if size <= 20 else q[0:10] + str(size) + q[size - 10:size]

def encrypt(signStr):
    hash_algorithm = hashlib.md5()
    hash_algorithm.update(signStr.encode('utf-8'))
return hash_algorithm.hexdigest()

def do_request(data):
    headers = {'Content-Type': 'application/x-www-form-urlencoded'}
return requests.post(YOUDAO_URL, data=data, headers=headers)

def connect():
    f = open(r'C:/Users/NO.1/Desktop/28.jpg', 'rb')  # 二进制方式打开图文件
    q = base64.b64encode(f.read()).decode('utf-8')  # 读取文件内容，转换为base64编码
f.close()

    data = {}
    data['from'] = 'en'                              # 图片源语言
    data['to'] = 'zh-CHS'   
    data['type'] = '1'
    data['q'] = q
    salt = str(uuid.uuid1())
    signStr = APP_KEY + q + salt + APP_SECRET
    sign = encrypt(signStr)
    data['appKey'] = APP_KEY
    data['salt'] = salt
data['sign'] = sign

    response = do_request(data)
    results = response.content

print(results)

if __name__ == '__main__':
    connect()

实验结果

存在问题：图片中的英文成功识别，但是转换成中文后未进行解码

3.2解码

    data = {}
    data['from'] = 'en'                              # 图片源语言
    data['to'] = 'zh-CHS'   
    data['type'] = '1'
    data['q'] = q
    salt = str(uuid.uuid1())
    signStr = APP_KEY + q + salt + APP_SECRET
    sign = encrypt(signStr)
    data['appKey'] = APP_KEY
    data['salt'] = salt
    data['sign'] = sign

    response = do_request(data)
    results = response.content.decode()

print(results)

if __name__ == '__main__':
    connect()

实验结果

存在问题：可以成功将图片中的英文转换成中文，但是结果太过凌乱，影响读者观看，所以对结果再次处理
