【python 百度文字识别】通用文字识别（高精度版）

效果展现：

效果很是好~~~~

建立应用
首先你须要登陆百度AI,选择文字识别，建立一个应用，会生成 应用名称、AppID、API Key、Secret Key 这些东西，下面咱们代码是须要用到API_Key 和 Secret_Key 生成access_token。

python代码：

# encoding: utf-8
import time
import sys
reload(sys)
sys.setdefaultencoding('utf-8')
time1 = time.time()
import urllib, urllib2, base64
import json
import re

def get_token(API_Key,Secret_Key):
    # 获取access_token
    host = 'https://aip.baidubce.com/oauth/2.0/token?grant_type=client_credentials&client_id='+API_Key+'&client_secret='+Secret_Key
    request = urllib2.Request(host)
    request.add_header('Content-Type', 'application/json; charset=UTF-8')
    response = urllib2.urlopen(request)
    content = response.read()
    content_json=json.loads(content)
    access_token=content_json['access_token']
    return access_token


def recognition_word_high(filepath,filename,access_token):
    url='https://aip.baidubce.com/rest/2.0/ocr/v1/accurate_basic?access_token=' + access_token
    # 二进制方式打开图文件
    f = open(filepath + filename, 'rb')  # 二进制方式打开图文件
    # 参数image：图像base64编码
    img = base64.b64encode(f.read())
    params = {"image": img}
    params = urllib.urlencode(params)
    request = urllib2.Request(url, params)
    request.add_header('Content-Type', 'application/x-www-form-urlencoded')
    response = urllib2.urlopen(request)
    content = response.read()
    if (content):
        # print(content)
        world=re.findall('"words": "(.*?)"}',str(content),re.S)
        for each in world:
            print each



if __name__ == '__main__':
    API_Key = "****************************"
    Secret_Key = "*****************************"
    filepath = "E:/ID/"
    filename="59.jpg"
    access_token=get_token(API_Key,Secret_Key)
    recognition_word_high=recognition_word_high(filepath,filename,access_token)
