使用腾讯云OCR识别图片-英语版

今天因为网课需要（实则自己懒）需要使用图片转文字，于是一开始博主准备用百度云，但是因为通用印刷没有英文标示，于是换到了腾讯云（API生成器好评），腾讯云给的额度没有百度云的高，但是也够用，1千次一个月的英文图片调用量。

这次用的是python，首先的准备工作是，以此为例

pip install tencentcloud-sdk-python

下载我们腾讯的py-sdk。然后使用我们的

API Explorer

然后生成出一段调用API接口的代码（博主用的HTTP调用）

# -*- coding = utf-8 -*-
from tencentcloud.common import credential
from tencentcloud.common.profile.client_profile import ClientProfile
from tencentcloud.common.profile.http_profile import HttpProfile
from tencentcloud.common.exception.tencent_cloud_sdk_exception import TencentCloudSDKException 
from tencentcloud.ocr.v20181119 import ocr_client, models 
try: 
    cred = credential.Credential("SecretId", "SecretKey") 
    httpProfile = HttpProfile()
    httpProfile.endpoint = "ocr.tencentcloudapi.com"

    clientProfile = ClientProfile()
    clientProfile.httpProfile = httpProfile
    client = ocr_client.OcrClient(cred, "ap-shanghai", clientProfile) 

    req = models.EnglishOCRRequest()
    params = '{"ImageUrl":"图床地址"}'
    req.from_json_string(params)

    resp = client.EnglishOCR(req) 
    print(resp.to_json_string()) 

except TencentCloudSDKException as err: 
    print(err) 

这样我们就获取到了json返回的图片解析。可以看到返回的内容在DetectedText上

但是如果在控制台上就是另一番风景，这个怎么看嘛，没法看，那有什么办法直接提取出来么，当然肯定有啦。用标准库里的json以及json.loads函数，废话不多说直接上代码

# -*- coding = utf-8 -*-
from tencentcloud.common import credential
from tencentcloud.common.profile.client_profile import ClientProfile
from tencentcloud.common.profile.http_profile import HttpProfile
from tencentcloud.common.exception.tencent_cloud_sdk_exception import TencentCloudSDKException 
from tencentcloud.ocr.v20181119 import ocr_client, models 
import json
try: 
    cred = credential.Credential("ID", "KEY") 
    httpProfile = HttpProfile()
    httpProfile.endpoint = "ocr.tencentcloudapi.com"

    clientProfile = ClientProfile()
    clientProfile.httpProfile = httpProfile
    client = ocr_client.OcrClient(cred, "ap-shanghai", clientProfile) 

    req = models.EnglishOCRRequest()
    params = '{"ImageUrl":"图片地址"}'
    req.from_json_string(params)

    resp = client.EnglishOCR(req) 
    #print(resp.to_json_string()) 
    t = json.loads(resp.to_json_string())
    #print(type(t))
    for item in t["TextDetections"]:
        print(item["DetectedText"])

except TencentCloudSDKException as err: 
    print(err)

这样我们就搞定了控制台里输出的混乱问题。
