The whole article is divided into the following parts:
Table of contents
1. Enter Baidu AI open platform to create animal recognition applications
2. Use code to obtain access_token
3. Realize the function of animal recognition
4. Animal picture recognition UI_demo
1. Enter Baidu AI open platform to create animal recognition applications
Connection: Animal Recognition_Photo Recognition of Animals-Baidu AI Open Platform
The steps after logging in are as follows:
After the creation is completed, it will look like this:
The API Key and Secret Key here are what you need to use later.
2. Use code to obtain access_token
To call the API, you must first obtain the access_token, which is obtained through the API Key and Secret Key.
The implementation code is as follows:
import requests
# client_id 为官网获取的AK， client_secret 为官网获取的SK
host = 'https://aip.baidubce.com/oauth/2.0/token?grant_type=client_credentials&client_id=【此处填API Key】&client_secret=【此处填Secret Key】'
response = requests.get(host)
if response:
print(response.json())The value of access_token can be found in the results after running
Record the value of access_token
3. Realize the function of animal recognition
code show as below:
request_url = "https://aip.baidubce.com/rest/2.0/image-classify/v1/animal"
# 二进制方式打开图片文件
f = open('test7.png', 'rb') #这里是你的图片路径
img = base64.b64encode(f.read())
f.close()
params = {"image":img,"top_num": 3} #返回前3个概率比较大的
access_token = '这里放access_token的值'
request_url = request_url + "?access_token=" + access_token
headers = {'content-type': 'application/x-www-form-urlencoded'}
response = requests.post(request_url, data=params, headers=headers)
if response:
print (response.json())operation result:
This enables the call of Baidu AI animal image recognition API.
