人脸检测小程序是基于百度智能云人脸识别API接口实现的,操作简单,最重要的是免费,步骤如下:

一、获取人脸识别API的访问令牌

# 获取 access_token 数据
def token():
try:
# 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=ei2nro5Ugpzn11NkWpyoZGhm&client_secret=raEg24ORrOfBfhhaPRZ8swkUK5boWc1G’
response = requests.get(host).text
access_token = json.loads(response)[‘access_token’]
return access_token
except:
pass

二、读取图片数据,并转化为base64数据

# 读取图片二进制数据,并转换为base64数据
def base():
path = ‘img/img.jpg’
with open(path, ‘rb’)as f:
content = f.read()
image_b64 = base64.b64encode(content)
image = str(image_b64, ‘utf-8’)
return image

三、开始检测,筛选返回的参数信息

# 开始检测
def detection():
# 调用API
request_url = ‘https://aip.baidubce.com/rest/2.0/face/v3/detect’ + ‘?access_token=’ + token()
headers = {‘content-type’: ‘application/json’}
data = {
‘image’: base(),
‘image_type’: ‘BASE64’,
‘face_field’: ‘age,beauty,expression,face_shape,gender,glasses,landmark,landmark150,quality,eye_status,emotion,face_type,mask,spoofing’
}
# 爬取返回内容
responses = requests.post(request_url, data=data, headers=headers).text
responses_json = json.loads(responses)

# 获取返回信息
result = responses_json[‘result’]
lists = result[‘face_list’]

# 人脸类别
face_type = lists[0][‘face_type’]
if face_type[‘type’] == ‘human’:
print(‘类别:真实中的人\n’)
else:
print(‘类别:卡通中的人\n’)
# 性别
gender = lists[0][‘gender’]
if gender[‘type’] == ‘male’:
print(‘性别:男生\n’)
else:
print(‘性别:女生\n’)
# 年龄
age = lists[0][‘age’]
print(‘年龄:{} 岁\n’.format(age))

温馨提示

1、人脸识别更多参数查看API相关文档

2、需要导入的库requests,json,base64 ,其中 requests 为第三方库,需要安装pip install requests
