opencv开启前置摄像头拍照，与原有图片比较相似度
# coding:utf-8
import requests
from json import JSONDecoder
import cv2
compare_url = "https://api-cn.faceplusplus.com/facepp/v3/compare"
key = ""
secret = ""
faceId1 = "../1.jpg"
cap = cv2.VideoCapture(0)
ret, frame = cap.read()
cv2.imwrite("../3.jpg", frame)
faceId2 = "../3.jpg"
data = {"api_key": key, "api_secret": secret}
files = {"image_file1": open(faceId1, "rb"), "image_file2": open(faceId2, "rb")}
response = requests.post(compare_url, data=data, files=files)
req_con = response.content.decode('utf-8')
req_dict = JSONDecoder().decode(req_con)
confindence = req_dict.get('confidence')
print("相似度为：",confindence)
if confindence>=80:
print("数据比对成功，这两个人是同一个人,他们的相似度为%s"%confindence)
elif confindence>=70:
print("相似度为%s不确定是不是同一个人"%confindence)
else:
print("相似度为%s,两个人不是同一个人"%confindence)
