face++与python实现人脸识别签到（考勤）功能

项目实现利用face++开发一个课堂签到的软件，实现面向摄像头即可完成记录学号、姓名和时间的签到工作。

代码：

流程代码，主文件

#!usr/bin/
# -*- coding: utf-8 -*-
import requests
from json import JSONDecoder
import csv
import cv2
import time
import tkinter as tk

search_url = "https://api-cn.faceplusplus.com/facepp/v3/search"

cv2.destroyAllWindows()

print("waiting...")

faces_token = req_dict["face_tokens"]
print("...")

if pre_face_token in faces_token and pre_confidence >= pre_thresholds:
 labaltext = faceID_dict[pre_face_token] + "\n\n\n" +str(time.asctime(time.localtime()))

建立云脸数据集的模块：

#!usr/bin/
# -*- coding: utf-8 -*-
import requests
import time
from json import JSONDecoder
import csv

http_url ='https://api-cn.faceplusplus.com/facepp/v3/faceset/addface'
key = "z_qkMMqK1efq8ikgAPOEn89A7And-lAa"
secret = "***********************"
faceset_token = '******************************'

face_tokens_str = ''
csvfile = open('face_token.csv','r')
freader = csv.reader(csvfile)
facedata = []
i = 0
for item in freader:
 i = i + 1
 face_tokens_str = face_tokens_str + item[1] + ','
 if i％5 == 0:
   face_tokens_str = face_tokens_str[:-1]
   facedata.append (face_tokens_str)
   face_tokens_str = ''
face_tokens_str = face_tokens_str[:-1]
facedata.append (face_tokens_str)
csvfile.close()

for item in facedata:
 print(item)
 data = {"api_key":key,"api_secret":secret,"faceset_token":faceset_token,"face_tokens":item}
 response = requests.post(http_url, data=data)
 print(response)
 print(response.text)

初始建立云联数据集的模块： 

#!/usr/bin/env/ python
# _*_ coding:utf-8 _*_

import requests
from json import JSONDecoder

http_url = "https://api-cn.faceplusplus.com/facepp/v3/faceset/create"
get_url = "https://api-cn.faceplusplus.com/facepp/v3/faceset/getfacesets"
getdetails_url = "https://api-cn.faceplusplus.com/facepp/v3/faceset/getdetail"
key = "**********************"
secret = "*********************"

data = {"api_key":key,"api_secret":secret,"display_name":'SEUers',"outer_id":'zbpm'}

repn = requests.post(http_url,data = data)
print(repn)
print(repn.text)
data = {"api_key":key,"api_secret":secret}
repn = requests.post(get_url,data = data)
print(repn)
print(repn.text)
data = {"api_key":key,"api_secret":secret,"outer_id":'zbpm'}
repn = requests.post(getdetails_url,data = data)
print(repn)
print(repn.text)

生成存储facetoken：

这里从171860学号开始生成我的facetoken

#!usr/bin/
# -*- coding: utf-8 -*-
import requests
from json import JSONDecoder
import csv

id = 171860

http_url ='https://api-cn.faceplusplus.com/facepp/v3/detect'
key = "*******************"
secret = "*******************"

faceID_List = []
face_token_List = []
for i in range (0,10):
 faceID = str(id + i)
 file = "picture/"+ faceID + ".jpg"
 data = {"api_key":key,"api_secret":secret,"return_landmark":1,}
 file = {"image_file":open(file,'rb')}

response = requests.post(http_url,data = data,files = file)
 req_con = response.content.decode('utf-8')
 req_dict = JSONDecoder().decode(req_con)
 face_token = req_dict["faces"][0]["face_token"]

faceID_List.append(faceID)
 face_token_List.append(face_token)

print(faceID_List)
print(face_token_List)

csvfile = open('face_token.csv','a',newline = '')
fwriter = csv.writer(csvfile)
for i in range(len(faceID_List)):
   fwriter.writerow([faceID_List[i],face_token_List[i]])
csvfile.close()
