這篇文章主要為大家詳細介紹了face++與python實現(xiàn)人臉識別簽到(考勤)功能，具有一定的參考價值，感興趣的小伙伴們可以參考一下

項目實現(xiàn)利用face++開發(fā)一個課堂簽到的軟件，實現(xiàn)面向攝像頭即可完成記錄學(xué)號、姓名和時間的簽到工作。

項目架構(gòu)

項目使用場景

代碼：

流程代碼，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"

getdetail_url = "https://api-cn.faceplusplus.com/facepp/v3/faceset/getdetail"

key = "***************"

secret = "*********************"

filename = time.time()

filepath = "photo/" + str(filename) + ".jpg"

cap = cv2.VideoCapture(0)

while(1):

# get a frame

ret, frame = cap.read()

# show a frame

cv2.imshow("capture", frame)

if cv2.waitKey(1) & 0xFF == ord('1'):

cv2.imwrite(filepath, frame)

break

cap.release()

cv2.destroyAllWindows()

print("waiting...")

csvfile = open('face_token.csv','r')

freader = csv.reader(csvfile)

print("...")

print("...")

if pre_face_token in faces_token and pre_confidence >= pre_thresholds:

建立云臉數(shù)據(jù)集的模塊：

#!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)

初始建立云聯(lián)數(shù)據(jù)集的模塊：

#!/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)

生成存儲facetoken：

這里從171860學(xué)號開始生成我的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()

非常感謝你的閱讀

大學(xué)的時候選擇了自學(xué)python，工作了發(fā)現(xiàn)吃了計算機基礎(chǔ)不好的虧，學(xué)歷不行這是

沒辦法的事，只能后天彌補，于是在編碼之外開啟了自己的逆襲之路，不斷的學(xué)習(xí)python核心知識，深入的研習(xí)計算機基礎(chǔ)知識，整理好了，如果你也不甘平庸，那就與我一起在編碼之外，不斷成長吧！

其實這里不僅有技術(shù)，更有那些技術(shù)之外的東西，比如，如何做一個精致的程序員，而不是“屌絲”，程序員本身就是高貴的一種存在啊，難道不是嗎？[點擊加入]想做你自己想成為高尚人，加油！
