python3.7使用百度ai实现人脸识别_python调用百度API实现人脸识别

1、代码

from aip import AipFace

import cv2

import time

import base64

from PIL import Image

from io import BytesIO

import pyttsx3

# """ 你的 APPID AK SK """

APP_ID = '1965####'

API_KEY = 'YXL65ekIloykyjrT4kzc####'

SECRET_KEY = 'lFiapBoZ5eBwOFyxMbiwQDmClg1u####'

client = AipFace(APP_ID, API_KEY, SECRET_KEY)

# def frame2base64(frame):

# img = Image.fromarray(frame) #将每一帧转为Image

# output_buffer = BytesIO() #创建一个BytesIO

# img.save(output_buffer, format='JPEG') #写入output_buffer

# byte_data = output_buffer.getvalue() #在内存中读取

# image = base64.b64encode(byte_data) #转为BASE64

# return image #转码成功 返回base64编码

def generate():

camera = cv2.VideoCapture(0)

engine = pyttsx3.init()

try:

while True:

engine = pyttsx3.init()

ret, img = camera.read()

cv2.imwrite("E://Ana/face.png",img)

cv2.imshow("调用摄像头", img)

imageType = "BASE64"

groupIdList = "1,2,3,4"

""" 如果有可选参数 """

options = {}

options["max_face_num"] = 4

options["match_threshold"] = 70

options["quality_control"] = "NORMAL"

options["liveness_control"] = "NONE"

# options["user_id"] = "233451"

options["max_user_num"] = 4

# """ 带参数调用人脸搜索 """

with open("E://Ana/face.png", 'rb') as fp:

imageB = base64.b64encode(fp.read())

image = str(imageB, 'utf-8')

""" 调用人脸搜索 """

result = client.search(image, imageType, groupIdList, options)

engine.runAndWait()

print(2)

if result:

if not result['result']:

continue

name = result['result']['user_list'][0]['user_id']#获取名字

score = result['result']['user_list'][0]['score']#获取相似度

if name == 'cgh_1':

if score>80:

print(score)

print(name)

engine.say("华来了")

elif name == 'yjc_1':

if score > 80:

print(score)

print(name)

engine.say("杨来了")

elif name == 'cjy_1':

if score > 80:

print(score)

print(name)

engine.say("言来了")

elif name == 'hjy_1':

if score > 80:

print(score)

print(name)

engine.say("怡来了")

else:

print("匹配失败")

else:

continue

except Exception as e:

print(e)

finally:

# 释放资源

engine.runAndWait()

camera.release()

cv2.destroyAllWindows()

generate()

2、实现步骤

2.1、获取百度ID和key

在百度API中可以申请到免费的API账号，每天有免费的几千次人脸识别，下图为我申请的API账号，然后在人脸库中创建需要识别的人脸就行了

2.2、创建客户端

APP_ID = '1965####'

API_KEY = 'YXL65ekIloykyjrT4kzc####'

SECRET_KEY = 'lFiapBoZ5eBwOFyxMbiwQDmClg1u####'

client = AipFace(APP_ID, API_KEY, SECRET_KEY)

2.3、实现人脸识别

主要内容就是参数需要自己修改，然后获取视频图像，然后通过对比看一下，对比出来的名字，然后再看一下分数即可，我在里面加了一个电脑播报的，所以只要识别出来，电脑就会播报，延迟不超过以秒。
