上周子啊项目开发中用到了百度API调用来识别人脸特征,当时主要是用来处理用户登录模块对用户进行信息校验。我将调用百度API接口实现人脸识别的过程分享给大家,喜欢的朋友请往下看。
一、调用百度API实现人脸识别核心代码
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()
二、调用百度API实现人脸识别的步骤
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
在这里插入图片描述
在这里插入图片描述
2、创建客户端
APP_ID = '1965####'
API_KEY = 'YXL65ekIloykyjrT4kzc####'
SECRET_KEY = 'lFiapBoZ5eBwOFyxMbiwQDmClg1u####'
client = AipFace(APP_ID, API_KEY, SECRET_KEY)
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。
