python调用百度API实现人脸识别

1、代码

from aip import AipFaceimport cv2import timeimport base64from PIL import Imagefrom io import BytesIOimport 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’]: continuename = 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。
