環(huán)境搭建

需要安裝VideoCapture模塊田弥，參考這里：https://blog.csdn.net/zhangbinbinz/article/details/78658619

使用方法

Device()

調(diào)用一個(gè)設(shè)備

saveSnapshot()

拍下照片

舉例-拍一張照片

from VideoCapture import Device
cam = Device()
cam.saveSnapshot('image.jpg')

舉例-持續(xù)拍照并進(jìn)行人臉識(shí)別

（人臉識(shí)別參考百度AI接口調(diào)用）

from VideoCapture import Device
import time, os
import requests
import base64

def get_access_token():
    api_key = ''  #在這里填入自己的key
    secret_key = ''
    url = 'https://aip.baidubce.com/oauth/2.0/token?grant_type=client_credentials&client_id=' + str(api_key) + '&client_secret=' + str(secret_key)

    try:
        res = eval(requests.get(url).text)
        return res['access_token']
    except:
        print("access_token獲取失敗")
        os.system("pause")


def capture_photo():
    try:
        cam = Device()
        cam.saveSnapshot('image.jpg')
    except:
        print("拍照功能出錯(cuò)")


def search_face(access_token):
    
    face_search = 'https://aip.baidubce.com/rest/2.0/face/v3/search' + '?access_token=' + str(access_token)
    header = {
        'Content-Type':'application/json'
    }
    data = {
        "image_type":"BASE64",
        "group_id_list":"group_1",  #這個(gè)要在人臉識(shí)別的應(yīng)用里創(chuàng)建人臉庫矩肩，并添加相應(yīng)圖片
        #這里弄了幾個(gè)明星的照片
    }
    with open('image.jpg', 'rb') as f:
        image = base64.b64encode(f.read())
        data["image"] = str(image, 'utf-8')

    try:
        res2 = eval(requests.post(url=face_search, data=data, headers=header).text)
        #轉(zhuǎn)成dict
        print(res2)
        if res2['error_code'] == 110:
            access_token_new = get_access_token()
            return access_token_new

        print("識(shí)別結(jié)果：", res2["result"]["user_list"][0]["user_id"])
        print("準(zhǔn)確率：", res2["result"]["user_list"][0]["score"])
    except:
        pass
        

if __name__ == '__main__':
    access_token = get_access_token()
    access_token_new = ''

    while True:
        capture_photo()
        if access_token_new:  #access_token過期
            access_token = access_token_new
        access_token_new = search_face(access_token)
