au3抓取摄像头post上传百度AI进行人脸识别

在php, 程序源码 标签 , ,


原理比较简单： 1.利用au3抓取摄像头并拍照，存储在本地。 2.利用au3的post功能将本地照片以base64编码方式上传php服务器。3.php端根据接收到的图片编码，调用百度AI开放平台进行人脸识别。

一些准备工作：
1.1需要自行搭建本地php服务器（假设ip地址为192.168.1.30），可以网上下载phpstudy进行一键安装
1.2下载百度AI人脸识别php包（https://ai.baidu.com/sdk#bfr）
1.3将php包放入新建的aiface文件夹内，将index_au3.php文件放入aiface文件夹
1.4将aiface文件夹放入PHP服务器的web根目录
2.1需要申请注册百度开发者账号（https://login.bce.baidu.com）
2.2选择人脸识别–应用列表–创建应用–（获得AppID API Key Secret Key）
2.3创建后选择该应用进入后–新建用户组：free_face ,本例的用户组名为free_face
2.4修改index_au3.php文件内的AppID API Key Secret Key配置信息

[code]const APP_ID = ‘15462718’;//你的 App ID
const API_KEY = ‘W7Pr4cjQdYLRzsEntHeBFXF4’;//你的 Api Key
const SECRET_KEY = ‘GLh84ZjMczUtaeoDEvS93dpDzSQQzxrp’;//你的 Secret Key[/code]

index_au3.php 返回的是json信息（json里面的score是招牌与人脸库里对比最接近的得分，分数越高越表名是同一个人！分数太低可能导致不同的人被识别成同一个人，我用的是88分以上为同一人）
