使用虹軟ArcFac，java 離線SDK 進行人臉識別

   公司項目需要人臉識別登錄,需要支持離線識別,所以無法使用在線的人臉識別的API,於是使用到了離線SDK來對比識別人臉相識度.

   獲取人臉抓拍的圖片需要對接設備,這里不做記錄,假設我們已經獲取到了人臉圖片,只調用SDK將抓拍的人臉圖片與已有的進行人臉庫圖片對比,具體步驟如下:

  

1.  注冊賬號,實名認證

     https://ai.arcsoft.com.cn/ucenter/user/userlogin

 

2. 創建應用,在我的應用里面添加SDK,下載sdk到本地

  

 

 

3. 解壓SDK,將SDK下的libs文件夾的庫文件放到jdk下的lib文件夾下

 

 

 

 

4. 將SDK  libs文件夾下的jar文件導入項目,然后buildpath

 

 

 

 

5. 編寫測試代碼,進行人臉比對

6.運行main方法測試

 

注意事項:

A: 虹軟人臉識別離線 SDK 每台機器對應一個SDK,第一次激活SDK會與機器綁定,不同的機器需要下載新的SDK
B: 離線 SDK自下載之日起,有效期一年,一年使用時間過后,需要重新下載最新版,同時更新對應的 dll文件, appid 和sdkkey,更新之后請更新以上的APP ID 和 SDK KEY
C: 具體詳見官網 https://ai.arcsoft.com.cn/
