阿里雲人臉識別 1:N 使用簡明示例

2020-04-03

作者：俏巴

概述

基於圖像或視頻輸入進行檢測，與註冊庫比對，實現1：N的人臉識別。適用於人臉登錄、VIP人臉識別、人臉通關等無需刷卡驗證的場景。目前人臉識別1:N功能已經正式商業化。下面主要演示1:N 服務的開通及Java程序的調用測試。

服務開通

1、複製粘貼地址到瀏覽器打開鏈接:https://common-buy.aliyun.com/?commodityCode=face_pre#/open 開通服務(注意複製粘貼操作，不要直接點擊，地址跳轉可能會存在錯誤)。
_

2、到費用中心支付。
_

3、登陸控制檯查看(現階段管理控制檯功能還不完善，不過不影響程序的測試調用)。

Java Code Sample

1、pom.xml

        <dependency>
        <span class="xml"><span class="hljs-tag">&lt;<span class="hljs-name">groupId</span>&gt;</span>com.aliyun<span class="hljs-tag">&lt;/<span class="hljs-name">groupId</span>&gt;</span></span>
        &lt;artifactId&gt;aliyun-java-sdk-core&lt;<span class="hljs-regexp">/artifactId&gt;
        &lt;version&gt;4.1.1&lt;/</span>version&gt;
    <span class="xml"><span class="hljs-tag">&lt;/<span class="hljs-name">dependency</span>&gt;</span></span></code></pre>
