本文档将利用京东云AI SDK来实践人脸识别中的人脸搜索功能,主要涉及到分组创建/删除、分组列表获取、人脸创建/删除、人脸搜索,本次实操的最终效果是:创建一个人脸库,拿一张图片在人脸库中搜索出相似度最高的一张,实现1:N的人脸识别,操作示意图如下:
1. 创建AK/SK
登陆京东云控制台:https://console.jdcloud.com,点击右上角账户AccessKey 管理,接着如图点击创建Access Key
2. 购买人脸搜索服务
人脸搜索通过 API 调用次数计费,目前人脸搜索功能有0元免费试用,调用量限制为13
我们登陆到京东云控制台,依次点击左侧导航人工智能-人脸识别-人脸搜索,点击立即购买完成购买操作。
3.下载SDK
购买完成后,返回人脸搜索的控制台,如图点击下载SDK完成京东云AI SDK的下载操作
4.下载Eclipse并安装
Eclipse下载地址:https://www.eclipse.org/downloads/,Eclipse安装方法请自行百度。
1.新建JAVA项目
打开Eclipse,依次点击File-New-Java Project,输入Project name如下图设置后,点击Finish-Don‘t Create
右击JAVA项目中的src目录,依次点击new-Package
接下来我们分别创建分组创建(faceGroupCreate)/删除(faceGroupDelete)、分组列表获取(getFaceGroupList)、人脸创建(faceCreate)/删除(faceDelete)、人脸搜索(faceSearch)相关的(类)Class,新建Class的方法如下:
全部Class创建完成后如下图:
2.装载京东云AI SDK
将我们下载好的京东云AI SDK解压,然后复制到我们新建的JAVA项目的根目录里
刷新Eclipse中的Package Explorer便可看到我们复制进来的京东云AI SDK文件,选中全部jar包文件,右击,依次点击Build Path-Add to Build Path来重新构建路径(Build Path)
重新构建路径完成后,我们在Eclipse的Package Explorer中可看到Referenced Libraries,里面包含我们重构路径的所有jar包
3.调试接口
创建分组(faceGroupCreate)
在faceGroupCreate类中输入如下内容作为调试代码
package facesearch;
import com.jdcloud.apigateway.signature.JdcloudSDKClient;
import com.jdcloud.sdk.utils.BinaryUtils;
import com.google.api.client.http.HttpResponse;
import java.io.IOException;
import java.util.HashMap;
import java.util.Map;
import static com.jdcloud.sdk.http.Protocol.HTTP;
//创建分组
public class faceGroupCreate {
public static void main(String[] args) {
String accessKey = "请输入您的AK";
String secretKey = "请输入您的SK";
String endPoint = "aiapi.jdcloud.com";
String path = "/jdai/faceGroupCreate";
String method = "POST";
Map<String, String> headers = new HashMap<>();
Map<String, Object> queryMap = new HashMap<>();
//queryMap.put("groupId", "10");
queryMap.put("groupName", "请输入分组名称");
queryMap.put("groupInfo", "请输入分组描述");
String body = "\"\"";
try {
HttpResponse response = JdcloudSDKClient.execute(accessKey, secretKey, HTTP,
endPoint, path, method, headers, queryMap, body);
System.out.println(new String(BinaryUtils.toByteArray(response.getContent())));
} catch (IOException e) {
System.out.println(e.getMessage());
}
}
}
右击代码依次点击Run as-1 Java Application运行代码
运行后发现报错信息如下(这里虽然有报错,但我们定义的名称为请输入分组名称的组已成功创建):
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
由此我们可以看出,报出错误的地方主要是slf4j的jar包,而故障码中Failed to load class "org.slf4j.impl.StaticLoggerBinder"的意思则是加载类文件org.slf4j.impl.StaticLoggerBinder时失败
我们下载slf4j-nop.jar,然后像添加AI SDK jar包一样添加到build path中即可解决问题,slf4j-nop.jarjar包我已打包上传到京东云对象存储,下载地址为:https://pocenv-hcc.s3.cn-north-1.jdcloud-oss.com/slf4j-nop-1.7.28.jar
将slf4j包下载后复制到京东云AI SDK文件夹里,然后在Eclipse内添加到构建路径里即可
接下来依次创建其他类文件
注意: 如下代码中涉及到String body = "imageBase64=";的部分
- 需要先将图片转换为Base64,转换地址为:http://imgbase64.duoshitong.com/;
- 然后将转换后的代码复制到imageBase64=之后(转换后的代码需去除掉“data:image/jpeg;base64,”后再复制)。
删除分组(faceGroupDelete
)
package facesearch;
import com.jdcloud.apigateway.signature.JdcloudSDKClient;
import com.jdcloud.sdk.utils.BinaryUtils;

String secretKey = "请输入您的SK";
String endPoint = "aiapi.jdcloud.com";
String path = "/jdai/faceGroupDelete";
String method = "POST";
Map<String, String> headers = new HashMap<>();
Map<String, Object> queryMap = new HashMap<>();
