百度人脸识别
人脸识别（Face Recognition）基于图像或视频中的人脸检测、分析和比对技术，提供对您已获授权前提下的私有数据的人脸检测与属性分析、人脸对比、人脸搜索、活体检测等能力。灵活应用于金融、泛安防、零售等行业场景，满足身份核验、人脸考勤、闸机通行等业务需求
一、官网示例代码
public class Sample {
//设置APPID/AK/SK
public static final String APP_ID = "你的 App ID";
public static final String API_KEY = "你的 Api Key";
public static final String SECRET_KEY = "你的 Secret Key";
public static void main(String[] args) {
// 初始化一个AipFace
AipFace client = new AipFace(APP_ID, API_KEY, SECRET_KEY);
// 可选：设置网络连接参数
client.setConnectionTimeoutInMillis(2000);
client.setSocketTimeoutInMillis(60000);
// 可选：设置代理服务器地址, http和socket二选一，或者均不设置
client.setHttpProxy("proxy_host", proxy_port); // 设置http代理
client.setSocketProxy("proxy_host", proxy_port); // 设置socket代理
// 调用接口
String image = "取决于image_type参数，传入BASE64字符串或URL字符串或FACE_TOKEN字符串";
String imageType = "BASE64";
// 传入可选参数调用接口
HashMap<String, String> options = new HashMap<String, String>();
options.put("face_field", "age");
options.put("max_face_num", "2");
options.put("face_type", "LIVE");
options.put("liveness_control", "LOW");
// 人脸检测
JSONObject res = client.detect(image, imageType, options);
System.out.println(res.toString(2));
}
}
二、项目代码
2.1先测试，FaceApiTest
检测一张图片中是否包含有人脸
package com.itheima.test;
import com.baidu.aip.face.AipFace;
import org.json.JSONObject;
import java.util.HashMap;
public class FaceApiTest {
//设置APPID/AK/SK
public static final String APP_ID = "27915129";
public static final String API_KEY = "iYbOuyOqi9BsVw4SbAEQifgR";
public static final String SECRET_KEY = "Z5kpiL2Fnb1ujQIlcPLjZ9fg0dcAWjaO";
public static void main(String[] args) {
// 初始化一个AipFace
AipFace client = new AipFace(APP_ID, API_KEY, SECRET_KEY);
// 可选：设置网络连接参数
client.setConnectionTimeoutInMillis(2000);
client.setSocketTimeoutInMillis(60000);
// 调用接口
String image = "https://project-of-tanhua.oss-cn-hangzhou.aliyuncs.com/2022/10/14/f716e89e-1364-435a-b3f3-4c9b42d563a2.jpg";
String imageType = "URL";
// 传入可选参数调用接口
HashMap<String, String> options = new HashMap<String, String>();
options.put("face_field", "age");
options.put("max_face_num", "2");
options.put("face_type", "LIVE");
options.put("liveness_control", "LOW");
// 人脸检测
JSONObject res = client.detect(image, imageType, options);
System.out.println(res.toString(2));
}
}
三、抽取模板工具
3.1在tanhua-app-server的applicatin.yaml配置信息
tanhua:
faceapi:
appId: 27915129
apiKey: iYbOuyOqi9BsVw4SbAEQifgR
secret: Z5kpiL2Fnb1ujQIlcPLjZ9fg0dcAWjaO
3.2FaceApiProperties配置类，读取配置
package com.tanhua.autoconfig.properties;
import com.baidu.aip.face.AipFace;
import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
@Data
@ConfigurationProperties("tanhua.faceapi")
public class FaceApiProperties {
private String appId;
private String apiKey;
private String secret;
@Bean
public AipFace client(){
AipFace client = new AipFace(appId, apiKey, secret);
// 可选：设置网络连接参数
client.setConnectionTimeoutInMillis(2000);
client.setSocketTimeoutInMillis(60000);
return client;
}
}
3.3FaceApiTemplate
package com.tanhua.autoconfig.template;
import com.baidu.aip.face.AipFace;
import org.json.JSONObject;
import org.springframework.beans.factory.annotation.Autowired;
import java.util.HashMap;
public class FaceApiTemplate {
@Autowired
private AipFace client;
/**
* 检测图片中是否有人脸
* 需要的参数：
* 本项目可以使用在阿里云oss中上传上去的照片URL
* @param imageUrl
* @return
*/
public boolean checkFace(String imageUrl){
String imageType = "URL";
// 传入可选参数调用接口
HashMap<String, String> options = new HashMap<String, String>();
options.put("face_field", "age");
options.put("max_face_num", "2");
options.put("face_type", "LIVE");
options.put("liveness_control", "LOW");
// 人脸检测
JSONObject res = client.detect(imageUrl, imageType, options);
System.out.println(res.toString(2));
Integer error_code = (Integer) res.get("error_code");
return error_code == 0;
}
}
3.4测试
package com.itheima.test;
import com.tanhua.autoconfig.template.FaceApiTemplate;
import com.tanhua.server.AppServerApplication;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
@RunWith(SpringRunner.class)
@SpringBootTest(classes = AppServerApplication.class)
public class FaceApiTest2 {
@Autowired
private FaceApiTemplate faceApiTemplate;
@Test
public void test (){
String imageUrl = "https://project-of-tanhua.oss-cn-hangzhou.aliyuncs.com/2022/10/14/f716e89e-1364-435a-b3f3-4c9b42d563a2.jpg";
boolean result = faceApiTemplate.checkFace(imageUrl);
System.out.println("图片是否含有人脸？"+result);
}
}
