    本期教程人脸识别第三方平台为虹软科技,基于Java开发，本文章讲解的是人脸识别RGB活体追踪技术，免费的功能很多可以自行搭配，希望在你看完本章课程有所收获。

    人脸追踪示例

    ArcFace 离线SDK，包含人脸检测、性别检测、年龄检测、人脸识别、图像质量检测、RGB活体检测、IR活体检测等能力，初次使用时需联网激活，激活后即可在本地无网络环境下工作，可根据具体的业务需求结合人脸识别SDK灵活地进行应用层开发。

    功能介绍

    1. 人脸检测

    对传入的图像数据进行人脸检测，返回人脸的边框以及朝向信息，可用于后续的人脸识别、特征提取、活体检测等操作;

    • 支持IMAGE模式和VIDEO模式人脸检测。
    • 支持单人脸、多人脸检测，最多支持检测人脸数为50。

    2.人脸追踪

    对来自于视频流中的图像数据，进行人脸检测，并对检测到的人脸进行持续跟踪。(我们是实时的所以就只能使用第三方操作,先不使用这个)

    3.人脸特征提取

    提取人脸特征信息，用于人脸的特征比对。

    4.人脸属性检测

    人脸属性，支持检测年龄、性别以及3D角度。

    人脸3D角度：俯仰角(pitch)， 横滚角(roll)， 偏航角(yaw)。

    5.活体检测

    离线活体检测，静默式识别，在人脸识别过程中判断操作用户是否为真人，有效防御照片、视频、纸张等不同类型的作弊攻击，提高业务安全性，让人脸识别更安全、更快捷，体验更佳。支持单目RGB活体检测、双目(IR/RGB)活体检测，可满足各类人脸识别终端产品活体检测应用。

    47.  
    48.     @Override
    49.     public PooledObject<FaceEngine> wrap (FaceEngine faceEngine) {
    50.         return new DefaultPooledObject<>(faceEngine);
    51.     }
    52.  
    53.  
    54.     @Override
    55.     public void destroyObject (PooledObject<FaceEngine> p) throws Exception {
    56.         FaceEngine faceEngine = p.getObject();
    57.         int unInitCode = faceEngine.unInit();
    58.         super.destroyObject(p);
    59.         log.info("销毁对象完毕! faceEngineUnInitCode: {}", unInitCode);
    60.     }
    61. }

    一、编写人脸识别业务接口

    在service目录下创建-> FaceEngineService

    1. package top.yangbuyi.service;
    2.  
    3. import com.arcsoft.face.FaceInfo;
    4. import com.arcsoft.face.toolkit.ImageInfo;
    5. import top.yangbuyi.dto.FaceUserInfo;
    6. import top.yangbuyi.dto.ProcessInfo;
    7.  
    8. import java.util.List;
    9. import java.util.concurrent.ExecutionException;
    10.  
    11. /**
    12.  * 人脸识别接口
    13.  */
    14. public interface FaceEngineService {
    15.  
    16.     /**
    17.      * 人脸检测
    18.      * @param imageInfo
    19.      * @return
    20.      */
    21.     List<FaceInfo> detectFaces (ImageInfo imageInfo);
    22.  
    23.     /**
    24.      * 提取年龄-性别
    25.      * @param imageInfo
    26.      * @return
    27.      */
    28.     List<ProcessInfo> process (ImageInfo imageInfo);
    29.  
    30.     /**
    31.      * 人脸特征
    32.      * @param imageInfo
    33.      * @return
    34.      */
    35.     byte[] extractFaceFeature (ImageInfo imageInfo) throws InterruptedException;
    36.  
    37.     /**
    38.      * 人脸比对
    39.      * @param groupId
    40.      * @param faceFeature
    41.      * @return
    42.      */
    43.     List<FaceUserInfo> compareFaceFeature (byte[] faceFeature, Integer groupId) throws InterruptedException, ExecutionException;
    44.  
    45. }

    service.impl 包下创建 FaceEngineServiceImpl 实现类

    人脸识别逻辑

    1、必须进行人脸特征获取 -> 特征获取成功 -> 进入人脸对比 -> 人脸检测 -> 返回人脸数据
    2、必须进行人脸特征获取 -> 特征获取失败 -> 直接跳出返回 未检出到人脸

    编写人脸特征获取逻辑

    83.     }
    84.  
    85. }

    编写根据根据分组ID获取人脸库数据

    在mapper下SysUserFaceInfoMapper -> 创建接口 getUserFaceInfoByGroupId

    1. /**
    2.  * 根据分组Id
    3.  * 从数据库中取出人脸库
    4.  *
    5.  * @param groupId
    6.  * @return 人脸库
    7.  */
    8.     List<FaceUserInfo> getUserFaceInfoByGroupId(Integer groupId);

    sql实现

    1. <resultMap id="userFace2" type="top.yangbuyi.dto.FaceUserInfo">
    2. <id column="id" property="id" javaType="int"/>
    3. <result column="group_id" property="groupId" javaType="java.lang.Integer"/>
    4. <result column="name" property="name" javaType="java.lang.String"/>
    5. <result column="face_id" property="faceId" javaType="String"/>
    6. <result column="face_feature" property="faceFeature"/>
    7. </resultMap>
    8.  
    9. <
    10. select id = "getUserFaceInfoByGroupId" resultMap="userFace2" parameterType="java.lang.Integer"
    11.         resultType="top.yangbuyi.dto.FaceUserInfo">
    12. select id, group_id, face_id, name, face_feature
    13. from `sys_user_face_info`
    14. where group_id = #{groupId}
    15.           < /
    16. select>

    二、编写人脸添加业务接口

    userFaceInfoService 新增人脸业务接口

    1. /**
    2.  * 新增用户人脸识别
    3.  *
    4.  * @param sysUserFaceInfo 用户人脸识别
    5.  * @return 结果
    6.  */
    7. public int insertSysUserFaceInfo(SysUserFaceInfo sysUserFaceInfo);
    就是一共简简单单的新增插入数据 这个就不用我教了吧？？？？？？？？？

    image-1652677051101

    三、 编写Controller业务控制层

    1. import top.yangbuyi.domain.AjaxResult;
    2.  
    3. /**
    4.  * (sys_user_face_info)表控制层
    5.  *
    6.  * @author yangbuyi.top
    7.  */
    8. @RestController
    9. @Slf4j
    10. @RequestMapping("face")
    11. @RequiredArgsConstructor
    12. public class SysUserFaceInfoController {
    13.     public final static Logger logger = LoggerFactory.getLogger(SysUserFaceInfoController.class);
    14.  
    15.     private final FaceEngineService faceEngineService;
    16.  
    17.     private final SysUserFaceInfoService userFaceInfoService;
    18.  
    19.  
    20.     /**
    21.      * 人脸添加
    22.      *
    23.      * @param file    人脸附件
    24.      * @param groupId 分组id
    25.      * @param name    用户登录名称
    26.      */
    27.     @RequestMapping(value = "/faceAdd", method = RequestMethod.POST)
    28.     public AjaxResult faceAdd (@RequestBody Map<String, Object> map) {
    29.         // 业务.... yangbuyi.top 版权所有
    30.         return AjaxResult.success();
    31.     }
    32.  
    33.  
    34.     /**
    35.      * 人脸识别
    36.      *
    37.      * @param file    人脸附件
    38.      * @param groupId 分组ID 方便快速识别
    39.      */
    40.     @RequestMapping(value = "/faceSearch", method = RequestMethod.POST)
    41.     public AjaxResult faceSearch (@RequestBody Map<String, Object> map) throws Exception {
    42.         // 业务... yangbuyi.top 版权所有
    43.         return AjaxResult.success();
    44.     }

    faceAdd 具体业务编写

    1. 根据前端传递的
      file -> 人脸图片
      groupId -> 用户分组(用于缩小范围查询该人员的位置有效减少数据量大的问题)
      name -> 当前用户名称(实际开发当中应该是存储id)
    1. String file = String.valueOf(map.get("file"));
    2.         String groupId = String.valueOf(map.get("groupId"));
    3.         String name = String.valueOf(map.get("name"));
    4.         try {
    5.             if (file == null) {
    6.                 return AjaxResult.error("file is null");
    7.             }
    8.             if (groupId == null) {
    9.                 return AjaxResult.error("file is null");

    faceSearch 具体业务编写

    1. 根据前端传递的
      file -> 人脸图片
      groupId -> 用户分组(用于缩小范围查询该人员的位置有效减少数据量大的问题)
    1. String file = String.valueOf(map.get("file"));
    2.         String groupId = String.valueOf(map.get("groupId"));
    3.  
    4.         if (groupId == null) {
    5.             return AjaxResult.error("groupId is null");
    6.         }
    7.         byte[] decode = Base64.decode(base64Process(file));
    8.         BufferedImage bufImage = ImageIO.read(new ByteArrayInputStream(decode));
    9.         ImageInfo imageInfo = ImageFactory.bufferedImage2ImageInfo(bufImage);
    10.  
    11.  
    12.         //人脸特征获取
    13.         byte[] bytes = faceEngineService.extractFaceFeature(imageInfo);
    14.         // 校验是否显示出人脸
    15.         if (bytes == null) {
    16.             return AjaxResult.error(ErrorCodeEnum.NO_FACE_DETECTED.getDescription());
    17.         }
    18.  
    19.         //人脸比对，获取比对结果
    20.         List<FaceUserInfo> userFaceInfoList = faceEngineService.compareFaceFeature(bytes, Integer.valueOf(groupId));

    32.                 int width = faceInfoList.get(0).getRect().getRight() - left;
    33.                 int height = faceInfoList.get(0).getRect().getBottom() - top;
    34.  
    35.                 Graphics2D graphics2D = bufImage.createGraphics();
    36.                 // 红色

    40.                 graphics2D.drawRect(left, top, width, height);
    41.                 ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
    42.                 ImageIO.write(bufImage, "jpg", outputStream);
    43.                 byte[] bytes1 = outputStream.toByteArray();
    44.                 faceSearchResDto.setImage("data:image/jpeg;base64," + Base64Utils.encodeToString(bytes1));
    45.                 faceSearchResDto.setAge(processInfoList.get(0).getAge());
    46.                 faceSearchResDto.setGender(processInfoList.get(0).getGender().equals(1) ? "女" : "男");
