ArcFaceSharp

NuGet

ArcFaceSharp 是 ArcSoft 虹软 ArcFace 2.0 SDK (http://ai.arcsoft.com.cn/product/arcface.html) 的一个 C# 封装库,为方便进行 C# 开发而封装。欢迎 Start & Fork。

使用

在 Nuget 搜索 ArcFaceSharp 安装。

PM> Install-Package ArcFaceSharp -Version 1.0.2

或者下载dll导入。

导入 ArcFaceSharp 后,将自己申请到的 ArcFace2.0 SDK 的 dll 文件 (libarcsoft_face.dll 和 libarcsoft_face_engine.dll)放在程序的运行目录下。

接口调用的流程可参考官方文档的流程图(http://ai.arcsoft.com.cn/manual/arcface_windows_guideV2.html 2.1.5调用流程)

  • lct
主要 API

具体参数和含义可以自行查看方法的注释

  • 激活及初始化

    创建 ArcFaceCore对象即可

ArcFaceCore arcFaceCore = ArcFaceCore(appId, sdkKey, detectMode, combinedMask,detectFaceOrientPriority, detectFaceMaxNum,detectFaceScaleVal);
  • 将 Bitmap 转换成 ImageData
ImageData imageData = ImageDataConverter.ConvertToImageData(bitmap);

以下方法都是 ArcFaceCore 中的方法

  • 人脸检测
MultiFaceModel multiFaceModel = arcFaceCore.FaceDetection(imageData);
  • 人脸信息检测(年龄/性别/人脸3D角度)最多支持4张人脸信息检测,超过部分返回未知
// 人脸信息检测 先调用这个接口才能获取以下三个信息
arcFaceCore.FaceProcess(imageData,multiFaceModel);
//获取年龄信息
List<int> ageList = arcFaceCore.GetAge();
// 获取性别信息
List<int> genderList = arcFace.GetGender();
// 获取人脸角度信息
List<Face3DAngleModel> face3DAngleList = arcFace.GetFace3DAngle();
  • 人脸特征值提取

    asfSingleFaceInfo 为人脸检测接口返回的人脸信息中的其中一个人脸信息

AsfFaceFeature asfFaceFeature = arcFace.FaceFeatureExtract(imageData, ref asfSingleFaceInfo);
  • 人脸对比
 float result = arcFace.FaceCompare(asfFaceFeature1, asfFaceFeature2);
  • 异常捕获

    以人脸特征提取为例,当借口返回值不为 0(成功)时,则会抛出 ResultCodeException 异常。

try
{
	AsfFaceFeature asfFaceFeature = arcFace.FaceFeatureExtract(imageData, ref asfSingleFaceInfo);
}
catch (ResultCodeException e)
{
   Console.WriteLine(e.ResultCode);
   throw;
}

代码示例:

\ArcFaceSharpUnitTest\UnitTest1.cs

      public void TestMethod1()
        {

            // SDK对应的 APP_ID SDK_KEY
            string APP_ID = @"7NK7KSpfgxdqb74r8nvy36kDwH3wVGstr2LHGHBxQ8LY";
 
            string SDK_KEY =  @"3fD8vKYMNfPzKHMoqppjA9chGh2aGkWzUQNFiAj7Yq63";

            // 加载图片
            Bitmap heying = new Bitmap(@"heying.jpg");

            Bitmap face1 = new Bitmap(@"ldh0.jpg");
            Bitmap face2 = new Bitmap(@"ldh1.jpg");

            Bitmap face3 = new Bitmap(@"zxy0.jpg");

            // 创建 ArcFaceCore 对象,向构造函数传入相关参数进行 ArcFace 引擎的初始化
            ArcFaceCore arcFace = new ArcFaceCore(APP_ID,SDK_KEY,ArcFaceDetectMode.IMAGE,
                ArcFaceFunction.FACE_DETECT | ArcFaceFunction.FACE_RECOGNITION | ArcFaceFunction.AGE | ArcFaceFunction.FACE_3DANGLE | ArcFaceFunction.GENDER,DetectionOrientPriority.ASF_OP_0_ONLY,50,32);

            // 将 Bitmap 转换成 ImageData
            ImageData heyingImgData = ImageDataConverter.ConvertToImageData(heying);

            // 人脸检测
            // 也可直接传入 Bitmap 来调用相关接口 会自动转换成 ImageData,但这里推荐用 ImageData
            MultiFaceModel multiFaceB = arcFace.FaceDetection(heying);
            // 传入 ImageData ,推荐使用这个接口
            MultiFaceModel multiFace = arcFace.FaceDetection(heyingImgData);

            // 人脸信息检测(年龄/性别/人脸3D角度)最多支持4张人脸信息检测,超过部分返回未知 这是官方文档的说明
            arcFace.FaceProcess(heyingImgData, multiFace);

            // 获取年龄信息
            List<int> ageList = arcFace.GetAge();
            // 获取性别信息
            List<int> genderList = arcFace.GetGender();
            // 获取人脸角度信息
            List<Face3DAngleModel> face3DAngleList = arcFace.GetFace3DAngle();


            // 将第一张图片的 Bitmap 转换成 ImageData
            ImageData faceData1 = ImageDataConverter.ConvertToImageData(face1);

            // 检测第一张图片中的人脸
            MultiFaceModel multiFace1 =  arcFace.FaceDetection(faceData1);
             
            // 取第一张图片中返回的第一个人脸信息
            AsfSingleFaceInfo faceInfo1 = multiFace1.FaceInfoList.First();

            // 提第一张图片中返回的第一个人脸的特征
            AsfFaceFeature faceFeature1 = arcFace.FaceFeatureExtract(faceData1, ref faceInfo1);



            ImageData faceData2 = ImageDataConverter.ConvertToImageData(face2);

            // 检测第二张图片中的人脸
            MultiFaceModel multiFace2 = arcFace.FaceDetection(faceData2);

            // 取第二张图片中返回的第一个人脸信息
            AsfSingleFaceInfo faceInfo2 = multiFace2.FaceInfoList.First();

            // 提第二张图片中返回的第一个人脸的特征
            AsfFaceFeature faceFeature2 = arcFace.FaceFeatureExtract(faceData2, ref faceInfo2);



            // face1 face2 人脸对比,将会返回一个 0-1 之间的浮点数值
            float result = arcFace.FaceCompare(faceFeature1, faceFeature2);



            ImageData faceData3 = ImageDataConverter.ConvertToImageData(face3);

            // 检测第三张图片中的人脸
            MultiFaceModel multiFace3 = arcFace.FaceDetection(faceData3);

            // 取第三张图片中返回的第一个人脸信息
            AsfSingleFaceInfo faceInfo3 = multiFace3.FaceInfoList.First();

            // 提第三张图片中返回的第一个人脸的特征
            AsfFaceFeature faceFeature3 = arcFace.FaceFeatureExtract(faceData3, ref faceInfo3);

            // face1 face3 人脸对比,将会返回一个 0-1 之间的浮点数值
            float result2 = arcFace.FaceCompare(faceFeature1, faceFeature3);


            // 释放销毁引擎
            arcFace.Dispose();
            // ImageData使用完之后记得要 Dispose 否则会导致内存溢出 
            faceData1.Dispose();
            faceData2.Dispose();
            // BItmap也要记得 Dispose
            face1.Dispose();
            face2.Dispose();         
        }
