C#windows窗体人脸识别

一、创建一个数据库，名为TestFaceDB

里面有一张表就OK了，表名Users,表里面有几个字段我说明一下：

id--------------------bigint----------------------编号

name--------------varchar(50)-----------------用户名

phone--------------varchar(50)----------------电话

password--------------varchar(50)------------密码

address--------------varchar(50)--------------地址

picture--------------varchar(50)---------------脸的图片

数据库脚本：

二、引入一个AForgeDLL文件库

C#(Winform)通过添加AForge添加并使用系统摄像机-CSDN博客

三、在vs里面新建个项目 Name： Camtest

在新建个sqlhelper，这个文件是用来操作数据库的，主要是人脸注册和认证以及登陆的时候用。

using System;
using System.Collections.Generic;
using System.Data;
using System.Data.SqlClient;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Data.SqlClient;
using System.Configuration;
using System.Data;namespace face
{/// <summary>/// 数据库工具类/// </summary>public class SqlHelper{#region 获取数据库连接private static string GetConnectionString{get{return "Data Source=.;Initial Catalog=TestFaceDB;Persist Security Info=True;User ID=sa;Password=171268"; //转换成string类型}}#endregion#region 查询多条记录/// <summary>/// 查询多条记录/// params SqlParameter  param  表示既可以传过来数组  也可以传过来单个值/// </summary>/// <param name="sql"></param>/// <param name="type"></param>/// <param name="param"></param>/// <returns></returns>public static SqlDataReader ExcuteReader(string sql, CommandType type, params SqlParameter[] param){SqlConnection conn = new SqlConnection(GetConnectionString);SqlCommand cmd = new SqlCommand(sql, conn);PreaPareCommand(sql, conn, cmd, type, param);//参数是关闭连接return cmd.ExecuteReader(CommandBehavior.CloseConnection);}#endregion#region DataSetpublic static DataSet ExexuteDataset(string sql, CommandType type, params SqlParameter[] param){using (SqlConnection conn = new SqlConnection(GetConnectionString)){SqlCommand cmd = new SqlCommand(sql, conn);PreaPareCommand(sql, conn, cmd, type, param);SqlDataAdapter sda = new SqlDataAdapter(cmd);DataSet ds = new DataSet();sda.Fill(ds);return ds;}}#endregion#region 查询返回一条记录/// <summary>/// 查询返回一条记录/// </summary>/// <param name="sql"></param>/// <param name="type"></param>/// <param name="param"></param>/// <returns></returns>public static Object ExecuteScalar(string sql, CommandType type, params SqlParameter[] param){using (SqlConnection conn = new SqlConnection(GetConnectionString)){SqlCommand cmd = new SqlCommand(sql, conn);PreaPareCommand(sql, conn, cmd, type, param);return cmd.ExecuteScalar();}}#endregion#region 命令对象装配//命令对象装配private static void PreaPareCommand(string sql, SqlConnection conn, SqlCommand cmd, CommandType type, params SqlParameter[] param){if (conn.State != ConnectionState.Open){conn.Close();conn.Open();}cmd.CommandType = type;if (param != null){foreach (SqlParameter p in param){cmd.Parameters.Add(p);}}}#endregion#region 增删改public static int ExecuteNonQuery(string sql, CommandType type, params SqlParameter[] param){using (SqlConnection conn = new SqlConnection(GetConnectionString)){SqlCommand cmd = new SqlCommand(sql, conn);PreaPareCommand(sql, conn, cmd, type, param);return cmd.ExecuteNonQuery();}}#endregion}
}

再新建一个实体类，命名为：Users

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;namespace Camtest
{public class Users{//编号public long id { get; set; }//姓名public string name { get; set; }//密码public string password { get; set; }//年龄public int age { get; set; }//电话public string phone { get; set; }//地址public string address { get; set; }//脸public string picture { get; set; }}
}

四、人脸检测

空间组成：

1. videoSourcePlayer，所在的dll是Aforge.Controls.Video这个里面，名称是videoSourcePlayer1

2. groupBox控件，名称是groupBox1

3.comboBox控件，名称是comboBoxCameras和picsize

4.button控件，名称是button2和close

5. label控件，名称是（左边从上到下）label3，label6，label8，label10，label12，label14。右边从上到下：label4，label5，label7，label9，label11，label13

6窗体，名称是facedetection

1.加载窗体的时候先检测一遍我们的摄像头: 

 // 刷新可用相机的列表videoDevices = new FilterInfoCollection(FilterCategory.VideoInputDevice);comboBoxCameras.Items.Clear();for (int i = 0; i < videoDevices.Count; i++){comboBoxCameras.Items.Add(videoDevices[i].Name.ToString());}if (comboBoxCameras.Items.Count > 0)comboBoxCameras.SelectedIndex = 0;picsize.SelectedIndex = 0;

2.打开摄像头的方法

 /// <summary>/// 打开摄像头/// </summary>public void openCan(){selectedPICIndex = picsize.SelectedIndex;selectedDeviceIndex = comboBoxCameras.SelectedIndex;//连接摄像头。videoSource = new VideoCaptureDevice(videoDevices[selectedDeviceIndex].MonikerString);videoSource.VideoResolution = videoSource.VideoCapabilities[selectedDeviceIndex];// 枚举所有摄像头支持的像素，设置拍照为1920*1080foreach (VideoCapabilities capab in videoSource.VideoCapabilities){if (selectedPICIndex == 0){if (capab.FrameSize.Width == 1920 && capab.FrameSize.Height == 1080){videoSource.VideoResolution = capab;break;}if (capab.FrameSize.Width == 1280 && capab.FrameSize.Height == 720){videoSource.VideoResolution = capab;break;}}else{if (capab.FrameSize.Width == 1280 && capab.FrameSize.Height == 720){videoSource.VideoResolution = capab;break;}}}videoSourcePlayer1.VideoSource = videoSource;// set NewFrame event handlervideoSourcePlayer1.Start();}

3.保存人脸成一张图片，顺便调用人脸检测库：

//保存图片private void button2_Click(object sender, EventArgs e){if (videoSource == null)return;Bitmap bitmap = videoSourcePlayer1.GetCurrentVideoFrame();//图片名称，年月日时分秒毫秒.jpgstring fileName = DateTime.Now.ToString("yyyyMMddHHmmssff") + ".jpg";//获取项目的根目录String path = AppDomain.CurrentDomain.BaseDirectory;//将图片保存在服务器里面bitmap.Save(path + "\\picture\\" + fileName, ImageFormat.Jpeg);bitmap.Dispose();//进行面部特征识别facemodel facem = face_test.FaceDetect(path + "\\picture\\" + fileName);this.label4.Text = facem.age;      //年龄this.label5.Text = facem.beauty;  //漂亮度string expression = facem.expression;//表情if (expression.Equals("0")){this.label7.Text = "不笑";}else if (expression.Equals("1")){this.label7.Text = "微笑";}else if (expression.Equals("2")){this.label7.Text = "大笑";}string gender = facem.gender;//性别if (gender.Equals("male")){this.label9.Text = "男";}else{this.label9.Text = "女";}string glasses = facem.glasses;//是否戴眼镜if (glasses.Equals("0")){this.label11.Text = "无眼镜";}else if (glasses.Equals("1")){this.label11.Text = "普通眼镜";}else{this.label11.Text = "墨镜";}string race = facem.race;//人种if (race.Equals("yellow")){this.label13.Text = "黄人";}else if (race.Equals("white")){this.label13.Text = "白人";}else if (race.Equals("black")){this.label13.Text = "黑人";}else if (race.Equals("arabs")){this.label13.Text = "棕人";}}

4.解析json的类

using face;
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;namespace Camtest
{public class face_test{public static string Api_Key = "你的Api_Key";public static string Secret_Key = "你的Secret_Key";/// <summary>/// 脸部比对/// </summary>/// <param name="img"></param>/// <returns></returns>public static facemodel FaceDetect(String img){var client = new Baidu.Aip.Face.Face(Api_Key, Secret_Key);var image = File.ReadAllBytes(img);var options = new Dictionary<string, object>(){{"face_fields", "age,beauty,expression,gender,glasses,race"}};string result = client.FaceDetect(image, options).ToString();//解析json数据return json_test(result.ToString());}/// <summary>/// 解析json数据/// </summary>/// <param name="json"></param>public static facemodel json_test(string json){//得到根节点JObject jo_result = (JObject)JsonConvert.DeserializeObject(json.ToString());//得到result节点JArray jo_age = (JArray)JsonConvert.DeserializeObject(jo_result["result"].ToString());//查找某个字段与值facemodel facem = new facemodel();foreach (var val in jo_age){facem.age = ((JObject)val)["age"].ToString();facem.beauty = ((JObject)val)["beauty"].ToString();facem.expression = ((JObject)val)["expression"].ToString();facem.gender = ((JObject)val)["gender"].ToString();facem.glasses = ((JObject)val)["glasses"].ToString();facem.race = ((JObject)val)["race"].ToString();}return facem;}}
}

5.人脸检测的model类facemodel

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;namespace face
{public class facemodel{//年龄public string age { get; set; }//美丑public string beauty { get; set; }//表情public string expression { get; set; }//性别public string gender { get; set; }//是否戴眼镜public string glasses { get; set; }//人种public string race { get; set; }}
}

6.人脸检测源代码

}

五、人脸注册

新建一个窗体，名称是：faceregiste

 1.调用的是百度的API，所以需要Api_Key和Secret_Key，关于这两个，大家可以自行百度。

    //Api_Keypublic static string Api_Key = "这里是你的Api_Key";//Secret_Keypublic static string Secret_Key = "这里是你的Secret_Key ";

2.刷新可用摄像头列表

  //加载项目private void faceregiste_Load(object sender, EventArgs e){// 刷新可用相机的列表videoDevices = new FilterInfoCollection(FilterCategory.VideoInputDevice);comboBoxCameras.Items.Clear();for (int i = 0; i < videoDevices.Count; i++){comboBoxCameras.Items.Add(videoDevices[i].Name.ToString());}if (comboBoxCameras.Items.Count > 0)comboBoxCameras.SelectedIndex = 0;picsize.SelectedIndex = 0;//打开摄像头openCamera();}

3..打开摄像头

//打开摄像头public void openCamera() {selectedPICIndex = picsize.SelectedIndex;selectedDeviceIndex = comboBoxCameras.SelectedIndex;//连接摄像头。videoSource = new VideoCaptureDevice(videoDevices[selectedDeviceIndex].MonikerString);videoSource.VideoResolution = videoSource.VideoCapabilities[selectedDeviceIndex];// 枚举所有摄像头支持的像素，设置拍照为1920*1080foreach (VideoCapabilities capab in videoSource.VideoCapabilities){if (selectedPICIndex == 0){if (capab.FrameSize.Width == 1920 && capab.FrameSize.Height == 1080){videoSource.VideoResolution = capab;break;}if (capab.FrameSize.Width == 1280 && capab.FrameSize.Height == 720){videoSource.VideoResolution = capab;break;}}else{if (capab.FrameSize.Width == 1280 && capab.FrameSize.Height == 720){videoSource.VideoResolution = capab;break;}}}videoSourcePlayer1.VideoSource = videoSource;// set NewFrame event handlervideoSourcePlayer1.Start();}

4.点击注册执行的方法

 //注册的按钮private void register_Click(object sender, EventArgs e){Users user = new Users();user.name = this.name.Text;user.id = DateTime.Now.Ticks / 10000;user.password = this.password.Text;user.phone = this.phone.Text;user.age =(int)this.age.Value;user.address = this.address.Text;user.picture = SavePicture() ;//注册人脸通过的话进去if (FaceRegister(user)){int rel = AddUsers(user);//添加信息if (rel > 0){MessageBox.Show("注册成功", "提示信息");}else{MessageBox.Show("添加失败", "提示信息");}}}

5.保存图片方法

/// <summary>/// 保存图片/// </summary>public string SavePicture() {if (videoSource == null){return null;}Bitmap bitmap = videoSourcePlayer1.GetCurrentVideoFrame();//图片名称，年月日时分秒毫秒.jpgstring fileName = DateTime.Now.ToString("yyyyMMddHHmmssff") + ".jpg";//获取项目的根目录string path = AppDomain.CurrentDomain.BaseDirectory;string picture = path + "\\picture\\" + fileName;//将图片保存在服务器里面bitmap.Save(picture, ImageFormat.Jpeg);bitmap.Dispose();return picture;}

6.取消按钮方法

 //取消的按钮private void close_Click(object sender, EventArgs e){//停止摄像头videoSourcePlayer1.Stop();this.Close();welcome we = new welcome();we.Show();}

7..用户注册的方法

/// <summary>/// 用户注册/// </summary>/// <param name="users"></param>/// <returns></returns>public int AddUsers(Users users){int rel = 0;string sql = "insert INTO Users VALUES(@id,@name,@age,@phone,@password,@address,@picture)";SqlParameter[] param = {new SqlParameter("@id",users.id),new SqlParameter("@name",users.name),new SqlParameter("@age",users.age),new SqlParameter("@phone",users.phone),new SqlParameter("@password",users.password),new SqlParameter("@address",users.address),new SqlParameter("@picture",users.picture)};rel = SqlHelper.ExecuteNonQuery(sql, CommandType.Text, param);return rel;}

8.人脸注册方法

 /// <summary>/// 人脸注册/// </summary>/// <param name="picture"></param>public static bool FaceRegister(Users user){var client = new Baidu.Aip.Face.Face(Api_Key, Secret_Key);//当前毫秒数可能是负数，取绝对值var image1 = File.ReadAllBytes(user.picture);var result = client.User.Register(image1, user.id.ToString(), user.name, new[] { "gr_test" });//得到根节点JObject jo_result = (JObject)JsonConvert.DeserializeObject(result.ToString());if ((string)jo_result["error_msg"] != null){MessageBox.Show("对不起，请把脸放上！","提示",MessageBoxButtons.OK,MessageBoxIcon.Stop);return false;}return true;}

9.关闭窗体方法

 //关闭窗体private void faceregiste_FormClosing(object sender, FormClosingEventArgs e){DialogResult r = MessageBox.Show("确定要退出程序?", "操作提示", MessageBoxButtons.OKCancel, MessageBoxIcon.Question);if (r != DialogResult.OK){e.Cancel = true;}videoSourcePlayer1.Stop();//停止摄像头videoSourcePlayer1.Dispose();}

}

六、人脸登录

1. 窗体加载刷新摄像头列表：

//窗体加载private void faceIdentify_Load(object sender, EventArgs e){//显示为正在检测this.label1.Text = this.label2.Text = this.label6.Text = this.label9.Text = "正在识别";// 刷新可用相机的列表videoDevices = new FilterInfoCollection(FilterCategory.VideoInputDevice);comboBoxCameras.Items.Clear();for (int i = 0; i < videoDevices.Count; i++){comboBoxCameras.Items.Add(videoDevices[i].Name.ToString());}if (comboBoxCameras.Items.Count > 0)comboBoxCameras.SelectedIndex = 0;picsize.SelectedIndex = 0;//打开摄像头openCamera();}

2.打开摄像头：

4.人脸认证【登陆】：

/// <summary>/// 人脸认证【登陆】/// </summary>public  void FaceVerify(string filename,Users users){var client = new Baidu.Aip.Face.Face(Api_Key ,Secret_Key);var image1 = File.ReadAllBytes(filename);var result = client.User.Verify(image1,(users.id).ToString(), new[] { "gr_test" }, 1);//先判断脸是不是在上面，在继续看有匹配的没，否则提示放上脸//得到根节点JObject jo_result = (JObject)JsonConvert.DeserializeObject(result.ToString());if ((string)jo_result["error_msg"] != null){MessageBox.Show("对不起，请把脸放上！", "提示", MessageBoxButtons.OK, MessageBoxIcon.Stop);}else{//检测到脸//得到result节点JArray jo_age = (JArray)JsonConvert.DeserializeObject(jo_result["result"].ToString());string resu = jo_age.ToString();int num1 = resu.IndexOf("\n") + 2;int num2 = resu.LastIndexOf("]") - 8;string ids = resu.Substring(num1, num2);if (ids != null || !ids.Equals("")){double scores_num = double.Parse(ids);if (scores_num > 80){MessageBox.Show("登陆成功，已检测到您的信息", "操作提示", MessageBoxButtons.OK, MessageBoxIcon.Information);}else{MessageBox.Show("对不起，脸与账户不对应，请换张脸试试", "操作提示", MessageBoxButtons.OK, MessageBoxIcon.Stop);}}}}

5.根据编号查询用户信息：

/// <summary>/// 根据编号查询用户信息/// </summary>/// <param name="id"></param>/// <returns></returns>public static Users QueryUsersByName(string name){Users user = new Users();string sql = "select * from users where name = @name";using (SqlDataReader reader = SqlHelper.ExcuteReader(sql, CommandType.Text, new SqlParameter("@name", name))){if (reader.Read()){user.id = long.Parse(reader[0].ToString());user.name = reader[1].ToString();user.age = Convert.ToInt32(reader[2]);user.phone = reader[3].ToString();user.password = reader[4].ToString();user.address = reader[5].ToString();user.picture = reader[6].ToString();}}return user;}

6..保存图片：

  /// <summary>/// 保存图片/// </summary>public string SavePicture(){if (videoSource == null){return null;}Bitmap bitmap = videoSourcePlayer1.GetCurrentVideoFrame();//图片名称，年月日时分秒毫秒.jpgstring fileName = DateTime.Now.ToString("yyyyMMddHHmmssff") + ".jpg";//获取项目的根目录string path = AppDomain.CurrentDomain.BaseDirectory;string picture = path + "\\picture\\" + fileName;//将图片保存在服务器里面bitmap.Save(picture, ImageFormat.Jpeg);bitmap.Dispose();return picture;}
