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 然后我吧数据库脚本放上来

以上就是准备工作的数据库
二、在VS里面写代码之前我们需要引入一个AForgeDLL文件库
下载地址 C#处理视频dll库AForge下载安装版
三、在vs里面新建个项目名称是Camtest
新建完项目之后我们在新建个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。源码在这里 C#人脸识别——————SqlHelper 新建一个实体类名称就随便起个吧我们命名为Users源码在这里 C#人脸识别——————Users
四、人脸检测
接下来我们就开始写窗体一步一步的来接着往下看我们先来整一个人脸检测的玩玩练练手吧 这个是人脸检测的运行结果图我们不注重界面的美化我们只注重功能的实现。接下来我们分析一下这个窗体是由哪些控件组成的 序号对应控件说明 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label3label6label8label10label12label14。右边从上到下label4label5label7label9label11label13 6--------------------窗体名称是facedetection 接着我们看一下这个窗体内部的实现代码 1.首先引入AForge的命名空间、
using AForge;
using AForge.Controls;
using AForge.Imaging;
using AForge.Video;
using AForge.Video.DirectShow;2.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;3.打开摄像头的方法 /// summary/// 打开摄像头/// /summarypublic 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();}
4.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;}}
在上面的这个方法里面我们需要一个解析json的类类的源码在 人脸检测解析json的工具类face_test 还有一个model类类的源码在 人脸检测的model类facemodel 这就是我们主要的功能实现整个窗体的源码请移步到这里面看 人脸检测源码facedetection 最后完美运行。
五、人脸注册
1.新建一个窗体名称是faceregiste 下面是运行结果 至于控件什么的我就不说的那么详细了大家一看就知道用的什么控件了。 2.由于调用的是百度的API所以需要Api_Key和Secret_Key关于这两个大家可以自行百度。所以先声明一下 //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 ;3.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();}5.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();}6.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);}}}
7.保存图片的方法
/// summary/// 保存图片/// /summarypublic 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;}8.取消按钮的方法 //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();}10.用户注册的方法
/// summary/// 用户注册/// /summary/// param nameusers/param/// returns/returnspublic 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;}11.人脸注册的方法 /// summary/// 人脸注册/// /summary/// param namepicture/parampublic 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;}12.关闭窗体的方法 //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();}源码请到这里来看 人脸注册源码faceregiste
六、人脸认证
1.新建一个窗体名称为faceIdentify其运行结果是 这些控件的名称我也不多说基本都能知道下面我们来介绍一下代码 2.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();}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.签到的按钮
