AForge.net如何加到C#工程里边

首先用到AForge类库下载地址

然后引用AForge,AForge.Controls(这个是控件，可以添加到工具箱中洞枣),AForge.Imaging,AForge.Video,AForge.Video.DirectShow

然后直接上代码

[csharp] view plain copy print?

private FilterInfoCollection videoDevices

private VideoCaptureDevice videoSource

public int selectedDeviceIndex = 0

private FilterInfoCollection videoDevices

       private VideoCaptureDevice videoSource

       public int selectedDeviceIndex = 0

下面是获取设备

[csharp] view plain copy print?

public FilterInfoCollection GetDevices()

{

try

{

//枚举所有视频输入设备

videoDevices = new FilterInfoCollection(FilterCategory.VideoInputDevice)

if (videoDevices.Count != 纳粗拆0)

{

LogClass.WriteFile("已找到视频设备.")

return videoDevices

}

else

return null

}

catch (Exception ex)

{

LogClass.WriteFile("error:没有找凳旦到视频设备！具体原因：" + ex.Message)

return null

}

}

public FilterInfoCollection GetDevices()

        {

            try

            {

                //枚举所有视频输入设备

                videoDevices = new FilterInfoCollection(FilterCategory.VideoInputDevice)

                if (videoDevices.Count != 0)

                {

                    LogClass.WriteFile("已找到视频设备.")

                    return videoDevices

                }

                else

                    return null

            }

            catch (Exception ex)

            {

                LogClass.WriteFile("error:没有找到视频设备！具体原因：" + ex.Message)

                return null

            }

        }

选择设备，然后连接摄像头

[csharp] view plain copy print?

<p> /// <summary>

/// 连接视频摄像头

/// </summary>

/// <param name="deviceIndex"></param>

/// <param name="resolutionIndex"></param>

/// <returns></returns>

public VideoCaptureDevice VideoConnect(int deviceIndex = 0, int resolutionIndex = 0)

{

if (videoDevices.Count <= 0)

return null

selectedDeviceIndex = deviceIndex

videoSource = new VideoCaptureDevice(videoDevices[deviceIndex].MonikerString)</p><p>            return videoSource

}</p>

<p> /// <summary>

        /// 连接视频摄像头

        /// </summary>

        /// <param name="deviceIndex"></param>

        /// <param name="resolutionIndex"></param>

        /// <returns></returns>

        public VideoCaptureDevice VideoConnect(int deviceIndex = 0, int resolutionIndex = 0)

        {

            if (videoDevices.Count <= 0)

                return null

            selectedDeviceIndex = deviceIndex

            videoSource = new VideoCaptureDevice(videoDevices[deviceIndex].MonikerString)</p><p>            return videoSource

        }</p>

[csharp] view plain copy print?

//抓图，拍照，单帧

public void GrabBitmap(string path)

{

if (videoSource == null)

return

g_Path = path

videoSource.NewFrame += new NewFrameEventHandler(videoSource_NewFrame)

}

//抓图，拍照，单帧

public void GrabBitmap(string path)

       {

           if (videoSource == null)

               return

           g_Path = path

           videoSource.NewFrame += new NewFrameEventHandler(videoSource_NewFrame)

       }

[csharp] view plain copy print?

void videoSource_NewFrame(object sender, AForge.Video.NewFrameEventArgs eventArgs)

{

Bitmap bmp = (Bitmap)eventArgs.Frame.Clone()

string fullPath = path + "temp\\"

if (!Directory.Exists(fullPath))

Directory.CreateDirectory(fullPath)

string img = fullPath + DateTime.Now.ToString("yyyyMMdd hhmmss") + ".bmp"

bmp.Save(img)

void videoSource_NewFrame(object sender, AForge.Video.NewFrameEventArgs eventArgs)

       {

           Bitmap bmp = (Bitmap)eventArgs.Frame.Clone()

           string fullPath = path + "temp\\"

           if (!Directory.Exists(fullPath))

               Directory.CreateDirectory(fullPath)

           string img = fullPath + DateTime.Now.ToString("yyyyMMdd hhmmss") + ".bmp"

           bmp.Save(img)

[csharp] view plain copy print?

//如果这里不写这个，一会儿会不停的拍照，

videoSource.NewFrame -= new NewFrameEventHandler(videoSource_NewFrame)

}

//如果这里不写这个，一会儿会不停的拍照，

           videoSource.NewFrame -= new NewFrameEventHandler(videoSource_NewFrame)

       }

这样就完成了 *** 作摄像头的工作

但是发现一个问题，如果要拍照得到的照片先要处理在保存，这里就有问题了，所以需要在界面前台中添加控件，医用AForge.Controls,然后添加到工具箱，然后将VideoSourcePlayer控件拖到窗体中，想要得到单张图像处理：

Bitmap bmp = videoSourcePlayer1.GetCurrentFrame()

这样就可以拿来处理了，AForge类库是非常的强大，这里只是冰山一角，文章不足之处还请大家多多指正，欢迎提出宝贵意见和建议。谢谢。。。

先移步http://www.aforgenet.com/  下载AForge类库。陵镇

然后引用AForge,AForge.Controls(这个是控件，可以添加到工具箱中),AForge.Imaging,AForge.Video,AForge.Video.DirectShow

public FilterInfoCollection GetDevices()  

        {  

            try  

            {  

                //枚举所有视频输入设备  

                videoDevices = new FilterInfoCollection(FilterCategory.VideoInputDevice)  

                if (videoDevices.Count != 0)  

                {  

                    LogClass.WriteFile("已找到视频设备.")  

                    return videoDevices  

                }  

                else  

                    return null  

            }  

            catch (Exception ex)  

            {  

                LogClass.WriteFile("error:没有找到视频设备！具体原因：" + ex.Message)  

                return null  

            裤悉}  

        }

连接摄像头

 public VideoCaptureDevice VideoConnect(int deviceIndex = 0, int resolutionIndex = 0)  

        {  

            if (videoDevices.Count <= 0)  

                return null  

            selectedDeviceIndex = deviceIndex  

            videoSource = new VideoCaptureDevice(videoDevices[deviceIndex].MonikerString)</p><p>            return videoSource  

        }

拍照

void videoSource_NewFrame(object sender, AForge.Video.NewFrameEventArgs eventArgs)  

        {  

            Bitmap bmp = (Bitmap)eventArgs.Frame.Clone()  

            string fullPath = path + "temp\\"  

      尺纯粗      if (!Directory.Exists(fullPath))  

                Directory.CreateDirectory(fullPath)  

            string img = fullPath + DateTime.Now.ToString("yyyyMMdd hhmmss") + ".bmp"  

            bmp.Save(img)  

            videoSource.NewFrame -= new NewFrameEventHandler(videoSource_NewFrame)  

        }

录像的话调用AForge中的录像函数即可。可以在官网看他的说明文档，很详细。

你好，方法如下：

作为程序员现在应该用的是vs2015，添加依赖项和依赖库和13一样，这里以13为例；

1.首先，打开vs2013和你扰汪备的project

2.要添加依赖项和依赖库，就要找到【解决方案资源管理器】，也许你的【陵运解决方案资源管理器】在右边或左边隐藏，点缓毁开即可

它的快捷键是ctrl+Alt+L
