在Winform中集成摄像头功能,你可以使用DirectShow.NET
库来捕获视频流。以下是一个简单的示例,展示了如何在Winform应用程序中集成摄像头功能:
DirectShow.NET
库。如果没有安装,可以通过NuGet包管理器安装:Install-Package DirectShowLib
VideoCapture
类,用于处理摄像头的捕获工作:using System;
using System.Drawing;
using System.Windows.Forms;
using DirectShowLib;
public class VideoCapture : Form
{
private IGraphBuilder _graphBuilder;
private IMediaControl _mediaControl;
private IMediaSeeking _mediaSeeking;
private IVideoWindow _videoWindow;
private ICaptureGraphBuilder2 _captureGraphBuilder;
private IBaseFilter _cameraFilter;
private VideoCaptureForm _form;
public VideoCapture()
{
InitializeComponent();
}
public static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new VideoCapture());
}
private void InitializeComponent()
{
this._form = new VideoCaptureForm();
this._graphBuilder = (IGraphBuilder)new FilterGraph();
this._mediaControl = (IMediaControl)this._graphBuilder;
this._mediaSeeking = (IMediaSeeking)this._graphBuilder;
this._videoWindow = (IVideoWindow)this._graphBuilder;
this._captureGraphBuilder = (ICaptureGraphBuilder2)this._graphBuilder;
this._cameraFilter = (IBaseFilter)new CameraFilter();
this._form.SuspendLayout();
//
// VideoCapture
//
this._form.ClientSize = new System.Drawing.Size(640, 480);
this._form.Name = "VideoCapture";
this._form.Load += new System.EventHandler(this._form_Load);
this._form.ResumeLayout(false);
}
private void _form_Load(object sender, EventArgs e)
{
ConfigureGraph();
_mediaControl.Run();
}
private void ConfigureGraph()
{
// Add the camera filter to the graph
_captureGraphBuilder.RenderFile("C:\\path\\to\\your\\camera\\driver\\sample.avi", null);
_captureGraphBuilder.AddFilterToInput(null, _cameraFilter);
// Set the output window
_videoWindow.Owner = this;
_videoWindow.WindowStyle = FormWindowStyle.AutoSize;
_videoWindow.SetWindowPosition(0, 0, this.ClientSize.Width, this.ClientSize.Height);
_videoWindow.Visible = true;
// Connect the camera filter to the output
_captureGraphBuilder.Connect(_cameraFilter, null, null);
// Render the graph
_mediaControl.Render();
}
}
VideoCaptureForm
类中,添加一个PictureBox
用于显示摄像头的视频流:public partial class VideoCaptureForm : Form
{
private PictureBox _pictureBox;
public VideoCaptureForm()
{
InitializeComponent();
_pictureBox = new PictureBox();
this.Controls.Add(_pictureBox);
_pictureBox.Dock = DockStyle.Fill;
}
}
ConfigureGraph
方法中,将捕获到的视频流设置为PictureBox
的图像:private void ConfigureGraph()
{
// ... 其他代码 ...
// Set the output window
_videoWindow.Owner = this;
_videoWindow.WindowStyle = FormWindowStyle.AutoSize;
_videoWindow.SetWindowPosition(0, 0, this.ClientSize.Width, this.ClientSize.Height);
_videoWindow.Visible = true;
// Connect the camera filter to the output
_captureGraphBuilder.Connect(_cameraFilter, null, null);
// Render the graph
_mediaControl.Render();
// Set the video stream to the PictureBox
_pictureBox.Image = new Bitmap(_form.ClientSize.Width, _form.ClientSize.Height);
_mediaControl.GetCurrentImage(new Rectangle(0, 0, _form.ClientSize.Width, _form.ClientSize.Height), _pictureBox.Image);
}
现在,当你运行Winform应用程序时,它将显示摄像头的实时视频流。请注意,这个示例仅适用于特定的摄像头驱动程序,你可能需要根据你的摄像头型号和驱动程序进行调整。
