C# 使用AForge调用笔记本摄像头拍照

vs2012 winform

连接摄像头设备，这里需要引入

代码：

using AForge;
using AForge.Controls;
using AForge.Imaging;
using AForge.Video;
using AForge.Video.DirectShow;

在工具箱中还需要添加AForge.Control，然后找到VideoSourcePlayer这个控件添加到界面上

直接找到dll拖拽到工具箱就可以了（工具箱先建一个选项）

将在camera里面出现很多控件，找到videoSourcePlayer，拖拽至form窗体

然后完成了基本设置

定义全局变量

FilterInfoCollection videoDevices;
VideoCaptureDevice videoSource;
public int selectedDeviceIndex = 0;

然后连接摄像头

 1 private void btn_getdevice_Click(object sender, EventArgs e)
 2         {
 3             videoDevices = new FilterInfoCollection(FilterCategory.VideoInputDevice);
 4             selectedDeviceIndex = 0;
 5             videoSource = new VideoCaptureDevice(videoDevices[selectedDeviceIndex].MonikerString);//连接摄像头。
 6             videoSource.VideoResolution = videoSource.VideoCapabilities[selectedDeviceIndex];
 7             videoSourcePlayer1.VideoSource = videoSource;
 8             // set NewFrame event handler
 9             videoSourcePlayer1.Start();  
10         }

拍照：

1  private void button1_Click(object sender, EventArgs e)
2         {
3             if (videoSource == null)
4                 return;
5             Bitmap bitmap = videoSourcePlayer1.GetCurrentVideoFrame();
6             string fileName = "54250.jpg";//DateTime.Now.ToString("yyyy-MM-dd-HH-mm-ss-ff") + ".jpg";
7             bitmap.Save(@"E:	emp" + fileName, ImageFormat.Jpeg);
8             bitmap.Dispose();
9         }
