C# 使用AForge調用筆記本攝像頭拍照

vs2012  winform

連接攝像頭設備，這里需要引入

代碼：

 

 

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

在工具箱中還需要添加AForge.Control，然后找到VideoSourcePlayer這個控件添加到界面上

直接找到dll拖拽到工具箱就可以了（工具箱先建一個選項）

將在camera里面出現很多控件，找到videoSourcePlayer，拖拽至form窗體

 

 

然后完成了基本設置

定義全局變量

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

然后連接攝像頭

private void btn_getdevice_Click(object sender, EventArgs e)
        {
            videoDevices = new FilterInfoCollection(FilterCategory.VideoInputDevice);
            selectedDeviceIndex = 0;
            videoSource = new VideoCaptureDevice(videoDevices[selectedDeviceIndex].MonikerString);//連接攝像頭。
            videoSource.VideoResolution = videoSource.VideoCapabilities[selectedDeviceIndex];
            videoSourcePlayer1.VideoSource = videoSource;
            // set NewFrame event handler
            videoSourcePlayer1.Start();  
        }      

 

拍照：

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

 

 

 

這樣就完成了拍照功能
