我製作的項目可以使用Visual Studio C#在帶有bootcamp的Macbook pro上使用Aforge框架跟蹤對象。問題是當我運行代碼並關閉它時。然後重新運行它,代碼將不再在我的相機上顯示圖像。另外,在代碼停止後,我的攝像頭上的綠燈仍然亮着。Macbook相機不會關閉,並有一個小小的C#aforge問題
我的第二個問題是,當我點擊「跟蹤對象按鈕」並將濾鏡應用於圖像時,由於某些原因,它將濾鏡應用於兩個圖片框而不是一個。我需要幫助調試我的代碼。我嘗試重新安排應用過濾器的線條,但我似乎無法做到正確。
這裏是我的代碼
namespace VideoProcessing1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
Graphics g;
Bitmap video;
bool OnOff;
int mode;
int thoigianddemnguoc;
private FilterInfoCollection CaptureDevice;
private VideoCaptureDevice FinalFrame;
private void Form1_Load(object sender, EventArgs e)
{
CaptureDevice = new FilterInfoCollection(FilterCategory.VideoInputDevice);
foreach (FilterInfo Device in CaptureDevice)
{
comboBox1.Items.Add(Device.Name);
}
comboBox1.SelectedIndex = 0;
FinalFrame = new VideoCaptureDevice();
//FinalFrame.Stop();
}
private void button1_Click(object sender, EventArgs e)
{
FinalFrame = new VideoCaptureDevice(CaptureDevice[comboBox1.SelectedIndex].MonikerString);
FinalFrame.NewFrame += new NewFrameEventHandler(FinalFrame_NewFrame);
FinalFrame.Start();
}
void FinalFrame_NewFrame(object sender, NewFrameEventArgs eventArgs)
{
video = (Bitmap)eventArgs.Frame.Clone();
Bitmap video2 = (Bitmap)eventArgs.Frame.Clone();
g = Graphics.FromImage(video2);
g.DrawString("Test", new Font("Arial", 20), new SolidBrush(Color.White), new PointF(2, 2));
g.Dispose();
if (mode == 1)
{
ColorFiltering colorfilter = new ColorFiltering();
colorfilter.Red = new AForge.IntRange(0, 255);
colorfilter.Green = new AForge.IntRange(0, 75);
colorfilter.Green = new AForge.IntRange(0, 75);
colorfilter.ApplyInPlace(video2);
BlobCounter blobcounter = new BlobCounter();
blobcounter.MinHeight = 20;
blobcounter.MaxWidth = 20;
blobcounter.ObjectsOrder = ObjectsOrder.Size;
blobcounter.ProcessImage(video2);
Rectangle[] rect = blobcounter.GetObjectsRectangles();
if (rect.Length > 0)
{
Rectangle objec = rect[0];
Graphics graphic = Graphics.FromImage(video2);
using (Pen pen = new Pen(Color.White, 3))
{
graphic.DrawRectangle(pen, objec);
}
graphic.Dispose();
}
pictureBox2.Image = video2;
}
pictureBox1.Image = video2;
}
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
if(FinalFrame.IsRunning==true)
{
FinalFrame.Stop();
}
}
private void button2_Click(object sender, EventArgs e)
{
pictureBox2.Image = (Bitmap)pictureBox1.Image.Clone();
}
private void button3_Click(object sender, EventArgs e)
{
mode = 1;
}
}
}
感謝您的回覆。我仍然無法關閉相機。我使用了你建議的代碼,甚至爲此目的添加了一個按鈕,但無濟於事。 – rorivy15
