我正在使用C#开发一个实时计算机视觉应用程序。但我无法优化Emgucv解码。从地面实况到600毫秒延迟,从Ip摄像头提供商应用程序轴到600毫秒延迟。
如何优化延迟最多为250毫秒的代码?
下面是抓取图像的代码。
capture1 = new Capture(IpFirstCamTxt.Text); //create a camera captue from RTSP Stream
capture2 = new Capture(Ip2ndCamTxt.Text);
capture3 = new Capture(Ip3rdCamTxt.Text);
capture4 = new Capture(Ip4thCamTxt.Text);
capture1.Start();
capture2.Start();
capture3.Start();
capture4.Start();
capture1.ImageGrabbed += ProcessFrame1;
capture2.ImageGrabbed += ProcessFrame2;
capture3.ImageGrabbed += ProcessFrame3;
capture4.ImageGrabbed += ProcessFrame4;
private void ProcessFrame1(object sender, EventArgs arg)
{
_capture.RetrieveBgrFrame().ToBitmap());
capture1.Retrieve(img1, 3);
pictureBox1.Image = img1.ToBitmap();
}
private void ProcessFrame2(object sender, EventArgs arg)
{
capture2.Retrieve(img2, 3);
pictureBox3.Image = img2.ToBitmap();
}
private void ProcessFrame3(object sender, EventArgs arg)
{
capture3.Retrieve(img3, 3);
pictureBox4.Image = img3.ToBitmap();
}
private void ProcessFrame4(object sender, EventArgs arg)
{
capture4.Retrieve(img4, 3);
pictureBox5.Image = img4.ToBitmap();
}
我的应用程序与camera provider应用程序的秒表结果比较:
