推荐答案

我不知道您使用的是哪个库，甚至我也不知道不知道linkprite相机是什么意思，但是请尝试使用此框架来处理相机或摄像机: http://www.aforgenet.com/framework/ [ ^ ]

我正在使用摄像机，请尝试以下操作:

I don''t know what library do you use and even I don''t know what linksprite camera means, but try this framework for working with cameras or video cameras: http://www.aforgenet.com/framework/[^]

I was working with video cameras, try this:

public class CameraImaging
    {
        // enumerate video devices
        public FilterInfoCollection videoDevices = new FilterInfoCollection(FilterCategory.VideoInputDevice );
        //camera
        private VideoCaptureDevice _videoSource;
        public Bitmap bitmap = new Bitmap(10, 10);
        public VideoCaptureDevice videoSource
        {
            get
            {
                return _videoSource;
            }
            set
            {
                _videoSource = value;
                // set NewFrame event handler
                _videoSource.NewFrame +=new NewFrameEventHandler(videoSource_NewFrame);
            }
        }
        //screen shot
        
        public CameraImaging(VideoCaptureDevice videoDevice)
        {
            // create video source
            VideoCaptureDevice videoSource = videoDevice;
        }
        public CameraImaging()
        {

        }
        private void videoSource_NewFrame( object sender, NewFrameEventArgs eventArgs )
        {
            // get new frame
            lock (bitmap)
            {
                bitmap = (Bitmap)eventArgs.Frame.Clone();
                // process the frame
            }
            
        }
    }

并在MainForm中运行视频...这将生成一个图像(位图):

and run the video in MainForm... this will make one image (bitmap):

camImg.videoSource.Start();
lock (mImageLock)
{
    Bitmap tmp = (Bitmap)camImg.bitmap.Clone();

    if (InvokeRequired)
    {
        BeginInvoke(new MethodInvoker(() =>
        {
            pictureBox1.Image = tmp;
            pictureBox1.Invalidate();
        }));
    }
    else
    {
        pictureBox1.Image = tmp;
        pictureBox1.Invalidate();
    }
}
camImg.Video.Stop();
