目的：輸出兩臺攝像頭圖像和兩路設(shè)備圖像，每一路設(shè)備截圖6張

主要知識：

1. 通過SDK調(diào)取攝像頭圖像，并對圖像進(jìn)行剪裁；

2. WPF中定時器DispatcherTimer用法；

3.?WPF中跨線程訪問控件方法

? Dispatcher.Invoke((Action)delegate {}）；

區(qū)別于winform中

this.Invoke((Action)delegate {}）；

4.xml操作：

XmlDocument xmlDoc = new XmlDocument();xmlDoc.Load(AppDomain.CurrentDomain.BaseDirectory + "\\config.xml");XmlNode settingNode = xmlDoc.DocumentElement;XmlElement e = settingNode.SelectSingleNode("DeviceType") as XmlElement;if (e == null){deviceType = "tps2000";}else{deviceType = e.InnerText;}

5. 帶多個參數(shù)的委托

DP1 = new DataProcess(DeviceIP1, LocalPort1,0);DP1.ShowEvent1 = DrawControls1;DP1.Start();//啟動線程

6.多線程操作

Thread t1 = new Thread(new ThreadStart(DataRevThread)); //開啟DataRevThreadt1.Name = "DataRevThread"; //線程名字t1.Start();t1.IsBackground = true; //后臺運(yùn)行

7. UDP接收，解碼；

8. emgucv使用；

9. 工廠模式：

ModelFactory?MF?=?new?ModelFactory();DM?=?MF.CreateDataModelFactory_v1(sNeed.ToString());

10.信號量線程間同步

Semaphore TaskSemaphoreData = new Semaphore(0, 2560); //數(shù)據(jù)緩存隊列緩存區(qū)TaskSemaphoreRev.WaitOne(); //等待接收隊列

11.Bitmap轉(zhuǎn)換為ImageSource

[System.Runtime.InteropServices.DllImport("gdi32.dll")]public static extern bool DeleteObject(IntPtr hObject);public static ImageSource ChangeBitmapToImageSource(Bitmap bitmap){IntPtr hBitmap = bitmap.GetHbitmap();ImageSource wpfBitmap = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(hBitmap,IntPtr.Zero,Int32Rect.Empty,BitmapSizeOptions.FromEmptyOptions());if (!DeleteObject(hBitmap)){throw new System.ComponentModel.Win32Exception();}return wpfBitmap;}

12.Queue和list的操作

包括但是不限于以上內(nèi)容

代碼如下：
