使用Aforge 开发的摄像头,有拍照，录像，设置帧率,分辨率等，以及对视频以及相机等的控制

先上图，这是整个功能的界面: （这里就连了两个相机，如果想连接上百个，这里提一句超级优化的方向，大家可以使用双缓冲概念(是不是很懵？)，其实说白了，就是多幅位图绘制到一张位图上显示. 以前也是做实时绘制的时候，不知不觉就使用这种方式，直到后来，才听到双缓冲这个看似“高大上的”概念，真是倒腾概念.?)

首先声明，里面应该使用线程的方式，大家记得重新封装,代替里面的DispatcherTimer 。好，废话不多说，我们开始.

一：大家下载Aforge等的 dll ---> 添加到引用里面.（在我的资源里有，这个也是我调试了很多dll版本，才发现这个版本很稳定，其他dll版本，一言难尽）

，

在后台代码里，引入dll所在的命名空间.

using AForge.Video;
using AForge.Video.DirectShow;

using AForge.Video.FFMPEG;

二：环境搭载完成后，我们来看xaml文件.

因为这个Aforge，貌似只放在winform空间里，为了不使用那个winformhost，我们就创建两个 form 中的自定义控件，来承载AForge上传过来的视频图像.（反正两种方式都可以，就是宿主窗口，这里为了省事.）

上面两个userControl2.cs，都只是一个form控件.

我们来看其后台代码：

namespace WP_摄像头AFore版本
{public partial class UserControl2 : UserControl{public UserControl2(){InitializeComponent();}public AForge.Controls.VideoSourcePlayer getvideoSourcePlayer2{get{return videoSourcePlayer2;}set{videoSourcePlayer2 = value;}}}
}/这里式usercontrol1() 的后台代码
namespace WP_摄像头AFore版本
{public partial class UserControl11 : UserControl{public UserControl11(){InitializeComponent();//  rotateTransform = new RotateTransform(180, getvideoSourcePlayer1.Width / 2, getvideoSourcePlayer1.Height / 2);//180度}//  public RotateTransform rotateTransform;public AForge.Controls.VideoSourcePlayer getvideoSourcePlayer1{get{return videoSourcePlayer1;}set{videoSourcePlayer1 = value;}}}
}

准备工作完成之后，我们来看主界面功能的实现: 注意啊：下面代码太长了，我没有整理，大家就对应着前面的xaml界面中的功能，自己选择 ....

// 上面代码太多，见谅，大家从里面选择一些自己需要的功能，自己调试.

//这是拍照功能.

//这是录像

以上就是这个摄像头的操作，里面可优化的空间很大,这个就是摄像头涉及到的基本功能显示，很原始。

对了，提一句：你可以对这个摄像头采集到的图像，使用AForge做各种图像上的处理，比如高斯模糊，提取边缘，什么膨胀，腐蚀，提取交点啊等等(里面对图像的处理接口，我也已经写好了哈，大伙儿直接处理那个bitmap就行了)，反正opencv里面可以做的，你在这里都可以处理，这样就实现了我们视频上各种特效...我这里只是提了个引子，之前这些图像都处理过，一口气写了几十个，有机会，给大家分享这些

如果大家优化了更好的，可以@我，我也学习一下.?
