大家好 我又来求助了 关键字：c# emgu（opencv）

Question

大家好 初来乍到  最近在研究opencv  刚刚起步 遇到了一些问题 特来求助
我把系统变量等都配置好之后，在工程中也添加了引用
程序如下：using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using Emgu.CV;//PS:调用的Emgu dll  
using Emgu.CV.Structure;
using Emgu.Util;
using System.Threading;namespace WindowsFormsApplication13
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        private Capture capture;
        private bool captureinprocess;//判断摄像头的状态          private void button1_Click(object sender, EventArgs e)
        {
            if (capture != null)//摄像头不为空  
            {
                if (captureinprocess)
                {
                    Application.Idle -= new EventHandler(processfram);
                    button1.Text = "Stop!";
                }
                else
                {
                    Application.Idle += new EventHandler(processfram);
                    button1.Text = "Start!";
                }
                captureinprocess = !captureinprocess;
            }
            else//摄像头为空则通过Capture()方法调用  
            {
                try
                {
                    capture = new Capture();
                }
                catch (NullReferenceException excpt)
                {
                    MessageBox.Show(excpt.Message);
                }
            }
        }        private void processfram(object sender, EventArgs arg)
        {
            Image<Bgr, Byte> frame = capture.QueryFrame();
            imageBox1.Image = frame;
        }
    }
}  
报错的地方为imageBox1.Image = frame;
错与原因如下
错误 1 无法将类型“Emgu.CV.Image<Emgu.CV.Structure.Bgr,byte>”隐式转换为“System.Drawing.Image” C:\Users\Admin\Documents\Visual Studio 2008\Projects\WindowsFormsApplication13\WindowsFormsApplication13\Form1.cs 57 31 WindowsFormsApplication13这该咋整呢？辛苦各位大大~~~

Answer 1

你可以用Image初始化一个BitMap类，Image<Bgr, Byte>有一个构造函数支持BitMap参数初始化，不过最好还只直接给定图片路径初始化。

Answer 2

imageBox1，这个你是声名的还是直接拖到窗体上的，我用过这个例子，可以用，我把我写的发给你，你看看有什么不一样，using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using Emgu.CV;//PS:调用的Emgu dll  
using Emgu.CV.Structure;
using Emgu.Util;
using System.Threading;
using System.Runtime.InteropServices;  
namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        Emgu.CV.UI.ImageBox imageBox1 = new Emgu.CV.UI.ImageBox();
         float xfactor;
         float yfactor;
         Dictionary<string, Rectangle> foundPeople = new Dictionary<string, Rectangle>();
         //[DllImport("facecom.dll")]
                 //public static extern int fnfacecom();
        public Form1()
        {
            InitializeComponent();
        }
          private Capture capture;           
        private bool captureinprocess;//判断摄像头的状态  
  
        private void button1_Click(object sender, EventArgs e)  
        {
            if (capture != null)//摄像头不为空  
            {
                if (captureinprocess)
                {
                    Application.Idle -= new EventHandler(processfram);                    button1.Text = "Stop!";
                }
                else
                {
                    Application.Idle += new EventHandler(processfram);
                    button1.Text = "Start!";
                }
                captureinprocess = !captureinprocess;
            }
            else//摄像头为空则通过Capture()方法调用  
            {
                try
                {
                    capture = new Capture();
                }
                catch (NullReferenceException excpt)
                {
                    MessageBox.Show(excpt.Message);
                }
            }  
        }
        private void processfram(object sender, EventArgs arg)
        {
            Image<Bgr, Byte> frame = capture.QueryFrame();
            imageBox1.Image = frame;        }
        private void Form1_Load(object sender, EventArgs e)
        {
            imageBox1.Size = new Size(this.Size.Height, this.Size.Width);
            imageBox1.BackColor = Color.Black; 
            this.Controls.Add(imageBox1);  
        }
      }
   }  
 
这个是可以用的
