贴入下面代码，我在win7 vs2008 VB.net 下运行顺利

Imports Emgu.CV
Imports Emgu.CV.CvEnum
Imports Emgu.CV.Structure

Public Class Form1

Private Sub Form1_Load(sender As System.Object,e As System.EventArgs) Handles MyBase.Load
'The name of the window
Dim win1 = "Test Window"

'Create the window using the specific name
CvInvoke.cvNamedWindow(win1)

'Create an image of 400x200 of Blue color
Using img As Image(Of Bgr,Byte) = New Image(Of Bgr,Byte)(400,200,New Bgr(255,0))

'Create the font
Dim f = New MCvFont(Emgu.CV.CvEnum.FONT.CV_FONT_HERSHEY_COMPLEX,1.0,1.0)
'Draw "Hello,world." on the image using the specific font
img.Draw("Hello,world",f,New Point(10,80),New Bgr(0,255,0))

'Show the image
CvInvoke.cvShowImage(win1,img.Ptr)
'Wait for the key pressing event
CvInvoke.cvWaitKey(0)
'Destory the window
CvInvoke.cvDestroyWindow(win1)
End Using
End Sub
End Class

不过目前想尝试使用VB自带的picBox控件加载图片，使用cvinvoke的方法处理时，会提示类型不同。正在解决中

附emgu函数说明

Function Mapping - Emgu.CV.CvInvoke

The CvInvoke class provides a way to directly invokeOpenCVfunction within .NET languages. Each method in this class corresponds to a function inOpenCVof the same name. For example,a call to

 IntPtr image = CvInvoke.cvCreateImage(new System.DrawingSize(400,300),CvEnumIPL_DEPTHIPL_DEPTH_8U,0)">1);

 IplImage* image = cvCreateImage(cvSize(@H_403_112@400, @H_403_112@300)1;

Both of which create a 400x300 of 8-bit unsigned grayscale image.

Structure Mapping - Emgu.CV.Structure.Mxxx

This type of structure is a direct mapping toOpenCVstructures.

The prefixMhere stands for Managed structure.

Emgu CValso borrows some existing structures in .Net to represent structures inOpenCV:

Enumeration Mapping - Emgu.CV.CvEnum

The CvEnum namespace provides direct mapping toOpenCVenumerations. For example,CvEnum.IPL_DEPTH.IPL_DEPTH_8Uhas the same value asIPL_DEPTH_8UinOpenCV; both of which equals8.
