我下面这个西元，一切进展顺利。但 “capturez.QueryFrame” 失败

Imports Emgu.CV 
 
Imports Emgu.CV.Util 
 
Imports Emgu.CV.Structure 
 

 
Public Class Form1 
 

 
    Dim capturez As Capture = New Capture 
 

 
    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick 
 

 
     Dim imagez As Image(Of Bgr, Byte) = capturez.Retrieve() 'Instead of QueryFrame, you may need to do RetrieveBgrFrame depending on the version of EmguCV you download. 
 

 
     PictureBox1.Image = imagez.ToBitmap() 
 

 
    End Sub 
 
End Class

Answer 1

有一个在VB中没有Retrieve()方法。

尝试用capturez.QueryFrame()或Capturez.RetrieveBgrFrame()代替capturez.Retrieve()。

如果你已经改变了，但你在capturez.QueryFrame上失败，这意味着你错过了x86（bin/debug）中的一些dll文件。
