我正在关注这个视频，一切顺利。但是失败了＆＃34; capturez.QueryFrame＆＃34;

＆＃13;

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

＆＃13;

Answer 1

vb。中没有Retrieve()方法。

尝试将capturez.Retrieve()替换为capturez.QueryFrame()或Capturez.RetrieveBgrFrame()。

如果你已经改变了但是你在capturez.QueryFrame失败了，那就意味着你在x86（bin / debug）中缺少一些dll文件。
