将Emgucv与VisualStudio 2019配合使用时，没有Emgucv ImageBox

Question

在通过NuGet包管理器安装Emgucv.runtime.windows之后，我找不到Emgucv ImageBox。我也尝试过在.NET框架组件列表中查找Emgucv dll文件作为可能的解决办法，但失败了(可以通过右键单击‘选择项目...’找到)。在通用工具箱下)。

我正在尝试使用VB.net访问我的网络摄像头，需要显示图像帧，最好是在Emgucv ImageBox中，而不是标准的.NET框架PictureBox中。

有没有找不到Emgucv ImageBox的原因？

下面是我的代码片段：

Public Class Form1

    Dim imageCapture As Emgu.CV.VideoCapture = New Emgu.CV.VideoCapture
    Dim image_mat As Mat = New Mat
    Dim img As Emgu.CV.Image(Of Bgr, Byte)

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

    End Sub

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

        REM things get messy here.... 
        image_mat = Me.imageCapture.QueryFrame
        img = image_mat.ToImage(Of Bgr, Byte)

        REM I want to convert img into a compatible data type for the PictureBox1.Image since I do not have the Emgucv ImageBox

    End Sub
End Class

此解决方案是使用imageBox工具的替代方案。在Nuget Package Manager中，有一个额外的Emgu框架，用于将Emgu.CV.Mat数据类型转换为位图-它被称为Emgu.CV.Bitmap。

Imports Emgu.CV
Imports Emgu.CV.Structure

Public Class Form1

    Dim imageCapture As Emgu.CV.VideoCapture = New Emgu.CV.VideoCapture
    Dim image_mat As Emgu.CV.Mat = New Emgu.CV.Mat
    Dim img As Emgu.CV.Image(Of Bgr, Byte)

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

        image_mat = Me.imageCapture.QueryFrame
        img = image_mat.ToImage(Of Bgr, Byte)
        PictureBox1.Image = img.ToBitmap REM <---------

    End Sub
End Class
