如何在Vb.Net中旋转使用DirectX获取的摄像机视图？ [英] How do I rotate a camera view got with DirectX in Vb.Net ?

问题描述

大家好。



我正在用相机做点什么。我使用DirectX.Capture和DShowNET库来查看我的相机视图到一个图片框。我的问题是我需要在视图处于正确位置之前将我的摄像机视图旋转270°。



我在很多帖子中搜索过这个问题，但没有。在Vb.Net或甚至在C＃中曾经有人这样做过吗？如果是的话，你能帮我找一个解决方案吗？



感谢您的帮助。

Hi Everybody.

I'm working on something with a camera. I use DirectX.Capture and DShowNET libraries to look at my camera view into a picturebox. My problem is that i need to rotate my camera view at 270° before the view is in a correct position.

I've searched for that matter in a lot of posts but nothing. Is is someone here who has ever done it in Vb.Net or even in C# ? If yes, could you please help me to find a solution ?

Thanks for your help.

推荐答案

Brian Low和Blas5写了关于DirectX.Capture类的文章图书馆。

DirectX.Capture类库 [ ^ ]

您可以向他们发送关于您的请求的PM。

Brian Low and Blas5 wrote articles about the DirectX.Capture Class Library.

You can maybe send them a PM about your request.

这是我最终找到的。不完美，但它有一段时间对我有帮助。

Public Class Prise_Image



'仅供流媒体使用

Dim Camera As DirectX.Capture.Filter

Dim CaptureInfo作为DirectX.Capture.Capture

Dim CamContainer As DirectX.Capture.Filters = New DirectX.Capture.Filters（）

Dim CaptureImage As Image



Private Sub Prise_Image_FormClosed（ByVal sender） As Object，ByVal e As System.Windows.Forms.FormClosedEventArgs）Handles Me.FormClosed

CaptureInfo.Stop（）

End Sub



Private Sub Prise_Image_Load（ByVal sender As Object，ByVal e As System.EventArgs）Handles Me.Load

'Activation delavidéo

Initialiser_Streaming_Camera（ ）

End Sub



Private Sub Initiali ser_Streaming_Camera（）

Dim nb_of_cam As Integer = CamContainer.VideoInputDevices.Count

For i As Integer = 0 to nb_of_cam

试试

Camera = CamContainer.VideoInputDevices（i）'获取视频输入设备

CaptureInfo = New DirectX.Capture.Capture（Camera，Nothing）'使用视频输入设备初始化Capture

CaptureInfo.PreviewWindow = Me.Pic_Pic'设置输入视频预览窗口（这里是一个图片框）

'ActureInfo.FrameRate = 29.997'设置输入视频率

'ActureInfo.FrameSize =新尺寸（640,480）'设置输入视频尺寸

CaptureInfo.Start（）

Catch ex As Exception

结束尝试
