Question

所以我要做的是输出一个字符串，具体取决于我在视频Feed中看到的颜色。就目前而言，我所做的就是确定Feed的阈值，使高于某个亮度的所有内容都显示为红色。现在我想要一些东西，说明如果Feed中有任何红色，那么我会在我的用户界面上显示Feed的文本框中输出“1”。如果没有红色，则输出“0”到文本框。我在VS2010上使用Emgu CV Managed C ++，任何人都可以帮助我吗？谢谢。

这是我到目前为止无法正常工作的代码，它给了我一个编译器错误。

cvConvertScaleAbs(frameFromCamera->Ptr.ToPointer(),frameDisplay->Ptr.ToPointer(),double(1)/16,0);
    cvCvtColor(frameDisplay->Ptr.ToPointer(),frameColorDisplay->Ptr.ToPointer(),CV_GRAY2BGR);
    cvThreshold(frameDisplay->Ptr.ToPointer(),maskSaturated->Ptr.ToPointer(),200,255,CV_THRESH_BINARY);
    cvNot(maskSaturated->Ptr.ToPointer(),mask1->Ptr.ToPointer());
    cv::Scalar red(0,0,255);
    cvSet(frameColorDisplay->Ptr.ToPointer(),red,maskSaturated->Ptr.ToPointer());

    highColor = gcnew Emgu::CV::Image<Bgr,UInt16>(0, 0, 255);
    lowColor = gcnew Emgu::CV::Image<Bgr,UInt16>(0, 0, 200);

    if(maskSaturated->InRange(lowColor, highColor) == 255){
        tbMorse->Text ="1";
    }
    else{
        tbMorse->Text = "0";
    }
    imageMain->Image=frameColorDisplay;

我在我的标题中初始化了highColor和lowColor

Emgu::CV::Image<Bgr,UInt16> ^lowColor;
    Emgu::CV::Image<Bgr,UInt16> ^highColor;

并且它给我的错误是

 BAOTFISInterface.cpp(1010): error C2664: 'Emgu::CV::Image<TColor,TDepth>::Image(int,int,Emgu::CV::Structure::Bgr)' : cannot convert parameter 3 from 'int' to 'Emgu::CV::Structure::Bgr'

根据视频输入中检测到的颜色输出字符串
