Преобразование изображений из Pylon в Opencv на С++

Я хочу преобразовать стереоизображения, снятые камерами Basler, в формат opencv (Mat). В приведенном ниже коде я преобразовал изображения в формат opencv, но на этапах показа я не могу показать изображения. пожалуйста, направьте меня. Спасибо

int main(int argc, char* argv[])
{
    // The exit code of the sample application.
    int exitCode = 0;


    PylonInitialize();
    Pylon::PylonAutoInitTerm autoInitTerm;//me

    try
    {
        // Get the transport layer factory.
        CTlFactory& tlFactory = CTlFactory::GetInstance();

        // Get all attached devices and exit application if no device is found.
        DeviceInfoList_t devices;
        if (tlFactory.EnumerateDevices(devices) == 0)
        {
            throw RUNTIME_EXCEPTION("No camera present.");
        }

        CInstantCameraArray cameras(min(devices.size(), c_maxCamerasToUse));

        // Create and attach all Pylon Devices.
        for (size_t i = 0; i < cameras.GetSize(); ++i)
        {
            cameras[i].Attach(tlFactory.CreateDevice(devices[i]));

            // Print the model name of the camera.
            cout << "Using device " << cameras[i].GetDeviceInfo().GetModelName() << endl;
        }


        CGrabResultPtr ptrGrabResult;
        CImageFormatConverter formatConverter;//me
        formatConverter.OutputPixelFormat = PixelType_BGR8packed;//me
        CPylonImage pylonImage;//me

        // Create an OpenCV image
        Mat openCvImage;//me
    for (int i = 0; i < c_countOfImagesToGrab && cameras.IsGrabbing(); ++i)
        {
            cameras.RetrieveResult(5000, ptrGrabResult, TimeoutHandling_ThrowException);

            intptr_t cameraContextValue = ptrGrabResult->GetCameraContext();
