libargus获取图像转化为MAt

好的，针对您的问题，我可以给出以下代码示例来演示如何使用libargus获取图像并将其转化为OpenCV中的Mat格式：

#include <Argus/Argus.h>
#include <EGLStream/EGLStream.h>
#include <opencv2/opencv.hpp>

using namespace Argus;
using namespace EGLStream;

int main(int argc, char** argv)
{
    // 初始化Argus和EGLStream
    UniqueObj<CameraProvider> cameraProvider(CameraProvider::create());
    ICameraProperties *iCameraProp = interface_cast<ICameraProperties>(cameraProvider);
    iCameraProp->setBaseSensorMode(0);
    UniqueObj<CameraDevice> cameraDevice(cameraProvider->getCameraDevice());
    UniqueObj<OutputStreamSettings> streamSettings(cameraDevice->createOutputStreamSettings());
    streamSettings->setPixelFormat(PIXEL_FMT_YCbCr_420_888);
    streamSettings->setResolution(Size2D<uint32_t>(640, 480));
    streamSettings->setEGLDisplay(EGL_DEFAULT_DISPLAY);
    UniqueObj<OutputStream> outputStream(cameraDevice->createOutputStream(streamSettings.get()));

    // 创建EGLStream连接
    EGLDisplay eglDisplay = EGL_DEFAULT_DISPLAY;
    UniqueObj<EGLStream::FrameConsumer> consumer(FrameConsumer::create(eglDisplay, outputStream.get()));
    UniqueObj<EGLStream::Frame> frame(consumer->acquireFrame());
    NV::EGLStreamImage *streamImage = interface_cast<NV::EGLStreamImage>(frame->getImage());
    if (!streamImage) {
        std::cerr << "Failed to get EGLStreamImage" << std::endl;
        return -1;
    }

    // 将EGLStreamImage转换为OpenCV的Mat
    EGLImageKHR eglImage = streamImage->getEGLImage();
    cv::Mat img(streamImage->getHeight(), streamImage->getWidth(), CV_8UC3);
    EGLDisplay eglDisplay = eglGetDisplay(EGL_DEFAULT_DISPLAY);
    EGLContext eglContext = eglGetCurrentContext();
    if (!cv::cvtColor(eglImage, img, cv::COLOR_YUV2BGR_NV12)) {
        std::cerr << "Failed to convert YUV to BGR" << std::endl;
        return -1;
    }

    // 显示图像
    cv::imshow("image", img);
    cv::waitKey(0);

    return 0;
}

此示例代码演示了如何使用libargus从相机设备中获取图像，并将其转换为OpenCV的Mat格式，以便进行后续的图像处理。注意，此示例需要安装libargus和EGLStream，并且需要在编译时链接这些库。
