OpenCV GpuMat 用法

Question

我正在尝试使用 OpenCV GpuMat，但出现断言错误，我的代码如下

#include "opencv2/opencv.hpp"
#include "opencv2/imgproc/imgproc.hpp"
#include "opencv2/highgui/highgui.hpp"
#include "opencv2/gpu/gpu.hpp"

// ...

using namespace cv;
using namespace cv::gpu;

int main()
{
    string baboon = "baboon.jpg";
    try
    {
        DeviceInfo info = getDevice();
        cout << info.name() << endl;

        GpuMat src;

        src = cv::imread(baboon, 1);
    }
    catch (const cv::Exception* ex)
    {
        cout << "Error: " << ex->what() << endl;
    }
}

输出是:

GeForce GTX 550 Ti
OpenCV Error: Assertion failed (!m.empty()) in unknown function, file ($PATH_TO_OPENCV)\opencv\modules\gpu\src\gpumat.cpp, line 411

关于如何解决这个问题有什么想法吗？

Answer 1

解决方法是:

Mat src;

src = cv::imread("...");

GpuMat dst;

dst.upload(src);
