在opencv 根目录找到opencvroot/samples/gpu/performance/tests.cpp

修改成如下代码。

TEST(ORB)
{
    Mat src = imread(abspath("../data/aloeL.jpg"), IMREAD_GRAYSCALE);
    if (src.empty()) throw runtime_error("can‘t open ../data/aloeL.jpg");

    //ORB orb(4000);
    Ptr<ORB> orb = ORB::create(4000,1.2f,8,31,0,2,ORB::HARRIS_SCORE,31,20);
    vector<KeyPoint> keypoints;
    Mat descriptors;
   
    orb->detectAndCompute(src, Mat(), keypoints, descriptors);

    //orb(src, Mat(), keypoints, descriptors);

    CPU_ON;
    //orb(src, Mat(), keypoints, descriptors);
    orb->detectAndCompute(src, Mat(), keypoints, descriptors);
    CPU_OFF;

    cuda::ORB_CUDA d_orb;
    cuda::GpuMat d_src(src);
    cuda::GpuMat d_keypoints;
    cuda::GpuMat d_descriptors;

    d_orb(d_src, cuda::GpuMat(), d_keypoints, d_descriptors);

    CUDA_ON;
    d_orb(d_src, cuda::GpuMat(), d_keypoints, d_descriptors);
    CUDA_OFF;
}
