运行简单的opencv cuda程序需要哪个opencv cuda库？

标签： c++ visual-studio-2010 opencv

我在win7 x64上使用visual studio 2010构建了opencv with cuda支持。为了运行一个简单的opencv cuda程序，我编写了这段代码，并将输出释放的exe文件放在所有lib和dll文件附近的opencv\built\install\x64\vc10\bin。

但是当我运行exe文件时会产生错误No CUDA support (The library is compiled without CUDA support)

这是我的代码：

#include <opencv2/opencv.hpp>
#include <iostream>
#include <string>
#include <chrono>
#include <ctime>
#include <opencv2/core/cuda.hpp>

using namespace cv;
using namespace cv::cuda;
using namespace std;

string source_image_addr, gray_image_addr="", source_image_name="";

int convert2gray()
{
    Mat image;
    GpuMat d_image, d_gray_image;
    image = imread((char *)source_image_addr.c_str(), IMREAD_COLOR);

    if(image.empty())
    {
        cout<<"Could not open or find the image"<<std::endl;
        return -1;
    }

    CV_Assert(image.depth() != sizeof(unsigned char));
    std::chrono::time_point<chrono::system_clock> start, end;
    start = chrono::system_clock::now();
    d_image.upload(image);
    cuda::cvtColor(d_image, d_gray_image, CV_RGB2GRAY);
    Mat gray_image(d_gray_image);
    end = chrono::system_clock::now();
    chrono::duration<double> elapsed = end - start;
    cout<<"for image["<<image.cols<<"*"<<image.rows<<"] elapsed = "<<elapsed.count()<<endl;

    //namedWindow("Gray Window", WINDOW_AUTOSIZE);
    //imshow("Gray Window", gray_image);
    imwrite((char *)gray_image_addr.c_str(), gray_image);
}

int main(int argc, char** argv)
{
    if(argc >= 2)
    {
        source_image_addr = argv[1];
        source_image_name = source_image_addr.substr(0, source_image_addr.find_last_of("."));

        if(argc >= 3)
            gray_image_addr = argv[2];
        else
            gray_image_addr = source_image_name + "-gray.jpg";

        if(!convert2gray())
            return -1;
    }
    else
    {
        cout<<"Usage: convert2gray ImageAddress [gray_image_addr]"<<endl;
        return -1;
    }

    //waitKey(0);
    return 0;
}

我已将opencv_world300.dll放在同一个文件夹中。

修改 以下是std::cout << cv::getBuildInformation() << std::endl;：

OpenCV预编译二进制文件在没有cuda / GPU支持的情况下进行编译（错误消息告诉您的内容也是＆gt;＆gt; openCV未经cuda支持编译）。

你必须编译自己的OpenCV（使用CMake很容易完成）来获得cuda支持（激活08-05 18:13:33.711 12931-12931/com.example.ido.grades E/CliptrayUtils﹕ hideClipTrayIfNeeded() TextView is focused!! hideClipTray() 08-05 18:13:35.157 343-433/?

看看： http://docs.opencv.org/doc/tutorials/introduction/windows_install/windows_install.html#installation-by-making-your-own-libraries-from-the-source-files

您可能还需要照顾不同的cuda平台： http://docs.opencv.org/modules/gpu/doc/introduction.html

使用WITH_CUDA=ON您可以在运行时打印OpenCV构建设置，如果您不确定如何编译库。
