我正在尝试实现OpenCV 3.0.0 SURF功能描述和检测,但在OpenCV站点上运行示例代码后,我收到所有与SURF相关的错误.什么可能出错？谢谢!

#include <stdio.h>
#include <iostream>
#include "opencv2/core.hpp"
#include "opencv2/features2d.hpp"
#include "opencv2/highgui.hpp"
#include "opencv2/calib3d.hpp"
#include "opencv2/xfeatures2d.hpp"
#include <opencv2/nonfree/nonfree.hpp>

using namespace cv;
using namespace cv::xfeatures2d;

void readme();

/** @function main */
int main(int argc, char** argv)
{
    if (argc != 3)
    {
        readme(); return -1;
    }

    Mat img_object = imread(argv[1], IMREAD_GRAYSCALE);
    Mat img_scene = imread(argv[2], IMREAD_GRAYSCALE);

    if (!img_object.data || !img_scene.data)
    {
        std::cout << " --(!) Error reading images " << std::endl; return -1;
    }

    //-- Step 1: Detect the keypoints …

我正在开发一个OpenCV 3.0.0 32位分段项目,并从OpenCV 复制+粘贴一些示例代码.不幸的是,当我构建它时,包含所有依赖项和库,它会给我以下错误:

1>Source.cpp
