VS2010 OpenCV配置

其实很简单，不过有个小问题需要注意一下，折腾了很长时间。

 

下载后解压到某个目录下(XX)，在visual studio的新建工程里，右键属性，加三个东西即可

c++,general, Additional include directory, XX\opencv\build\include\opencv;XX\opencv\build\include\opencv2;D:\Library\opencv\build\include

link,general, Additional Library directory, XX\opencv\build\include\opencv;XX\opencv\build\include\opencv2;D:\Library\opencv\build\include

      input,   Addtional Dependencies ,

opencv_calib3d231d.lib
opencv_contrib231d.lib
opencv_core231d.lib
opencv_features2d231d.lib
opencv_flann231d.lib
opencv_gpu231d.lib
opencv_haartraining_engined.lib
opencv_highgui231d.lib
opencv_imgproc231d.lib
opencv_legacy231d.lib
opencv_ml231d.lib
opencv_objdetect231d.lib
opencv_ts231d.lib
opencv_video231d.lib

 然后把 XX\opencv\build\x86\vc10\bin 加到环境变量里边就OK了

 

注意如果是Debug模式下，lib里边只能加上边这些带d的lib（debug),Release下，相应改成对应的lib（没有d)，

如果在Debug模式下，把lib目录下所有的lib文件都加来，就会有问题，比如,

#include <opencv.hpp>
#include <iostream>

using namespace cv;
using namespace std;


int main()
{
    Mat img;
    img = imread("E:\\204\\testface12.jpg",CV_LOAD_IMAGE_COLOR);
    if(!  img.data){
        cout<<"Could not find image.."<<endl;
        return 0;
    }

    namedWindow("Display window",CV_WINDOW_AUTOSIZE);
    imshow("Display window",img);

    waitKey(0);
    return 0;
}

虽然E:\204\testface12.jpg 文件确实存在，不过运行后，一直是Could not find image, 不过下面C风格的读入显示就没有问题

#include <opencv.hpp>
#include <iostream>

using namespace cv;
using namespace std;

int main()
{
    
    IplImage* img=cvLoadImage("E:\\204\\testface12.jpg");
    cvNamedWindow("name");
    cvShowImage("name",img);
    cvWaitKey(0);
    return 0;
}

 

当然，debug模式下，不把哪些没有d的lib加进来，两段代码就都没有问题了。

 

 

补充：按理说，这样应该就可以了，不过OpenCV2.3好像有点问题，比如，下面这段代码就会报错

#include <opencv.hpp>
#include <iostream>

using namespace cv;
using namespace std;


int main()
{

    Mat img;
    img = imread("E:\\204\\testface12.jpg",CV_LOAD_IMAGE_COLOR);
    if(!  img.data){
        cout<<"Could not find image.."<<endl;
        return 0;
    }
    
    Mat grayimg;
    cvtColor(img,grayimg,CV_RGB2GRAY);

    imshow("gray image",grayimg);
    waitKey(0);
    return 0;
}

执行时，会报tbb_debug.dll missing, 去http://threadingbuildingblocks.org/ver.php?fid=182， 下载相应的压缩包，然后解压，取出tbb40_20120201oss\bin\ia32\vc10\tbb_debug.dll,搁到exe的路径下就可以了。
（之前用的是 tbb40_20120201oss\bin\intel64\vc10\tbb_debug, 一直有问题。。。看来只能用32bit的dll才行）
