ubuntu - cvBlob示例不起作用cvLabel

我尝试在下的opencv中使用cvBlob lib进行blob检测，而Ubuntu 却在开始时就被阻止了。当我尝试在那里编译示例表单时:

#include <cv.h>
#include <highgui.h>
#include <stdio.h>
#include "cvblob.h"

using namespace cvb;
using namespace std;

int main( int argc,char** argv){
    if( argv[1] == NULL ){
        printf("\n Please Provide a valid Argument \n");
        return(0);
    }
    else{
        IplImage* src = cvLoadImage(argv[1],CV_LOAD_IMAGE_UNCHANGED);
        cvNamedWindow("Original",CV_WINDOW_AUTOSIZE);
        cvShowImage("Original",src);
    IplImage src_g;
    cvThreshold(src, src_g,35,255, CV_THRESH_BINARY);
    IplImage *labelImg=cvCreateImage(cvGetSize(src_g), IPL_DEPTH_LABEL, 1);
    CvBlobs blobs;
    unsigned int result=cvb::CvLabel(src_g, labelImg, blobs);
    cvRenderBlobs(labelImg, blobs, src, src);
    for (CvBlobs::const_iterator it=blobs.begin(); it!=blobs.end(); ++it)
    {
      cout << "Blob #" << it->second->label << ": Area=" << it->second->area << ", Centroid=(" << it->second->centroid.x << ", " << it->second->centroid.y << ")" << endl;
    }
    cvNamedWindow( "Mod", CV_WINDOW_AUTOSIZE );
    cvShowImage( "Mod", src );
    cvWaitKey(0);
        cvReleaseImage(&src);
        cvReleaseImage(&src_g);
        cvDestroyWindow("Image");
        return(0);
    }

}

我收到此错误的原始unsigned int result=cvb::CvLabel(src_g, labelImg, blobs);:

home/rrg/OpenCV-2.4.3/release/bagDetect/main.cpp: In function ‘int main(int, char**)’:
/home/rrg/OpenCV-2.4.3/release/bagDetect/main.cpp:28: error: functional cast expression list treated as compound expression
/home/rrg/OpenCV-2.4.3/release/bagDetect/main.cpp:28: error: invalid cast from type ‘cvb::CvBlobs’ to type ‘cvb::CvLabel’
make[2]: *** [CMakeFiles/bag.dir/main.o] Error 1
make[1]: *** [CMakeFiles/bag.dir/all] Error 2
make: *** [all] Error 2

我不知道应该是什么问题!

在第一个答案中提到的更改后，我得到了链接器错误:(

Linking CXX executable bag
CMakeFiles/bag.dir/main.o: In function `main':
main.cpp:(.text+0x103): undefined reference to `cvLabel'
main.cpp:(.text+0x134): undefined reference to `cvRenderBlobs'
collect2: ld returned 1 exit status

我应该在什么地方识别上述功能？(CMakeList或Makefile)？

最佳答案

您的代码中有两种错别字，它们会产生以下错误:
- IplImage src_g; ->应该声明为指针
-unsigned int result = cvb:: CvLabel (src_g，labelImg，blob)； ->使用cvLabel()代替CvLabel()

希望这可以帮助，
