“BackgroundSubtractorMOG”不是“cv”的成员

‘BackgroundSubtractorMOG’ is not a member of ‘cv’

我正在使用运动检测器脚本,但是当我 运行 我的代码时,我每次使用此功能时都会收到此错误,但我不知道为什么会出错。

我正在使用 opencv3,下面是我的代码。我尝试 运行 其他示例,我从网络上获取它以实现相同的功能,但错误仍然存​​在。有什么办法解决吗?

这是错误:

cv.cpp: In function ‘int main()’:

cv.cpp:23:4: error: ‘BackgroundSubtractorMOG’ is not a member of ‘cv’

我的代码:

#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <vector>
#include <iostream>
#include <sstream>
#include <opencv2/video/background_segm.hpp>  
using namespace std;


int main()
{
   //Openthevideofile
   cv::VideoCapture capture("/home/shar/Desktop/op.mp4");
   //checkifvideosuccessfullyopened
   if (!capture.isOpened())
     return 0;
   //currentvideoframe
   cv::Mat frame;
   //foregroundbinaryimage
   cv::Mat foreground;
   cv::namedWindow("ExtractedForeground");
   //TheMixtureofGaussianobject
   //used with all default parameters
   cv::BackgroundSubtractorMOG mog;

   bool stop(false);
   //forallframesinvideo
   while(!stop){
  //readnextframeifany
    if(!capture.read(frame))
      break;
   //updatethebackground
   //andreturntheforeground
    mog(frame,foreground,0.01)
  //learningrate
  //Complementtheimage
    cv::threshold(foreground,foreground,128,255,cv::THRESH_BINARY_INV);
  //showforeground
    cv::imshow("ExtractedForeground",foreground);
  //introduceadelay
  //orpresskeytostop
    if(cv::waitKey(10)>=0)
    stop=true;
  }


}

正如@shar所说,答案就在中。为了创建指向算法的智能指针,您需要执行以下操作:

  cv::Ptr<cv::BackgroundSubtractorMOG2> pMOG2 = cv::createBackgroundSubtractorMOG2();

编辑:

并使用算法:

 float learningRate = 0.01; // or whatever
 cv::Mat foreground; 
 pMOG2->apply(frame, foreground, learningRate);
