C++ 当对象靠近opencv时将帧保存到文件

C++ 当对象靠近opencv时将帧保存到文件,c++,file,opencv,save,frame,C++,File,Opencv,Save,Frame,我正在跟踪两个对象,当它们彼此的距离在100以内时,我希望保存一帧。 Im使用以下工具测量距离: bool bSavePic = false; void example{ int x1,y1,x2,y2; int distance; //distance between two objects if(initialMarkers.size()>1){ x1 = initialMarkers.at(0).getXPos(); y1 = initialMarkers.at(0).g

我正在跟踪两个对象,当它们彼此的距离在100以内时,我希望保存一帧。 Im使用以下工具测量距离:

bool bSavePic = false;

void example{
    int x1,y1,x2,y2;
int distance; //distance between two objects

if(initialMarkers.size()>1){
x1 = initialMarkers.at(0).getXPos();
y1 = initialMarkers.at(0).getYPos();
x2 = initialMarkers.at(1).getXPos();
y2 = initialMarkers.at(1).getYPos();

distance = (int)sqrt((double)((x2-x1)*(x2-x1) + (y2-y1)*(y2-y1)));

cv::putText(cameraFeed,intToString(distance),cv::Point(50,50),1,1,Scalar(255,0,0));

  if (distance < 100 )
        {
            bSavePic= true;
            }else{
            bSavePic= false;
        }
     }
boolbsavepic=false;
无效示例{
int-x1,y1,x2,y2;
int distance;//两个对象之间的距离
如果(initialMarkers.size()>1){
x1=initialMarkers.at(0).getXPos();
y1=initialMarkers.at(0).getYPos();
x2=initialMarkers.at(1).getXPos();
y2=initialMarkers.at(1).getYPos();
距离=(int)sqrt((双)((x2-x1)*(x2-x1)+(y2-y1)*(y2-y1));
cv::putText(cameraFeed,intToString(距离),cv::Point(50,50),1,1,Scalar(255,0,0));
如果(距离<100)
{
bsavpic=真;
}否则{
b视觉=假;
}
}
我遇到的问题是,当它们彼此的距离在100以内时,下面的代码输出视频流,然后在标记距离再次大于100时保存帧

if (bSavePic == true)
        {
            putText(cameraFeed,"Saving Image",Point(50,70),1,1,Scalar(0,0,255),1);
            waitKey(10);
            capture >> saveImage;
        }

    char buffer[1000];
    for(int c=0; c<1; c++)
        {
            sprintf(buffer,"C:\\Users\\Scott\\Documents\\Visual Studio 2010\\Projects\\MultipleObjectTracking\\Image-%d.jpg",c);
            imwrite(buffer, saveImage);             
        }

    if(!saveImage.empty())
        {
            Mat readImage;
            readImage = imread(buffer,CV_LOAD_IMAGE_COLOR);
            imshow(windowName4, readImage);
        }
if(bsavpic==true)
{
putText(cameraFeed,“保存图像”,点(50,70),1,1,标量(0,0255),1);
等候室(10);
捕获>>保存图像;
}
字符缓冲区[1000];
对于(int c=0;c我用

bool bSingleFrame = true;

 int main{

        if (bSavePic == true)//distance<100
    {

        if (bSingleFrame == true)
        {
        putText(cameraFeed,"Saving Image",Point(50,70),1,1,Scalar(0,0,255),1);
        Mat saveImage;
        capture >> saveImage;
            stringstream ssFileName;                    //string stream initialised through each passing of while loop
            ssFileName << "Image-" << c << ".jpg";      //File name based on frame captured 0++
            ssFileName >> sFileName;


        if(!saveImage.empty())                          //check if frame captured is stored in matrix
        {
            cout << "Frame captured." << endl;          //if data in frame cout
            imwrite(sFileName.c_str(), saveImage);      //save frame
            saveImage.release();                        
            c++;
            if (bSavePic == true)                       //if distance still <100
            {
                bSingleFrame = false;
            }

            Mat readImage;
            readImage = imread(sFileName.c_str(),CV_LOAD_IMAGE_COLOR);  
            imshow(windowName4, readImage);             //show captured frame in new window
        }else{
            cout << "Error, could not capture frame to save." << endl;
        }//if(!saveImage.empty())
        }//bSingleFrame
    }//ifbSavePic

    if (bSavePic == false)
            {
                bSingleFrame = true;//if distance back >100 can capture another frame
                }
}
boolbsingleframe=true;
int main{
如果(bSavePic==true)//距离>保存图像;
stringstream ssFileName;//通过每次传递while循环初始化的字符串流
ssFileName
