OpenCV：無法從contrib存儲庫中找到模塊（跟蹤器，selectROI）

我正在研究涉及跟蹤對象的項目，並試圖讓OpenCV contrib repo的TrackerKCF工作。這是示例代碼，我在網上得到：OpenCV：無法從contrib存儲庫中找到模塊（跟蹤器，selectROI）

#include <opencv2/core/utility.hpp> 
#include <opencv2/video/tracking.hpp> 
#include <opencv2/videoio.hpp> 
#include <opencv2/highgui.hpp> 
#include <iostream> 
#include <cstring> 

using namespace std; 
using namespace cv; 

int main(int argc, char** argv){ 
    // show help 
    if(argc<2){ 
    cout<< 
     " Usage: example_tracking_kcf <video_name>\n" 
     " examples:\n" 
     " example_tracking_kcf Bolt/img/%04.jpg\n" 
     " example_tracking_kcf faceocc2.webm\n" 
     << endl; 
    return 0; 
    } 

    // create the tracker 
    Ptr<Tracker> tracker = TrackerKCF::create(); 

    // set input video 
    std::string video = argv[1]; 
    VideoCapture cap(video); 

    Mat frame; 

    // get bounding box 
    cap >> frame; 
    Rect2d roi= selectROI("tracker", frame, true, false); 

    //quit if ROI was not selected 
    if(roi.width==0 || roi.height==0) 
    return 0; 

    // initialize the tracker 
    tracker->init(frame,roi); 

    // do the tracking 
    printf("Start the tracking process, press ESC to quit.\n"); 
    for (;;){ 
    // get frame from the video 
    cap >> frame; 

    // stop the program if no more images 
    if(frame.rows==0 || frame.cols==0) 
     break; 

    // update the tracking result 
    bool isfound = tracker->update(frame,roi); 
    if(!isfound) 
    { 
     cout << "The target has been lost...\n"; 
     waitKey(0); 
     return 0; 
    } 

    // draw the tracked object 
    rectangle(frame, roi, Scalar(255, 0, 0), 2, 1); 

    // show image with the tracked object 
    imshow("tracker",frame); 

    //quit on ESC button 
    if(waitKey(1)==27)break; 
    } 
}

但是，我得到了以下錯誤：

tracktest.cpp: In function ‘int main(int, char**)’: 
tracktest.cpp:33:7: error: ‘Tracker’ was not declared in this scope 
    Ptr<Tracker> tracker = TrackerKCF::create(); 
    ^

    Ptr<Tracker> tracker = TrackerKCF::create(); 
      ^

    Ptr<Tracker> tracker = TrackerKCF::create(); 
         ^

    Rect2d roi= selectROI("tracker", frame, true, false); 
                ^

    tracker->init(frame,roi); 
     ^

    bool isfound = tracker->update(frame,roi); 
         ^
./tracktest.sh: line 5: ./tracktest: No such file or directory

我試圖重新安裝OpenCV的3.1.0和相應的contrib回購，這似乎make完成得很好。我還試圖找到tracker.cpp在我的OpenCV源目錄中，但沒有彈出。

我認爲這是因爲我錯誤地安裝了contrib模塊，但我不確定。任何人都可以弄清楚什麼是錯的？提前致謝。

我想跟蹤頭文件是''。包括這個文件，看看它是否有效。 – sgarizvi

沒有'tracking.hpp' :( 'tracktest.cpp：16：32：致命錯誤：opencv2/tracking.hpp：沒有這樣的文件或目錄編譯已終止 ./tracktest.sh：第5行：./ tracktest：沒有這樣的文件或目錄 ' – zeklewa

也我認爲這已經包含在'#include ' – zeklewa

由於我莫名的愚蠢，我忘了跑make install。現在都很好！

我仍然收到錯誤：：錯誤：'selectROI'未在此範圍內聲明 –

有沒有辦法可以檢查我是否安裝了opencv_contrib？ –
