OpenCV-highgui.hpp中的错误 [英] OpenCV - Error in highgui.hpp

问题描述

我正在尝试使用网络摄像头检测车道.我可以在一开始对其进行编译并对其进行测试，但是在更换了我以前使用过的机器之后. 它不再工作了.给我一些错误.

i am trying to detect lane using a web cam. i could compile it in the beginning and test it but after changing the machine which i used to work on. it isnt working any more. Gives me some error back.

以下是代码

int run() {

    bool pause = false`;`
    VideoCapture cam(0);
    //VideoCapture cam("clip.mp4");
    if(!cam.isOpened())
    {
        cout<<"\n Error Opening Device"<<endl;
        return 0;
    }
    width=cam.get(CV_CAP_PROP_FRAME_WIDTH);
    height=cam.get(CV_CAP_PROP_FRAME_HEIGHT);
    init();
    while(1)
    {
        cam >> frame;
        frameclone=frame.clone();
        drawElement(frame);
        imshow("Live Feed",frame);
        cvtColor(frameclone,bw,CV_RGB2GRAY);
        blur( bw, bw, Size(5,5) );
        Canny( bw, canny,0,75,3);
        imshow("canny",canny);
        regionofinterest();
        cvtColor(canny,canny,CV_GRAY2BGR);
        imshow("debug",canny);
        //houghT();
        imshow("ROI",frame);
        switch(waitKey(18))
        {
            case 113:
                cout<<"Exiting"<<endl;
                return -1;
                break;
            case 033:
                cout<<"Exiting"<<endl;
                return -1;
                break;
            case 112:
                pause=!pause;
                cout<<"Code Paused"<<endl;
                if(pause==true)
                {
                    switch(waitKey())
                        case 112:
                            pause=!pause;
                            cout<<"Code Resumed"<<endl;
                            break;
                }
        }
    }
}

我也包含了

#include "opencv2/opencv.hpp"
#include "opencv2/photo/photo.hpp"
#include "opencv2/imgproc/imgproc.hpp"
#include "opencv2/highgui.hpp"
#include "iostream"
#include "stdio.h"

但是它仍然给我以下错误:-

But still it gives me the following error:-

我使用了cmake和opencv 3.0.0 alpha

i used cmake and opencv 3.0.0 alpha

推荐答案

我遇到了同样的问题.尝试包括

I encountered the same problem. Try including

#include <highgui.h>
