在Ubuntu中使用OpenCV进行编译警告

Compile warning using Opencv in ubuntu

本文关键字：编译 警告 OpenCV Ubuntu      更新时间：2023-10-16

亲爱的社区，我一直在研究一些openCV，我发现了有趣的吸引人跟踪内容，所以我找到了一个入门的源代码，但是当我尝试编译它时我得到了此警告：

ojos2.cpp：15：5：警告：" int main（int*，char **）"的第一个论点应为" int" [-wmain]

更清楚地清楚我是从Ubuntu终端编译的，这是代码

#include "cv.h"
#include"highgui.h"
IplImage* GetThresholdedImage(IplImage* img)
{
IplImage *imgHSV=cvCreateImage(cvGetSize(img),8,3);
cvCvtColor(img,imgHSV,CV_BGR2HSV);
IplImage *imgThresh=cvCreateImage(cvGetSize(img),8,1);
cvInRangeS(imgHSV,cvScalar(0, 84, 0, 0),cvScalar(179, 256, 11, 0),imgThresh);
cvReleaseImage(&imgHSV);
return imgThresh;
}
int main(int *argv,char **argc)
{
IplImage *imgScribble= NULL;
char c=0;
CvCapture *capture;
capture=cvCreateFileCapture("main.avi");
if(!capture)
{
    printf("Camera could not be initialized");
    exit(0);
}
cvNamedWindow("Simple");
cvNamedWindow("Thresholded");
while(c!=32)
{
    IplImage *img=0;
    img=cvQueryFrame(capture);
    if(!img)
        break;
    if(imgScribble==NULL)
        imgScribble=cvCreateImage(cvGetSize(img),8,3);
    IplImage *timg=GetThresholdedImage(img);
    CvMoments *moments=(CvMoments*)malloc(sizeof(CvMoments));
    cvMoments(timg,moments,1);
    double moment10 = cvGetSpatialMoment(moments, 1, 0);
    double moment01 = cvGetSpatialMoment(moments, 0, 1);
    double area = cvGetCentralMoment(moments, 0, 0);
    static int posX = 0;
    static int posY = 0;
    int lastX = posX;
    int lastY = posY;
    posX = moment10/area;
    posY = moment01/area;
     // Print it out for debugging purposes
    printf("position (%d,%d)n", posX, posY);
    // We want to draw a line only if its a valid position
    if(lastX>0 && lastY>0 && posX>0 && posY>0)
    {
        // Draw a yellow line from the previous point to the current point
        cvLine(imgScribble, cvPoint(posX, posY), cvPoint(lastX, lastY), cvScalar(0,255,255), 5);
    }
    // Add the scribbling image and the frame...
    cvAdd(img, imgScribble, img);
    cvShowImage("Simple",img);
    cvShowImage("Thresholded",timg);
    c=cvWaitKey(3);
    cvReleaseImage(&timg);
    delete moments;
}
//cvReleaseImage(&img);
cvDestroyWindow("Simple");
cvDestroyWindow("Thresholded");
}

任何帮助都会有用

预先感谢

原型应该是 int main (int argv, char *argc[])，主要是错误的是argv的指针-char **argc和char *argc[]是两种说话的方法指向字符数组的指针，而不是作为指针指向指针。

int main（int argv，char ** argc）警告消失了。
