opencv函数制作的秒针模型

曾经做过，没想到这次再次写这篇代码却用了这么久的时间。这回我要记住他。

#include"cv.h"
#include"highgui.h"

int main()
{
    IplImage* Plane = cvCreateImage(cvSize(500,500),8,3);
    cvAddS(Plane,cvScalar(100,0,200),Plane);
    cvCircle(Plane,cvPoint(250,250),100,cvScalar(0,180,0),2);
    cvPutText(Plane,"12",cvPoint(236,145),&cvFont(1,1),cvScalar(50,150,10));
    cvPutText(Plane, "3", cvPoint(355, 250), &cvFont(1, 1), cvScalar(50, 150, 10));
    cvPutText(Plane, "4", cvPoint(345, 300), &cvFont(1, 1), cvScalar(50, 150, 10));
    cvPutText(Plane, "5", cvPoint(315, 340), &cvFont(1, 1), cvScalar(50, 150, 10));
    cvPutText(Plane, "6", cvPoint(250, 365), &cvFont(1, 1), cvScalar(50, 150, 10));
    cvPutText(Plane, "7", cvPoint(185, 345), &cvFont(1, 1), cvScalar(50, 150, 10));
    cvPutText(Plane, "8", cvPoint(150, 305), &cvFont(1, 1), cvScalar(50, 150, 10));
    
    cvPutText(Plane, "9", cvPoint(135, 250), &cvFont(1, 1), cvScalar(50, 150, 10));
    cvPutText(Plane, "10", cvPoint(140, 200), &cvFont(1, 1), cvScalar(50, 150, 10));
    cvPutText(Plane, "11", cvPoint(175, 165), &cvFont(1, 1), cvScalar(50, 150, 10));
    cvPutText(Plane, "1", cvPoint(300, 160), &cvFont(1, 1), cvScalar(50, 150, 10));
    cvPutText(Plane, "2", cvPoint(340, 195), &cvFont(1, 1), cvScalar(50, 150, 10));
    cvCircle(Plane,cvPoint(250,250),3,cvScalarAll(50),4);
    IplImage* img = cvCreateImage(cvGetSize(Plane),8,3);
    double angle = 0;
    int x = 250;
    int y=150;
    int dx = 0;
    int dy = 0;

    while (true)
    {
        cvCopy(Plane,img);
        dy = 100 * cos(angle);
        dx = 100 * sin(angle);
        angle +=0.0515;
        cvLine(img,cvPoint(250,250),cvPoint(250+dx,250-dy),cvScalar(100,90,0),1);
        cvShowImage("Clock", img);
        if (cvWaitKey(1000) == 27)
        {
            if (cvWaitKey(0) == 27)continue;
        }
    }
    
    cvWaitKey(0);
    return 0;
}
int ToA(int x1,int y1, int x2,int y2,int r)
{
    return 0;
}
