本文详细解析了一个在使用OpenCV进行图像处理时遇到的错误问题，并提供了有效的解决方案。通过改变变量名，成功解决了错误，使得代码能够正常运行。

当运行以下代码时，

CvPoint rad1,rad2,rad3,rad4; //four circle center points
rad1=cvPoint(80,160),rad2=cvPoint(151,89),rad3=cvPoint(222,160),rad4=cvPoint(151,231);
cvCircle(mi,rad1,50,fcol,CV_FILLED,CV_AA,0); //paint the four circles
cvCircle(mi,rad2,50,fcol,CV_FILLED,CV_AA,0);
cvCircle(mi,rad3,50,fcol,CV_FILLED,CV_AA,0);
cvCircle(mi,rad4,50,fcol,CV_FILLED,CV_AA,0);

出现错误如下：
