2. DrawFilledCircle()函数的写法 DrawFilledCircle()调用了OpenCV中的circle函数,将圆画到图像img上。 void DrawFilledCircle( Mat img, Point center ) { int thickness = -1; int lineType = 8; circle( img, center,//圆心由点center定义 WINDOW_WIDTH/32,//圆的半径 Scalar( 0, 0, 255 ),//圆...
void DrawFilledCircle(Mat img, Point center) { int thickness = -1; // 线粗-1,代表实心 int lineType = 8; // 线性,8 代表联通线性 circle(img, center, WINDOW_WIDTH / 32, Scalar(0, 0, 255), thickness, lineType); } /*凹多边形绘制*/ void DrawPolygon(Mat img) { int lineType = ...

void DrawFilledCircle(Mat img, Point center){int thickness = -1;int lineType = 8;circle(img,center,WINDOW_WIDTH / 32,Scalar(0, 0, 255),thickness,lineType);} 3、DrawPolygon()函数的写法(凹边形) 说明:函数DrawPolygon调用了opencv中的fillPoly函数,用于将多边形画到图形img上,多边形的顶点集为pp...
voidcircle(Mat& img, Point center,int radius,const Scalar& color,int thickness=1,int lineType=8,int shift=0); center: 圆心坐标。 radius: 半径。 其余同上。 //绘制实心圆voidDrawFilledCircle(Mat img, Point center, int radius){intthickness = -1;//线粗intlineType =8; ...
函数DrawFilledCircle()调用了 OpenCV 中的 circle 函数,将圆画到图像 img 上,圆心由点 center 定义,圆的半径为 WINDOW_WIDTH/32,圆的颜色为Scalar(0,0,255),按BGR的格式为红色,线粗定义为 thickness = -1,因此绘制的圆是实心的。 凹多边形的绘制 ...
