3. DrawPolygon()函数的写法 DrawPolygon()调用了OpenCV的fillPoly函数,将多边形画到图像img上。 void DrawPolygon( Mat img ) { int lineType = 8; //创建一些点 Point rookPoints[1][20]; rookPoints[0][0] = Point( WINDOW_WIDTH/4, 7*WINDOW_WIDTH/8 ); rookPoints[0][1] = Point( 3*WINDOW...

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ppt,要绘制的多边形顶点数目为npt,绘制的多边形数量为1,多边形的颜色定义为白色(255,255,255)。 /*实现凹边形的绘制*/void DrawPolygon(Mat img){int lineType = 8;//创建一些点Point rookPoints[1][20];rookPoin...
DrawEllipse(atomImage, 90); DrawEllipse(atomImage, 45); DrawEllipse(atomImage, -45); // 绘制圆心 DrawFilledCircle(atomImage, Point(WINDOW_WIDTH / 2, WINDOW_WIDTH / 2)); // 绘制多边形 DrawPolygon(rookImage); // 绘制矩形 rectangle(rookImage, Point(0, 7 * WINDOW_WIDTH / 8), Point(...
方法/步骤 1 绘制的多边形如下图所示。2 调用的库如下。3 主函数如下，首先生成一张三通道的黑色画布，再调用DrawPolygon函数在定义的Mat上添加多边形。4 多边形函数如下，主要介绍下官方提供的cv：：fillPloy函数。cv：：fillPloy（Mat img，const cv::Point* ppt,const int* npt,int ncounters,Scalar（，，）...
