opencv在灰度图上,绘制polylines
opencv在灰度图上,绘制多边形
1、这是在彩色图上进行绘制:
somaBackground = np.zeros((self.imgsize[1], self.imgsize[0], 3), dtype=int) somaBackground = cv.polylines(somaBackground, line, 2, (0, 255, 250), 2)
2、这是在灰度图上进行绘制(没有搞定)
技巧 | OpenCV中如何绘制与填充多边形_小白学视觉的博客-CSDN博客
somaBackground = np.zeros((width, heigh), dtype=np.uint16)
somaBackground = cv.polylines(somaBackground, line, 2, 255, 2)
这个效果不好
下边的方法仅供参考:
3、使用fillPoly
somaBackground = np.ones((width, heigh, 3)) * (255, 255, 255)
somaBackground = cv.fillPoly(somaBackground, line, (0, 255, 250))
