[英]Drawing circles at BENDING points of convex hull
I am trying to figure out of drawing circles at the BENDING points of a convex hull. 我试图找出凸包的弯曲点处的绘制圆。 Using the sample from OpenCV documentation for convex hull , I have a convex hull. 使用OpenCV文档中的凸包示例,我有一个凸包。 But I am not really sure on how to draw the circles at the points where the finger tips are which basically are the bending points for the convex hull. 但是我不确定如何在指尖所在的点上绘制圆,这些点基本上是凸包的弯曲点。
I hope someone can guide me through this. 我希望有人可以指导我。
Thanks for the help 谢谢您的帮助
Your convex hull contains points of finger tips. 您的凸包包含指尖。 You can find those points by approximating with a simpler shape. 您可以通过使用更简单的形状进行近似来找到这些点。 You can do that with cv::approxPolyDP . 您可以使用cv :: approxPolyDP做到这一点 。 After that, draw circle on the points with cvCircle, or cv::Circle . 之后,使用cvCircle或cv :: Circle在点上画圆 。
