opencv中,convexhull()能够得到一系列点的凸包,比如由点组成的轮廓,通过ConvexHull函数,得到凸包。 可以用来做手势的识别。 几何图形 我们用以下的Python代码来自己绘制一张简单的多边形的图片 importcv2importnumpyasnp# 新建512*512的空白图片img = np.zeros((512,512,3), np.uint8)# 平面点集pts = np.array...
python ConvexHull 转成polygon Python中的凸包(ConvexHull)与多边形(Polygon)转换 在计算机科学和数学中,凸包是一个重要的概念,它描述了一个点集的最小凸多边形或多面体。在二维空间中,凸包是一个凸多边形,其所有顶点都来自于原始点集,并且包含了原始点集中的所有点。在Python中,我们可以使用scipy库中的ConvexHull类...

In this post, we will learn how to find the Convex Hull of a shape (a group of points). We will briefly explain the algorithm and then follow up with C++ and Python code implementation using OpenCV. What is a Convex Hull? Let us break the term down into its two parts — Convex and...
