cvConvexityDefects在OpenCV 2.X / C ++？ [英] cvConvexityDefects in OpenCV 2.X / C++?

问题描述

我使用OpenCV 2.2，我需要确定凸包的凸性缺陷。我在文档中找不到任何关于凸面缺陷的内容，这让我很奇怪如果它仍然支持在OpenCV 2.X或者如果它被重命名？

I'm using OpenCV 2.2 and I need to determine convexity defects of a convex hull. I can't find anything on convexity defects in the documentation which makes me wonder if it is still supported in OpenCV 2.X or if it was renamed?

无论如何，我尝试使用C函数

Anyways, I tried using the C function

CvSeq* cvConvexityDefects(const CvArr* contour, const CvArr* convexhull, CvMemStorage* storage=NULL )

但是，我不能转换我的 std :: vector< Point> hull 转换为 CvArr 。 CvArr 参数到 cvConvexityDefects 应该是一维和连续的int数组，我没有成功创建尝试投放，手动复制到CvSeq结构中，...）。

However, I'm not able to convert my std::vector<Point> hull into CvArr. The CvArr parameters to cvConvexityDefects should be 1-dimensional and continuous array of int's, which I had no success in creating (tried casting, manual copying into a CvSeq structure, ...).

任何想法？
