opencv 从任意区域提取路径(中心线) [英] opencv extract path (centerline) from arbitrary area
问题描述
我有一个任意区域，想提取一条路径(一系列像素).路径应该开始和结束，以便您走最长的路，但始终保持在边界之间的中心.
I have an arbitray area and want to extract a path (series of pixels). The path should start and end so that you walk the longest way but always stay in the center, between your borders.
有什么明智的方法可以在 opencv 中实现这一点吗?基本上像侵蚀这样的形态过滤器(找到边界之间的中间)听起来不错.但是我不想缩短路径的长度.
Is there any sensible way to implement this in opencv? Basically a morphologic filter like erosion (to find the middle between the borders) sounds good. However I do not want to shorten the the length of the path.
它不需要是一个全自动的解决方案.用户输入，例如标记路径的起点和终点也是一种选择.
It does not need to be a fully automatic solution. User input, e.g. marking the start and end point of an path, is also an option.
这是一个用油漆绘制的(相当糟糕的)示例.我想你明白了.
Here is a (rather poor) example drawn with paint. I guess you get the point.

我认为您是在要求骨架化.请检查以下链接.
I think you are asking for skeletonization. Check the following links please.
