algorithm - RANSAC differentiating between line and plane

Question

I am trying to extract planes from a 3D point dataset containing power cables. Now the power cables are also getting extracted as planes. So my question is it possible to use RANSAC to differentiate between a line and plane. I can perform an eigen value based analysis but I am looking for some way to perform as part of the RANSAC algorithm itself.

Answer 1

找到了一个简单的解决方案。发布它以供其他人帮助。RANSAC 首先从三个点找到一个平面。所以我们从三个点找到两个向量。我们可以检查两个向量的点积，看看它们是否接近 1。如果是，它们代表一条线。
