PCA based geometric feature calculation of PCL point cloud processing (52)
2022-04-23 20:10:00 【Point cloud apprentice】
PCL Point cloud processing is based on PCA Calculation of geometric characteristics of （ Fifty-two ）
One 、 What is the geometry ？
Discrete point cloud , For a particular object , The point cloud on its surface has a specific geometry , For example, the pavement point is a plane , The trunk is rod-shaped , The canopy is spherical , This is very helpful for point cloud classification .
The local point cloud is based on PCA Calculate eigenvalues , Compare according to the combination of eigenvalues , To determine the distribution shape of the point cloud
Two 、 Use steps
1. Code
