PCL Euclidean Distance Clustering Source Code Analysis

I spent some time looking at the relevant algorithms and took a simple note.

The specific implementation method of the Euclidean algorithm is roughly as follows:

Determine if a point is inside a polygon (C++ code)

I tested the code and made a few small changes to improve the efficiency.

Determine whether it is inside the polygon based on the number of intersection points between points and the edges of the polygon
