Cylindrical neighborhood search for Open3D point clouds

First, the algorithm principle

  The implementation process in the code is very clear and needs no introduction.

Second, the code implementation

import open3d as o3d
import numpy as np


# ---------------------------------------读取点云--------------------------------------
pcd = o3d.io.read_point_cloud("data//投影点测试.pcd")
# 如果点云不包含颜色信息，则将点云渲染成灰色
