两个点云相加合并（附open3d python代码）

把多个点云合并的需求经常出现，直接可把它们合并起来。

# coding:utf-8
import open3d as o3d
import numpy as np

# --------------------------- 加载点云 ---------------------------
print("->正在加载点云... ")
pcd1 = o3d.io.read_point_cloud("lidar1.pcd")
pcd2 = o3d.io.read_point_cloud("lidar2.pcd")

print("原始点云pcd1：", pcd1)
print("原始点云pcd2：", pcd2)

pcd_all = pcd2 + pcd1
print("原始点云pcd_all：", pcd_all)
# ==============================================================
o3d.visualization.draw_geometries([ pcd_all], window_name="wechat 394467238 ")
