写出python代码实现:1.使用open3d读取点云数据。2.根据高程提取出输电线路点云数据并将其渲染为蓝色进行可视化,并保存为pcd文件,命名为line 3.未提取的点云渲染为绿色进行可视化,并保存为pcd文件,命名为other

以下是 Python 代码实现:
import open3d as o3d
# 读取点云数据
pcd = o3d.io.read_point_cloud("point_cloud_data.pcd")
# 根据高程提取输电线路点云数据
line_points = []
other_points = []
for point in pcd.points:
if point[2] > 10: # 假设高程大于10为输电线路点云数据
line_points.append(point)
else:
other_points.append(point)
# 将输电线路点云数据渲染为蓝色
line_pcd = o3d.geometry.PointCloud()
line_pcd.points = o3d.utility.Vector3dVector(line_points)
line_pcd.paint_uniform_color([0, 0, 1]) # 蓝色
o3d.io.write_point_cloud("line.pcd", line_pcd)
# 将未提取的点云渲染为绿色
other_pcd = o3d.geometry.PointCloud()
other_pcd.points = o3d.utility.Vector3dVector(other_points)
other_pcd.paint_uniform_color([0, 1, 0]) # 绿色
o3d.io.write_point_cloud("other.pcd", other_pcd)
# 可视化
o3d.visualization.draw_geometries([line_pcd, other_pcd])
