pip3 install open3d-python
Open3D是一个开放源代码库,支持快速开发处理3D数据的软件。
先画一堆云
import open3d as o3d #导入open3d库 import numpy as np #导入numpy points = np.random.rand(10000, 3) point_cloud = o3d.PointCloud() point_cloud.points = o3d.Vector3dVector(points) o3d.draw_geometries([point_cloud])
再读取一只兔子
import open3d as o3d import numpy as np #读点云数据 pcd = o3d.io.read_point_cloud(r"D:\pythonAds2021\open3d\bunny10k.ply") print(pcd) o3d.visualization.draw_geometries([pcd],width=800,height=600)
可任意把玩。
import open3d as o3d # import open3d_tutorial as o3dtut import numpy as np print("Open3D read Point Cloud") pcd = o3d.io.read_triangle_mesh("thu_statue.ply") #newrabbit.pcd") print(pcd) pcd.compute_vertex_normals() pcdmesh = pcd.sample_points_poisson_disk(3000) o3d.visualization.draw_geometries([pcdmesh],point_show_normal=True) radii=[0.005, 0.01, 0.02, 0.04] ballmesh = o3d.geometry.TriangleMesh.create_from_point_cloud_ball_pivoting(pcdmesh,o3d.utility.DoubleVector(radii)) print(ballmesh) o3d.visualization.draw_geometries([ballmesh]) o3d.visualization.draw_geometries([pcd, ballmesh])
还能再画个球。
