create_from_point_cloud_correspondences是Open3D中open3d.geometry.LineSet类的一个函数,可以通过点云之间的对应关系创建线集合。
open3d.geometry.LineSet.create_from_point_cloud_correspondences(source: open3d.geometry.PointCloud, target: open3d.geometry.PointCloud, correspondences: np.ndarray)
source
:open3d.geometry.PointCloud类型,表示源点云。target
:open3d.geometry.PointCloud类型,表示目标点云。correspondences
:numpy数组类型,表示点之间的对应关系。返回open3d.geometry.LineSet类型的线集合。
import open3d as o3d
import numpy as np
# 创建源点云
source = o3d.geometry.PointCloud()
source.points = o3d.utility.Vector3dVector(np.random.rand(100, 3))
# 创建目标点云
target = o3d.geometry.PointCloud()
target.points = o3d.utility.Vector3dVector(np.random.rand(100, 3))
# 创建点之间的对应关系
correspondences = np.random.randint(0, 100, (50, 2))
# 创建线集合
lineset = o3d.geometry.LineSet.create_from_point_cloud_correspondences(source, target, correspondences)
# 可视化
