STL 到点云
STL to pointcloud
我正在尝试使用 open3d 库将 stl 文件转换为点。
mesh = o3d.io.read_triangle_mesh("./stl.stl")
pcd = o3d.geometry.PointCloud()
pcd.points = mesh.vertices
pcd.colors = mesh.vertex_colors
pcd.normals = mesh.vertex_normals
问题是需要加载 mesh.surfaces 而不是顶点,但我看不到 open3d.open3d.geometry.TriangleMesh.Surface 对象。我需要对齐曲面而不是顶点。
如何从三角网格中获取点?
Input
Output
这可能有帮助:
open3d.geometry.sample_points_uniformly(input, number_of_points=100)
Function to uniformly sample points from the mesh.
Parameters
input (open3d.geometry.TriangleMesh) – The input triangle mesh.
number_of_points (int, optional, default=100) – Number of points that should be uniformly sampled.
Returns
open3d.geometry.PointCloud
