你的代码看起来已经实现了使用Open3D库将STL格式文件转换为PCD格式文件的功能,只是需要一些修改来确保它可以正常工作。下面是修改后的代码:
```python
import os
import open3d as o3d
path = "D:/data/Dynamo_Code/Revit_Model/Revit_Model/" # 待读取的文件夹
path_list = os.listdir(path)
outpath = "C:/Users/Hupan/Desktop/revit_model/revit_model/"
for filename in path_list:
importpath_name = os.path.join(path, filename)
mesh = o3d.io.read_triangle_mesh(importpath_name)
point_cloud = mesh.sample_points_uniformly(number_of_points=1000)
file_name, file_extension = os.path.splitext(filename)
outpath_name = os.path.join(outpath, file_name + ".pcd")
o3d.io.write_point_cloud(outpath_name, point_cloud)
```
主要修改如下:
1. 将导入路径和导出路径的定义放在循环外部,避免每次循环都重新定义路径。
2. 使用 `os.path.splitext()` 函数来获取文件名和文件扩展名,以便在导出时将扩展名更改为 `.pcd`。
3. 修改导出路径的拼接方式,将新的文件名与导出路径合并。
请确保你已经正确安装了Open3D库,并且将路径替换为你自己的文件夹路径。这样,代码就能够按照你的需求将STL文件转换为PCD文件。
