Python-显示3D点云

问题描述

我有一个.PLY文件，其中包含3D点云:我想绘制它并用Python对其进行可视化..PLY文件仅包含顶点，而不包含面.

I have a .PLY file that contains a 3D Point Cloud: I want to plot it and visualize it in Python.The .PLY file contains ONLY vertex and NOT faces.

您能告诉我一个简单的Python库，该库将负责绘制3D点云吗?

重要的一点是，我对绘制网格不感兴趣，而对点云不感兴趣.

It is important to remark that I am not interested in plotting a Mesh, but just the Point Cloud.

推荐答案

对于任何想以简便方法来读取和显示Python中的PLY点云的人，我回答了我提出自己的问题，报告我发现哪种方法是我的最佳解决方案.

For anybody wondering for an easy way to read and display PLY point clouds in Python I answer my own question reporting what I've found to be the best solution in my case.

打开cmd并输入:

pip install open3d

这将在您的计算机上安装Open3D，然后您只需执行以下示例脚本即可读取和分配PLY点云:

This will install Open3D on your machine and you will then be able to read and dispaly your PLY point clouds just by executing the following sample script:

import numpy as np
from open3d import *

def main():
    cloud = read_point_cloud("cloud.ply") # Read the point cloud
    draw_geometries([cloud]) # Visualize the point cloud

if __name__ == "__main__":
    main()
