Open3D point cloud visualization and coordinate viewing
A point cloud is a set of discrete points in a three-dimensional space, which is often used to represent information such as the shape and surface texture of a three-dimensional object. Open3D is an open source library that provides rich functionality for point cloud processing and visualization. This article will introduce how to use the Open3D library to view the coordinates of the point cloud, along with the corresponding source code.
First, we need to install the Open3D library. It can be installed via the pip command:
pip install open3d
After the installation is complete, we import the Open3D library in the Python script:
import open3d as o3d
Next, we create a simple point cloud data. Here we use the creation function provided by Open3D to generate a sphere point cloud data and save it to a file:
sphere = o3d.geometry.TriangleMesh.create_sphere(radius=1.0)
sphere.
