Open3D Visualization - Adding Text Labels to Point Clouds

Open3D is an open source multidimensional graphics library that provides a wealth of functions to process and visualize three-dimensional data. When using Open3D for point cloud visualization, we often need to add text labels to describe specific points or areas. This article will introduce how to use the Open3D library to add text labels to the point cloud, and give the corresponding source code.

First, we need to install the Open3D library. It can be installed through the pip command:

pip install open3d

After the installation is complete, we can import the Open3D library and load the point cloud data. Here is a simple example showing how to load a point cloud file and visualize it:

import open3d as o3d

# 加载点云文件
pcd = o3d.io.read_point_cloud("point_cloud.pcd")

# 可视化点云
o3d.visualization.draw_geometries
