Open3D realizes point cloud projection to specified plane
In recent years, point cloud technology has been widely used in computer vision and 3D reconstruction. Open3D is an open source computer vision library that provides a powerful set of functions to process and analyze point cloud data. One of the common requirements is to project the point cloud onto a specified plane for visualization or subsequent processing. This article will introduce how to use Open3D to realize the function of point cloud projection to a specified plane, and provide the corresponding source code.
First, we need to make sure that the Open3D library has been installed and import related modules:
import open3d as o3d
import numpy as np
Next, we need to load the point cloud data. Assuming we already have a point cloud data file, we can load it into memory with the following code:
pcd = o3d.io.read_point_cloud("point_cloud.ply")
Then, we need to define a plane on which to project the point cloud. A plane can be determined by a normal vector and an origin. we can usePlane</
