Project Point Cloud to Plane
|
This operator has two versions:
The core functionality of both is identical; they only differ in the type of Pointcloud data processed. The output Convex point cloud will retain the type of the input Pointcloud. |
Function Description
This operator is used to project each point in the input Pointcloud data onto one or more user-defined geometric planes. The target projection plane can be specified by providing a plane equation or a plane normal vector.
Use Cases
-
Data Analysis: Projecting a 3D Pointcloud to a 2D plane can simplify analysis, such as observing the distribution of points on a specific cross-section, or preparing for subsequent 2D image processing algorithms.
-
Feature Extraction: Projecting a Pointcloud to a specific plane before shape recognition or feature description may help highlight certain geometric features.
-
Localization and Alignment: Projecting a Pointcloud onto a known plane (such as the ground or a tabletop) can assist in determining the object’s position or performing pose alignment.
Inputs and Outputs
Input Items |
Pointcloud: The input Pointcloud or Point Cloud List. Projection axis: A list containing projection axis/plane information corresponding one-to-one with the input Point Cloud List. |
Output Items |
Projection point cloud: The Point Cloud List remaining after projection filtering. |
