3D Point Cloud Visualization for Precision Quality Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current CAV systems fail to enable users to observe point cloud data from various angles effectively for precise comparison, limiting the ability to improve manufactured objects by adjusting production criteria and procedures.
Innovation Solution
A system comprising an application server, client computers, and a database that acquires, edits, and displays point cloud data in a simulated three-dimensional space, allowing users to change the position and view of the point cloud through rotation and movement along axes, and switching between different views such as top, side, and front views.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If point cloud data is displayed in traditional CAV systems, then measurement and comparison functions are provided, but users cannot observe the point cloud from various angles for precise comparison
Solution Approach 1:
The patent transforms the traditional two-dimensional display of point cloud data into a three-dimensional simulated space environment. Users can rotate, translate, and view the point cloud from multiple angles (top, bottom, left, right, front, rear views) within this 3D space, enabling comprehensive observation that was impossible in conventional 2D displays while maintaining measurement precision through the virtual environment.
2Adaptability or versatility
If point cloud data is displayed in traditional CAV systems, then basic measurement functions are available, but the system lacks interactive visualization capabilities for quality improvement
Solution Approach 1:
The patent creates a virtual copy of the physical measurement environment within a computer-based simulated three-dimensional space. This virtual point cloud model preserves all geometric and spatial information while allowing unlimited interactive manipulation, rotation, and viewing from any angle, providing enhanced adaptability for quality control without compromising the accuracy of manufacturing measurements.

AI summary
A system for processing a point cloud in a simulated three-dimensional space includes an application server (1), client computers (3), and a database (5). The application server includes: a data acquiring module (10) for acquiring from the database point cloud data on an object measured by a measurement apparatus; a point cloud editing module (12) for editing the point cloud data to make the point cloud smooth and regular, and displaying different portions of the point cloud by using different colors; and a view changing device (11). The view changing device includes a position changing module (110) and a view changing module (111). The position changing module is used for changing a position of the point cloud in the three-dimensional space. The view changing module is used for changing a view to the point cloud in the three-dimensional space. A related method is also disclosed.
