Inspection Guide Image Data for 3D Model-Free Object Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current inspection methods require access to a 3D model of an object, which can be proprietary and subject to export compliance issues, and are time-consuming due to the need for manual overlaying and matching of inspection images with 3D models.
Innovation Solution
A method that determines guide image data from a determined orientation, allowing inspection without a 3D model by associating inspection image data with guide image data to determine object properties, reducing the need for 3D model access and streamlining the inspection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a 3D model is used for inspection, then measurement precision is improved, but loss of information occurs due to proprietary restrictions and export compliance issues
Solution Approach 1:
The patent extracts only the necessary visual information from the 3D model by creating 2D guide images that show inspection pathways and regions of interest. This allows the inspection system to obtain measurement precision without accessing or storing the complete proprietary 3D model, thereby resolving the contradiction between inspection accuracy and information loss.
Solution Approach 2:
Instead of using the original 3D model directly, the patent creates 2D guide images as simplified copies that contain only the essential inspection information. These guide images serve as sufficient representations for conducting inspections without requiring access to the full 3D model, thus preventing proprietary information loss while maintaining inspection capability.
2Measurement precision
If manual overlaying and matching of inspection images with 3D models is performed, then measurement precision is improved, but loss of time occurs due to the time-consuming process
Solution Approach 1:
The patent performs preliminary processing by pre-generating 2D guide images from the 3D model that contain embedded inspection pathways and reference information. This preliminary action eliminates the need for time-consuming manual overlaying and matching during actual inspections, as the guide images already contain the necessary alignment information, thus reducing inspection time while maintaining precision.
Solution Approach 2:
The patent replaces the manual mechanical process of overlaying and matching images with an automated system that uses pre-generated 2D guide images. The guide images contain encoded spatial information that enables automatic alignment and measurement, substituting the time-consuming manual operation with an automated image-processing approach that maintains precision while dramatically reducing inspection time.
3Measurement precision
If access to 3D model is required for inspection, then measurement precision is improved, but device complexity increases due to additional software and data management requirements
Solution Approach 1:
The patent extracts only the essential inspection information from the complex 3D model environment by generating standalone 2D guide images. This extraction eliminates the need for complex 3D model loading, rendering, and interaction software, thereby reducing device complexity while preserving the measurement precision needed for accurate inspections.
Solution Approach 2:
The patent replaces the need for expensive and complex 3D model access infrastructure with simple 2D guide images that can be generated once and reused multiple times. These guide images serve as lightweight, disposable inspection aids that eliminate the need for maintaining complex 3D modeling software and data management systems, thus reducing device complexity while maintaining inspection accuracy.

AI summary
A method for inspecting an object includes determining guide image data of the object from a determined orientation, the guide image data including a guide image pixel array and a pixel property for at least one guide image pixel in the guide image pixel array. The method also includes receiving inspection image data indicative of an inspection image and associating the inspection image data with the guide image data with a processor of a computing device. Additionally, the method includes determining a property of the object based on the guide image data and the associated inspection image data.
