Object Inspection Using Guide Images Instead of Proprietary 3D Models
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inspection methods require access to a 3D model of an object, which may contain proprietary information and are time-consuming due to manual overlaying and matching with 3D models.
Innovation Solution
A method that determines guide image data from a determined orientation of the object, allowing inspection without the 3D model by associating inspection image data with guide image data to determine object properties, using pixel properties and user inputs to analyze features like cracks or chips.
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 increases due to proprietary 3D model data requirements
Solution Approach 1:
The patent extracts only the necessary visual inspection data from the 3D model by generating guide image data that represents the object's surface features without requiring access to the complete proprietary 3D model. This allows inspection to proceed using only the extracted guide image data, eliminating the need to share or store sensitive 3D model information while maintaining inspection accuracy.
Solution Approach 2:
The patent creates a simplified copy of the 3D model's essential features in the form of guide image data. This copy contains sufficient information for inspection purposes (surface geometry, features of interest) but lacks the proprietary details of the original 3D model, allowing accurate inspection without compromising information security.
2Measurement precision
If a 3D model is used for inspection, then measurement precision is improved, but productivity decreases due to manual overlaying and matching processes
Solution Approach 1:
The patent performs preliminary actions by pre-generating guide image data from the 3D model before the actual inspection process. This guide image data is prepared in advance and stored for reuse, eliminating the need to perform time-consuming overlaying and matching operations during each inspection. The preliminary generation of guide images significantly accelerates subsequent inspections while maintaining measurement precision.
3Ease of operation
If guide image data is determined from a determined orientation, then ease of operation is improved, but device complexity increases due to orientation determination requirements
Solution Approach 1:
The patent introduces guide image data as an intermediary that bridges the complex orientation determination process and the simple inspection operation. The system determines the object's orientation and uses this information to generate guide images from the appropriate viewpoint. Once generated, these guide images serve as a simplified interface for inspection, hiding the complexity of orientation calculations from the user while maintaining operational simplicity.

AI summary
A method for inspecting an object includes determining a first inspection package that includes a first inspection image of the object and a first designation. The method includes determining data indicative of a second inspection package that includes a second inspection image of the object and a second designation. The method includes determining a first property of the object based on the first inspection image of the object, one or more properties maps of the object, and the first designation. The method includes determining a second property of the object based on the second inspection image of the object, the one or more properties maps of the object, and the second designation. The method includes displaying the first property and the second property or displaying data indicative of a comparison of the first property with the second property.
