Solution Overview
Problem
Conventional methods for generating three-dimensional models of objects using three-dimensional measuring machines face challenges such as the need for pre-existing CAD data and the inefficiency of repeated measurements when objects have complex surface properties or varying orientations, leading to errors and increased time and effort in model creation.
Innovation Solution
A model generating device that uses a three-dimensional measuring machine to measure objects from multiple virtual positions, extracts and integrates measurement data to create a three-dimensional model, allowing for generation of models without CAD data and reducing the number of necessary measurements by using a temporary model and optimizing data integration.

Engineering Contradiction Analysis
1Productivity
If a three-dimensional model is generated using CAD data, then the model generation process is simplified and does not require multiple measurements, but the method cannot account for actual surface properties and may produce errors when surface properties differ from CAD specifications
Solution Approach 1:
The patent creates a three-dimensional model by copying and integrating measurement data from multiple objects measured in different orientations. Instead of relying on CAD data copies, it uses actual measurement data copies from multiple perspectives to reconstruct the complete object model, ensuring surface properties are accurately captured.
Solution Approach 2:
The patent transitions from single-orientation measurement to multi-orientation measurement by measuring objects in different dimensional orientations (e.g., rotated positions). This dimensional approach allows comprehensive capture of surface properties that cannot be obtained from a single measurement perspective.
2Measurement precision
If repeated three-dimensional measurements are performed from various perspectives to capture all surfaces, then complete surface coverage is achieved, but the time and effort required for model creation increases dramatically
Solution Approach 1:
The patent merges measurement data from multiple objects measured in different orientations into a single integrated three-dimensional model. By combining data from multiple measurement sessions and orientations, it achieves complete surface coverage without requiring exhaustive repeated measurements of the same object from every possible angle.
Solution Approach 2:
The patent performs preliminary measurements on multiple objects in various orientations beforehand, storing the measurement data for later integration. This preliminary action allows the complete three-dimensional model to be constructed more efficiently when needed, avoiding the need for time-consuming repeated measurements at the time of model generation.
3Adaptability or versatility
If measurement data from multiple objects in different orientations are integrated, then a complete three-dimensional model can be generated without CAD data, but the data integration process becomes more complex
Solution Approach 1:
The patent uses an intermediary processing system that standardizes and coordinates measurement data from multiple objects and orientations. This intermediary layer manages the complexity of data integration by providing a unified framework for combining measurements, making the process more manageable despite the diverse input data sources.
Solution Approach 2:
The patent creates a universal measurement and integration system that can handle objects in various orientations and positions. The system is designed to process measurement data from multiple sources and orientations using a single integrated approach, making it versatile for different object types while managing integration complexity through standardized procedures.
