Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for three-dimensional modeling, such as those described in Patent Literature 1, are limited as they require a predetermined inspection subject and cannot provide a user with a true three-dimensional model, only projecting data in two-dimensional coordinates.
Innovation Solution
An information processing device and method that obtain three-dimensionally scanned data, perform object detection, and search among multiple three-dimensional model candidates to identify and output a corresponding three-dimensional model, enabling the creation and display of a three-dimensional representation of scanned objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If three-dimensional scanned data is obtained by sensing one or more objects, then the ability to handle unknown subjects is improved, but the complexity of object detection and model identification increases
Solution Approach 1:
The identifying process is segmented into two distinct sub-processes: object detection (identifying what objects are present) and model searching (finding corresponding models). This segmentation allows the system to handle unknown subjects by detecting objects first, then separately searching for models, reducing the overall complexity of the combined task.
Solution Approach 2:
The object detecting process acts as an intermediary between the raw three-dimensional scanned data and the model searching process. It extracts object information from the scanned data and passes it to the searching process, which then matches objects with models. This intermediary step simplifies the overall system by breaking down the complex task of identifying models for unknown subjects into manageable stages.
2Measurement precision
If object detection and model searching processes are implemented, then the accuracy of three-dimensional model identification is improved, but the processing time increases
Solution Approach 1:
The object detecting process performs preliminary action by identifying and extracting object information from the three-dimensional scanned data before the model searching process begins. This preliminary detection reduces the search space and allows the subsequent model matching to be more efficient, balancing accuracy with processing time.
3Device complexity
If two-dimensional projection display is used, then the simplicity of display is improved, but the ability to provide true three-dimensional model information is worsened
Solution Approach 1:
The system transitions from two-dimensional projection display to three-dimensional model output. Instead of flattening the three-dimensional scanned data into 2D coordinates, the system identifies and outputs actual three-dimensional models that preserve spatial information, thereby eliminating the loss of three-dimensional model information while maintaining manageable complexity through automated identification processes.
