Solution Overview
Problem
Existing 3D modeling methods face challenges in accurately capturing images of a 3D object at appropriate positions and attitudes, leading to inefficient workloads and processing loads due to insufficient or excessive imaging.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple images are captured from various directions for 3D modeling, then the accuracy of 3D data is improved, but the imaging workload and processing time increase
Solution Approach 1:
The system performs preliminary 3D modeling based on initially captured images to generate a preliminary 3D model before the actual imaging operation. This preliminary model is then used to determine optimal imaging positions and attitudes, allowing the system to plan the imaging sequence in advance and avoid unnecessary captures.
Solution Approach 2:
The system continuously updates the 3D model based on captured images and uses this updated model to provide feedback on imaging quality. The evaluation unit assesses whether captured images contribute sufficiently to 3D model accuracy, and the control unit adjusts imaging positions and attitudes based on this feedback to optimize the imaging process.
2Manufacturing precision
If images are captured at more appropriate positions and attitudes, then 3D data accuracy is improved, but it becomes difficult for operators to identify appropriate positions and attitudes
Solution Approach 1:
The system introduces an intermediary evaluation mechanism that automatically determines whether captured images are sufficient for accurate 3D modeling. The evaluation unit acts as a mediator between the captured images and the 3D modeling process, providing objective feedback on imaging quality without requiring operator expertise in assessing 3D modeling requirements.
Solution Approach 2:
The system replaces the manual judgment mechanism (operator's ability to identify appropriate positions) with an automated computational evaluation system. The evaluation unit uses algorithms to assess imaging quality and determine whether captured images contribute sufficiently to 3D model accuracy, substituting human judgment with automated analysis.
3Productivity
If fewer images are captured to reduce workload, then processing time is reduced, but 3D data accuracy may be compromised
Solution Approach 1:
The system implements a dynamic imaging strategy where the control unit determines the minimum necessary number of images required for accurate 3D modeling based on the evaluation feedback. Instead of capturing a fixed large number of images or a fixed small number, the system captures exactly the necessary amount - no more, no less - optimizing the balance between workload and accuracy.
