Engineering Contradiction Analysis
1Productivity
If manual handheld camera is used to photograph the target object from different viewing angles, then the photographing process can be completed, but the labor cost is high and the efficiency is low
Solution Approach 1:
The system automatically determines the physical position of the object and generates the virtual polyhedron without requiring manual modeling experience. The capturing apparatus autonomously identifies photographing angles and generates guidance information, eliminating the need for operators to have specialized modeling knowledge while maintaining high photographing efficiency.
Solution Approach 2:
The patent replaces the manual mechanical process of determining photographing angles with an automated computational system. The system uses computer vision and augmented reality technologies to automatically generate the virtual polyhedron and guide the photographing process, substituting manual operations with automated digital processing.
2Manufacturing precision
If more viewing angles are covered to build a more accurate physical model, then the model accuracy is improved, but the number of photos required increases leading to higher labor cost
Solution Approach 1:
The system performs preliminary determination of the object's physical position and pre-calculates the optimal photographing angles by generating a virtual polyhedron before the actual photographing process. This preliminary action allows the system to plan all necessary viewing angles in advance, ensuring complete coverage for accurate modeling while minimizing the actual photographing time required.
Solution Approach 2:
The system provides real-time feedback through the augmented reality display, showing the operator which faces of the virtual polyhedron have been captured and which remain. This feedback mechanism guides the operator to efficiently capture all necessary angles without redundancy, optimizing the balance between model accuracy and photographing time.
