Engineering Contradiction Analysis
1Measurement precision
If specialized hardware like LIDAR sensors or RGB-D cameras is used for data collection, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent uses a virtual bounding body that copies the function of physical depth sensing hardware. This virtual structure processes 2D images to generate depth information and spatial relationships, replacing the need for actual LIDAR or RGB-D cameras while maintaining measurement precision for 3D reconstruction.
Solution Approach 2:
The patent replaces mechanical/optical depth sensing mechanisms with computational methods. Instead of using physical sensors to directly measure depth, the system uses image processing algorithms on virtual bounding bodies to calculate spatial information, thereby reducing hardware complexity while preserving measurement capabilities.
2Power
If high-performance independent graphics card is configured for 3D reconstruction processing, then processing power is improved, but device complexity increases
Solution Approach 1:
The patent creates a virtual bounding body that replicates the 3D reconstruction process without requiring high-performance graphics hardware. This virtual structure processes images through computational algorithms, generating 3D models on standard terminals without needing powerful independent graphics cards.
Solution Approach 2:
The patent changes the computational parameters and processing approach to be compatible with standard terminal devices. By adjusting algorithm complexity and processing methods, the system achieves effective 3D reconstruction on devices without high-performance graphics hardware, maintaining processing capability while reducing hardware requirements.
3Measurement precision
