Engineering Contradiction Analysis
1Productivity
If multiple imaging units are used to improve coverage and efficiency, then productivity increases, but the complexity of coordinating and calibrating multiple units increases
Solution Approach 1:
The patent introduces a calibration unit as an intermediary component that mediates between multiple imaging units. This calibration unit receives orientation information from each imaging unit, performs calibration computations, and outputs corrected orientation information. By isolating the calibration functionality in a separate intermediary module, the patent simplifies the overall system architecture while enabling multi-unit coordination.
Solution Approach 2:
The patent applies preliminary calibration actions before the actual imaging process. The calibration unit pre-processes orientation information from imaging units, establishing accurate spatial relationships in advance. This preliminary calibration ensures that when multiple imaging units operate together, their data can be properly integrated without requiring complex real-time coordination.
2Measurement precision
If calibration processing is performed for each imaging unit to maintain accuracy, then measurement precision is improved, but processing time and computational load increase
Solution Approach 1:
The patent merges the calibration processing of multiple imaging units into a single integrated operation. Instead of treating each imaging unit's calibration independently and sequentially, the calibration unit processes all orientation information simultaneously, combining multiple calibration computations into one unified operation. This merging approach maintains high measurement precision while significantly reducing total processing time.
Solution Approach 2:
The calibration unit creates a standardized calibration result that can be applied across multiple imaging units. By computing a universal calibration transformation based on the first captured image and first three-dimensional shape information, the system avoids redundant calculations for each subsequent imaging unit, thereby reducing processing time while maintaining accuracy.
3Manufacturing precision
If comprehensive calibration is performed to ensure high accuracy, then manufacturing precision is improved, but the workload and processing volume increase
Solution Approach 1:
The patent extracts only the essential calibration information needed for accurate 3D modeling from the comprehensive calibration process. The calibration unit identifies and processes only the critical orientation parameters and spatial relationships, discarding redundant calibration data. This extraction approach maintains manufacturing precision while reducing the quantity of processing data and computational workload.
Solution Approach 2:
The calibration unit applies different levels of processing precision to different aspects of the calibration data. Rather than uniformly processing all calibration information at maximum precision, the system applies high precision only to critical parameters that directly affect 3D modeling accuracy, while using lower precision for less critical parameters. This local quality approach maintains overall manufacturing precision while reducing total processing volume.
