Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensing technologies face challenges in accurately inspecting large structures due to the limitations of narrow-angle data providing detailed shape information but lacking context within the overall inspection range, and wide-angle data lacking detail, leading to incomplete or inaccurate inspections.
Innovation Solution
An information processing apparatus that integrates narrow and wide-angle sensing data, synchronizing sensor positions and orientations to associate detailed shape data with broader context, enabling precise comparison and inspection of target objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If narrow-angle sensing data is used to capture detailed shape information, then measurement precision is improved, but the area of inspection coverage deteriorates
Solution Approach 1:
The patent segments the inspection task into multiple narrow-angle sensing measurements taken from different positions and orientations. Each measurement captures detailed shape information of a specific portion, and the system systematically divides the overall inspection space into multiple sub-regions that are sequentially measured and then integrated to form a complete wide-range shape model.
2Area of stationary object
If wide-angle sensing data is used to capture overall shape information, then the area of inspection coverage is improved, but measurement precision deteriorates
Solution Approach 1:
The patent merges multiple narrow-angle sensing data sets into a unified wide-range shape model. By combining measurements from multiple positions and orientations, the system achieves both comprehensive coverage and high precision, as each narrow-angle measurement contributes detailed information to the corresponding portion of the overall model.
3Measurement precision
If multiple sensing data sets are collected and integrated, then measurement precision and coverage are improved, but device complexity increases
Solution Approach 1:
The patent creates a digital copy or virtual model of the target object's shape by integrating sensing data. This digital replica allows for repeated analysis, comparison, and verification without requiring physical re-measurement, thereby reducing the complexity of handling multiple data sets while maintaining high measurement precision.
