Solution Overview
Problem
Existing three-dimensional reconstruction systems face challenges in accurately capturing detailed information of moving objects within a space without increasing costs, as additional sensors are needed to maintain detection range and resolution, leading to potential information gaps.
Innovation Solution
A three-dimensional reconstruction system that integrates data from fixed and movable sensors, where the movable sensor automatically adjusts its position and posture to maintain detection of the attention part, reducing the need for additional sensors and maintaining detailed information capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If additional sensors are set along moving paths of the attention part to maintain detection range and resolution, then the completeness of three-dimensional information is improved, but the system cost increases
Solution Approach 1:
The patent applies the dynamics principle by making the sensor movable instead of fixed. The sensor can automatically adjust its position and posture to track the attention part as it moves within the space. This dynamic capability allows a single sensor to maintain detection of moving targets without requiring multiple fixed sensors along potential movement paths, thereby reducing system cost while maintaining information completeness.
Solution Approach 2:
The movable sensor serves multiple functions: it can detect any part of the space where the attention part moves, replacing what would otherwise require multiple dedicated sensors positioned at different locations. This multi-functionality allows one sensor to perform the work of several fixed sensors, reducing the overall system cost while maintaining complete three-dimensional information coverage.
2Device complexity
If a fixed sensor is used to capture the attention part, then the system cost is reduced, but the detection precision deteriorates when the attention part moves outside the detection range
Solution Approach 1:
The sensor is designed to be movable with automatic tracking capability. When the attention part moves within the space, the sensor automatically adjusts its position and orientation to keep the attention part within its detection range. This dynamic tracking ensures that detection precision is maintained at all times, equivalent to having multiple fixed sensors, while using only a single sensor to reduce system cost.
Solution Approach 2:
The system employs feedback mechanisms where the sensor continuously monitors the position of the attention part and automatically adjusts its own position and posture in response. This closed-loop control ensures that the attention part remains within the optimal detection range, maintaining high measurement precision without requiring additional sensors or increasing system complexity.
