Engineering Contradiction Analysis
1Measurement precision
If high-precision motion sensors are used to increase positioning precision, then positioning accuracy is improved, but hardware cost increases
Solution Approach 1:
The patent combines 3D imaging data from camera components with motion sensor data to achieve accurate positioning. By merging these two data sources, the system can achieve high positioning precision without relying solely on expensive high-precision motion sensors, thus resolving the contradiction between positioning accuracy and hardware cost.
Solution Approach 2:
The patent introduces 3D imaging data as an intermediary to bridge the gap between camera components and motion sensors. This intermediary data source enables the system to achieve accurate positioning through combination rather than relying on expensive motion sensors alone, effectively reducing hardware cost requirements while maintaining positioning precision.
2Measurement precision
If 3D imaging is combined with motion sensor data to improve positioning precision, then positioning accuracy is improved, but device complexity increases
Solution Approach 1:
The patent makes the control master computer perform multiple functions: it processes both 3D imaging data from camera components and motion sensor data, combines these data sources, and performs positioning calculations. By making the control master computer multi-functional, the patent achieves high positioning precision without adding complex dedicated hardware, thus resolving the contradiction between positioning accuracy and device complexity.
