Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If depth information is corrected using conventional systems, then positioning accuracy improves, but calculation load and communication requirements increase
Solution Approach 1:
The patent extracts only the necessary distortion information from the imaging device and transmits it to the information processing device, rather than transmitting complete raw image data. This selective extraction reduces communication requirements and calculation load while maintaining the ability to correct depth information for accurate positioning.
Solution Approach 2:
The distortion information is pre-calculated and stored in the imaging device before depth correction is needed. This preliminary preparation allows the information processing device to perform quick corrections without heavy real-time computation, reducing calculation load during actual operation.
2Measurement precision
If depth information is corrected using conventional systems, then positioning accuracy improves, but communication requirements increase
Solution Approach 1:
The system extracts only the essential distortion parameters from the imaging device and transmits them to the information processing device. This selective transmission reduces communication bandwidth requirements while preserving the information needed for accurate depth correction and positioning.
3Measurement precision
If distortion information is stored in the imaging device, then depth correction accuracy improves, but device complexity increases
Solution Approach 1:
The imaging device autonomously calculates and stores its own distortion information based on its optical characteristics and imaging element arrangement. This self-service capability allows the device to maintain accuracy without requiring external calibration equipment or complex external processing systems.
