Innovation Solution
An apparatus with displays outside the stopping area that change display patterns according to vehicle and camera specifications, using a control terminal connected to an IC tag and detecting unit to adjust display positions and perform calibration, allowing for smooth calibration of vehicles with varying specifications using a limited number of lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple calibration lines are set up to handle different vehicle and camera specifications, then calibration capability for various specifications is improved, but device complexity and space requirements increase
Solution Approach 1:
The patent implements a universal calibration line where the display device can present different display patterns (first pattern for right-side driver seats, second pattern for left-side driver seats) to accommodate different vehicle and camera specifications. This multi-functionality allows a single calibration line to handle various specifications without requiring multiple dedicated lines, thereby reducing device complexity while maintaining adaptability.
2Adaptability or versatility
If multiple calibration lines are set up to handle different vehicle and camera specifications, then calibration capability for various specifications is improved, but loss of time and operational efficiency decrease
Solution Approach 1:
The display device dynamically changes the display pattern based on the detected vehicle and camera specifications. The control device receives specification information and automatically switches between different display patterns without requiring manual reconfiguration. This dynamic adaptation eliminates the time loss associated with setting up different calibration lines for different specifications, while maintaining full calibration capability.
3Measurement precision
If display patterns are fixed for specific specifications, then calibration precision for those specifications is improved, but adaptability to different specifications worsens
Solution Approach 1:
The system changes the display pattern parameters (first pattern or second pattern) based on the detected specifications of the vehicle and camera. By adjusting the display pattern parameters to match the specific calibration requirements, the system maintains high calibration precision for each specification while remaining adaptable to different vehicle and camera configurations through automated parameter selection.
