Water-Surface Display Positioning for Wave-Induced Posture Shifts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image generating devices for water-surface movable bodies fail to provide an easy-to-view and natural impression of the surrounding situation, particularly due to the lack of consideration for changes in the imaging device's posture caused by waves, leading to unnatural display positions of target objects.
Innovation Solution
An image generating device with a configuration that includes a position acquiring module, a posture acquiring module, an additional display information acquiring module, and a display data generating module, which generates three-dimensional display data to superimpose graphics on the water surface, maintaining a natural and intuitive representation of the situation despite changes in the device's posture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the target object display item is displayed at the points on the image corresponding to the positional information on the target object, then the positional accuracy is improved, but the natural impression deteriorates when the water-surface movable body is shaken by waves
Solution Approach 1:
The patent applies the dynamics principle by making the display position adaptive to changing conditions. The system dynamically adjusts the display position of target objects based on the detected posture of the water-surface movable body. When the body is stationary, objects are displayed at their actual corresponding positions on the image. When shaking is detected, the display positions are adjusted to maintain natural spatial relationships, thus resolving the contradiction between positional accuracy and natural impression under varying conditions.
2Ease of operation
If the display position is fixed based on positional information, then the ease of operation is improved, but the adaptability to posture changes deteriorates
Solution Approach 1:
The system transitions from a static display position approach to a dynamic one by continuously monitoring the posture of the water-surface movable body and adjusting display positions accordingly. This dynamic adaptation maintains ease of viewing while accommodating posture changes, as the display system automatically recalibrates to present target objects in their correct spatial context regardless of the body's orientation or movement.
Solution Approach 2:
The patent implements feedback by detecting the posture of the water-surface movable body and using this information to adjust the display positions of target objects. The system continuously monitors posture changes and feeds this information back to the display positioning mechanism, enabling real-time adjustments that maintain both ease of operation and adaptability to changing conditions.
3Device complexity
If the target object display item is displayed without considering posture changes, then the device complexity is reduced, but the reliability of the display deteriorates
Solution Approach 1:
The patent introduces a feedback mechanism where the posture of the water-surface movable body is detected and used to adjust display positions. This feedback loop adds minimal complexity to the display system while significantly improving reliability, as the system automatically compensates for posture changes to maintain accurate and natural target object positioning without requiring complex manual intervention.
