AR Tidal Current Display Superimposition for Marine Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional augmented reality navigation systems fail to effectively display tidal current information for marine vessels, as they rely on external sources for tidal current data and lack the capability to obtain and display this information from external sources on their own display screens.
Innovation Solution
An augmented reality-based tidal current display apparatus that includes an image sensor, tidal current information terminal, selection unit, position calculation unit, and superimposition unit to receive, process, and display tidal current information on a display screen, allowing for the visualization of tidal currents' positions, directions, and speeds relative to the vessel's location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional AR navigation systems use on-board sensors to detect surrounding information, then the system can display image information and ship information, but it cannot display tidal current information because tidal currents cannot be detected by on-board equipment
Solution Approach 1:
The patent introduces an external base station as an intermediary to provide tidal current information to the vessel. Instead of attempting to detect tidal currents directly with on-board sensors, the system uses communication equipment to receive pre-measured tidal current data from external bases, thereby solving the detection limitation without adding complex sensing equipment to the vessel.
Solution Approach 2:
The patent replaces the mechanical/sensor-based detection approach with a communication-based information delivery system. Rather than using physical sensors to measure tidal currents, the system substitutes this with electronic communication channels that transmit tidal current information from external measurement bases to the vessel's display system.
2Loss of information
If tidal current information is obtained from external bases through communication equipment, then tidal current data can be received, but conventional AR systems cannot display this information on their AR display screens
Solution Approach 1:
The patent enhances the AR display system's versatility by enabling it to handle multiple types of information simultaneously - not only image data from cameras and positional data from radar, but also tidal current information from external communication bases. The display system is adapted to integrate and visualize diverse data sources including tidal current direction, speed, and position information overlaid on the AR interface.
Solution Approach 2:
The system dynamically adapts the AR display to accommodate tidal current information by adjusting how information is presented. The display can show tidal current data in various formats (arrows, numerical values, color-coded indicators) and can prioritize or minimize different information types based on navigation context, making the display system flexible and adaptive to different operational scenarios.
3Reliability
If vessel navigating personnel rely on conventional navigation methods, then they can operate the vessel, but they are unaware of tidal current influence and must choose sub-optimal courses
Solution Approach 1:
The patent implements a feedback mechanism that continuously provides tidal current information to the navigating personnel through the AR display. The system shows real-time or near-real-time tidal current direction, speed, and position relative to the vessel, enabling navigators to understand how tidal currents are affecting the vessel and to adjust their course accordingly for optimal navigation.

AI summary
An augmented reality based tidal current display device for superimposing tidal current information on an image displayed on a display screen includes an image information terminal configured to receive the image captured by an image sensor, and output image data for displaying on the display screen; an image sensor information terminal configured to receive and store image sensor information of the image sensor; a tidal current information terminal configured to receive and store tidal current information of the water surface; and processing circuitry configured to: select tidal currents, calculate a corresponding display position and direction of each selected tidal current on the display screen based on the tidal current information and the image sensor information, generate a symbol to indicate the corresponding display position and direction on the display screen, and superimpose the symbol at a respective display position to the corresponding display position on the image.
