3D Ship Situation Display for Collision Risk Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices and methods for displaying ship information do not provide a comprehensive view of the situation around a ship, lacking discrimination between different ships and failing to indicate potential collision risks effectively.
Innovation Solution
An image generating device that includes a data acquiring part, a three-dimensional object placing part, a camera setting part, and an indication image generating part to create a three-dimensional image of a ship's surroundings, allowing for bird's-eye view, camera following modes, and integration with two-dimensional images to enhance situational awareness and collision risk indication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a three-dimensional image is generated to provide comprehensive ship information, then the completeness of situational awareness is improved, but the computational complexity and processing time increase
Solution Approach 1:
The patent transitions from two-dimensional ship position data to three-dimensional visualization by placing 3D ship objects in a virtual 3D space corresponding to 2D positions, enabling comprehensive situational awareness through dimensional expansion
Solution Approach 2:
The patent creates virtual copies of ships as three-dimensional objects in a simulated environment, allowing comprehensive analysis of ship situations without requiring complex real-time processing of actual ship data
2Quantity of substance
If multiple ships are displayed without discrimination, then the quantity of ship information is improved, but the clarity of individual ship identification deteriorates
Solution Approach 1:
The patent applies different visual properties to different ships including unique colors, sizes, and graphical symbols that represent specific ship characteristics, enabling clear discrimination while displaying multiple ships simultaneously
Solution Approach 2:
The patent uses color variations to differentiate between multiple ships and to indicate collision risks, with different colors representing different ship identities and risk levels
3Device complexity
If traditional two-dimensional display is used, then the simplicity of the display system is maintained, but the ability to indicate collision risks effectively deteriorates
Solution Approach 1:
The patent adds vertical dimension and spatial depth to the display system, positioning ships at different heights and depths to represent collision risks, where spatial relationships provide intuitive risk indication while maintaining relatively simple system architecture
Solution Approach 2:
The patent uses color coding to indicate collision risks, with different colors representing different risk levels, enabling effective risk communication without requiring complex additional display components

AI summary
The present disclosure provides an image generating device capable of making a situation around a ship comprehensive. The image generating device includes processing circuitry. The processing circuitry acquires ship data indicative of a two-dimensional position of a ship on a water surface. The processing circuitry places a three-dimensional ship object indicative of the ship, at a position of a virtual water surface in a virtual three-dimensional space corresponding to a two-dimensional position of the ship. The processing circuitry sets a virtual camera in a bird's-eye view mode in which the three-dimensional ship object is looked down obliquely from a position higher than the three-dimensional ship object. The processing circuitry generates a three-dimensional image in which a sight within a field of view of the virtual camera including the three-dimensional ship object is drawn. The processing circuitry generates an image for indication including the three-dimensional image.
