Subsea Platform Visualization Using Synthetic Models
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Underwater visibility limitations due to water absorption and turbidity, combined with the use of 2-D monitors that restrict the pilot's field of view, make it difficult to interpret spatial surroundings when operating subsea platforms like ROVs.
Innovation Solution
A method that utilizes a database to generate visualization data using synthetic models, combining this with camera image data to create an image structure, which includes augmented reality views, such as transparent cuboids, to provide dedicated views for operators, enhancing their understanding of the environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If camera image data is used to visualize objects underwater, then operator awareness of spatial surroundings is improved, but image quality deteriorates due to water absorption and turbidity
Solution Approach 1:
The patent creates virtual copies of real objects using synthetic models that replicate the appearance and spatial characteristics of actual underwater objects. These synthetic models are rendered to match camera perspectives and combined with real camera feeds, providing reliable spatial information without being degraded by poor underwater visibility conditions
Solution Approach 2:
The patent merges real camera image data with synthetic model data to create a composite visualization. The synthetic models are rendered to match the camera's field of view and perspective, then overlaid or blended with the actual camera feed, combining the reliability of synthetic rendering with the real-time accuracy of actual sensor data
2Device complexity
If 2-D monitors are used for display, then device complexity is reduced, but operator's field of view and spatial understanding are limited
Solution Approach 1:
The patent transitions from 2-D monitor displays to 3-D immersive visualizations that provide depth perception and spatial context. By rendering synthetic models in three dimensions and combining them with real camera feeds, the system creates a more intuitive spatial representation that helps operators understand the underwater environment's depth and object positions without requiring complex multi-monitor setups
