Grid-Aligned Contour Correction for Digital Twin Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The abstraction of structural object shapes in digital twin simulations often results in reduced visibility and complex vision due to simplified representations, leading to potential installation errors in actual plants.
Innovation Solution
An information presentation device with a contour extraction unit, abstraction processing unit, and contour correction unit that extracts, abstracts, and corrects contour lines to align with a grid system, preventing visibility reduction and improving aesthetic properties during display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If abstraction processing is applied to simplify facility shapes in digital twin simulations, then development costs are reduced, but visibility and visual clarity are compromised
Solution Approach 1:
The patent introduces a grid reference system as an additional dimensional layer overlaid on abstracted facility representations. This grid system provides spatial orientation and structural context that compensates for the loss of visual detail caused by abstraction, enabling users to understand facility layout and relationships without requiring detailed visual representations
Solution Approach 2:
The patent employs contour lines as intermediary elements that bridge the gap between abstracted facility shapes and their spatial relationships. These contour lines serve as visual mediators that convey structural information without requiring detailed visual representation of individual facility components, thus maintaining visibility while preserving abstraction benefits
2Device complexity
If abstraction processing is applied to simplify facility shapes, then development complexity is reduced, but aesthetic properties and visual clarity deteriorate
Solution Approach 1:
By overlaying a grid reference system, the patent adds a dimensional framework that imposes order and structure on abstracted representations. This grid layer provides aesthetic organization and visual clarity without increasing the complexity of the underlying abstraction processing
Solution Approach 2:
The patent modifies the visual representation parameters by introducing standardized grid lines and contour line conventions. These parameter changes enhance the aesthetic properties and visual clarity of abstracted facilities through consistent visual patterns, while the actual abstraction processing complexity remains low

AI summary
An information presentation device according to an embodiment includes a contour extraction unit, an abstraction processing unit, and a contour correction unit. The contour extraction unit extracts a contour of each structural object included in data showing a layout of a plurality of structural objects. The abstraction processing unit abstracts a contour of each structural object extracted by the contour extraction unit and draws the abstracted contour on a plane grid surface in which grid lines in two directions orthogonal to each other are drawn. The contour correction unit corrects, among contour lines to constitute a contour abstracted by the abstraction processing unit, a contour line deviating from both of the grid lines in the two directions so as to match a grid line in at least one direction of the grid lines in the two directions.
