3D Data Display Device for Plant Component Spatial Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plant operation training devices require advanced operations to determine the spatial position of parts, making it difficult for operators to easily recognize the spatial positions of components within a plant.
Innovation Solution
A three-dimensional data display device that includes a rendering unit, identification unit, and viewpoint control unit to move a viewpoint along an annular movement route with a sight line directed toward a point of interest, allowing for easy recognition of spatial positions by rendering the entire external appearance of a point of interest as two-dimensional data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operator uses a conventional plant operation training device to recognize the spatial position of parts, then the operator can obtain spatial position information, but the operator requires advanced operation skills and complex procedures (moving avatar around the part) to recognize the entire external appearance of a part
Solution Approach 1:
The patent transitions from three-dimensional virtual space navigation to two-dimensional planar display by projecting the annular movement route onto a flat surface. This dimensional reduction allows operators to view the entire external appearance of parts and spatial relationships in a single two-dimensional view, eliminating the need for complex three-dimensional avatar manipulation while maintaining comprehensive spatial recognition capabilities
2Loss of information
If the operator manually moves the avatar around a part in three-dimensional space to view the entire external appearance, then the operator can recognize the part's spatial position, but the operation becomes time-consuming and requires advanced skills
Solution Approach 1:
The system pre-calculates and displays the complete annular movement route showing all possible viewing positions around a part before the operator begins observation. This preliminary presentation of the entire movement path allows operators to immediately understand the complete external appearance and spatial position without sequentially navigating through each viewpoint, significantly reducing recognition time and skill requirements
3Difficulty of detecting and measuring
If the system displays only the current viewpoint in three-dimensional space, then the rendering is simple, but the operator cannot easily understand the spatial relationships and external appearance of parts
Solution Approach 1:
The patent introduces a two-dimensional planar display as an intermediary between the three-dimensional virtual space and the operator's perception. This intermediate representation projects the annular movement route and part positions onto a flat surface, making spatial relationships and external appearances immediately visible and understandable without requiring operators to mentally process complex three-dimensional navigation data

AI summary
A three-dimensional data display device includes an identification unit which is configured to identify a point of interest which is a point on three-dimensional data, a viewpoint control unit which is configured to move a viewpoint along an annular movement route surrounding the point of interest with a sight line directed toward the point of interest, and a rendering unit which is configured to obtain two-dimensional data by rendering the three-dimensional data on the basis of a viewpoint.
