Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional graphic display apparatuses cannot superimpose images and graphs by setting a display range corresponding to the size of a subject in the image, limiting their ability to accurately display both image and graphic together.
Innovation Solution
A graphic display apparatus with a display unit, reference object length storage, image storage, image display control, specified image part setting, coordinate system setting, and graphic display control units that associate reference object parts with their actual lengths, allowing users to superimpose a coordinate system and display range based on the actual length of image parts, enabling the overlay of images and graphics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional graphic display apparatuses display images with scale marks, then the actual size of the image can be indicated, but the image and graphic cannot be superimposed by setting a display range corresponding to the size of a subject
Solution Approach 1:
The system performs preliminary detection of reference objects and storage of their actual lengths before the superimposition operation. When a user wants to superimpose a graphic, the system has already prepared the reference object database with associated actual lengths, enabling quick retrieval and application without complex real-time measurements.
Solution Approach 2:
The patent introduces a coordinate system as an intermediary between the image and the graphic to be superimposed. This coordinate system serves as a mediator that translates the actual length information of reference objects into display coordinates, allowing accurate superimposition without directly manipulating the image or graphic data themselves.
2Measurement precision
If the display range is set to match the actual size of a subject, then accurate superimposition of image and graphic is achieved, but the system requires detection and storage of reference object lengths
Solution Approach 1:
Instead of requiring direct measurement of every reference object, the system creates a database copy of reference objects with their associated actual lengths. This copied information can be retrieved and applied to multiple images without requiring real-time measurement, maintaining measurement precision while reducing system complexity through pre-computed data storage.
Solution Approach 2:
The reference object database serves multiple functions: it provides measurement references for various subjects, enables coordinate system establishment, and supports superimposition operations. This multi-functional approach reduces the need for separate measurement and calculation systems, thereby reducing overall device complexity while maintaining precision.
3Manufacturing precision
If a coordinate system is superimposed on the image based on actual length, then the graphic can be accurately displayed on the image, but the system requires association of reference object parts with actual lengths
Solution Approach 1:
The patent segments the reference object into specific parts with identifiable actual lengths (e.g., separating the length of a building from its width, or dividing a reference object into measurable segments). This segmentation allows the system to associate specific dimensional information with specific parts, enabling precise coordinate system establishment without requiring complete measurement of the entire object, thus reducing complexity.
Solution Approach 2:
The system stores reference objects with their actual lengths as parameters in a database. When establishing a coordinate system, the system retrieves and applies these stored parameter values (actual lengths) to calculate the appropriate scale and position. This parameter-based approach maintains manufacturing precision by using accurate reference values while simplifying the mechanism through automated parameter retrieval and application.
