Eyeglass Fitting Parameter Measurement Device with Synchronized Image Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyeglass fitting parameter measurement devices face challenges in accurately measuring parameters due to the lack of association between front and lateral images, leading to unstable and time-consuming processes, and require manual analysis, which results in low reproducibility and inefficiency.
Innovation Solution
An eyeglass fitting parameter measurement device that displays both front and lateral images of an examinee wearing an eyeglass frame, with a position information detection unit to determine eye or frame positions, and a display control unit to provide correspondence indications, allowing for synchronized movement and magnification correction to ensure accurate parameter measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If front and lateral images are displayed separately without association, then the measurement process becomes simpler, but measurement precision and reproducibility deteriorate
Solution Approach 1:
The patent combines front and lateral images into a single integrated display interface, showing both images simultaneously with their respective measurement parameters. This merging allows examiners to compare and correlate features across both views without switching between separate displays, thereby improving measurement precision while maintaining process simplicity.
Solution Approach 2:
The patent introduces correspondence indications as visual markers that link specific features between the front and lateral images. These markers act as intermediaries that help examiners understand the spatial relationship between features in different views, enhancing measurement accuracy without adding operational complexity.
2Device complexity
If manual analysis of images is performed, then device complexity is reduced, but productivity and time consumption worsen
Solution Approach 1:
The system automatically performs image analysis and generates measurement parameters without requiring manual intervention. The automated detection of eye positions, frame positions, and other fitting parameters significantly improves productivity while keeping the device architecture relatively simple, as the automation is integrated into the existing imaging and display system.
3Measurement precision
If correspondence indications are provided between images, then measurement precision improves, but device complexity increases
Solution Approach 1:
The patent uses visual copying of position information by displaying correspondence indications that replicate the spatial relationships between features in front and lateral images. These indications are generated automatically through image processing algorithms that copy coordinate information between views, improving measurement precision without requiring complex manual alignment procedures.

AI summary
There is an provided eyeglass fitting parameter measurement device including: a display control unit that displays a front image of an examinee wearing an eyeglass frame and a lateral image of the examinee wearing the eyeglass frame on a display part; and a position information detection unit that detects position information for determining the positions of the examinee's eyes or the eyeglass frame based on one of the front image and the lateral image. The display control unit provides a correspondence indication corresponding to the position information detected by the position information detection unit in a display area for the other of the front image and the lateral image based on the position information.
