Solution Overview

Problem

In stereo three-dimensional measurement systems, users face difficulties in determining whether measurement results meet reliability criteria, as they cannot visually identify areas that do not satisfy these criteria from captured images or measurement results.

Innovation Solution

An image processing system that includes a measurement part, a reliability calculation part, and a display part to calculate and visually represent areas not meeting reliability criteria, allowing users to assess the reliability of measurement results by superimposing result images onto captured images or measurement results.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a stereo three-dimensional measurement system performs three-dimensional measurement by searching for corresponding positions between stereo images, then measurement results can be obtained, but users cannot visually determine whether the reliability index satisfies criteria and cannot identify areas where the index does not satisfy criteria

Engineering Contradiction:

Improvereliability of three-dimensional measurementVSAvoidease of visual verification of measurement reliability

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent applies color coding to visually distinguish between areas with high and low measurement reliability. The display device shows the captured image with overlaid measurement results, using color changes or different display modes to indicate areas where the reliability index satisfies or does not satisfy the criterion. This allows users to quickly identify problematic areas without complex interfaces.

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

The patent introduces a visual intermediary layer between the raw captured image and the measurement data. By superimposing the reliability information onto the captured image display, it creates an intermediate visual representation that bridges the gap between technical measurement data and user-friendly visualization, enabling direct visual verification of reliability criteria.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the system displays only measurement results or captured images, then the display is simple, but users cannot determine whether measurement reliability criteria are satisfied

Engineering Contradiction:

Improvesimplicity of displayVSAvoidloss of reliability information

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The patent merges the captured image display with the measurement results and reliability information into a single integrated display. The display device combines these elements by superimposing measurement data and reliability indicators onto the captured image, creating a unified visual output that maintains simplicity while preserving all necessary information including reliability criteria satisfaction status.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

This image processing system is provided with: a measurement part which measures the three-dimensional shape of a target object based on a captured image obtained by capturing an image of the target object; a reliability calculation part which calculates, for each area, an index that indicates the reliability in the measurement of the three-dimensional shape; a reliability evaluation part which evaluates, for each area, whether the calculated index satisfies a predetermined criterion; and a display part which simultaneously or selectively displays the measurement result of the three-dimensional shape and a result image that shows the area that does not satisfy the criterion in the captured image.
