Solution Overview

Problem

Existing projection mapping technologies require repeated projection and capturing of pattern images, leading to a lengthy process from measurement start to projection image setting due to the inability to perform other processing during measurement.

Innovation Solution

A system that executes first processing to acquire measurement information from captured images of pattern images projected onto a projection region, while simultaneously performing second processing concerning the projection image, thereby reducing overall processing time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If repeated projection and capturing of pattern images is performed to achieve accurate measurement information, then measurement precision is improved, but loss of time increases

Engineering Contradiction:
Improvemeasurement information accuracyVSAvoidprocessing time from measurement start to projection image setting
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs first processing (acquiring measurement information from captured images) and second processing (adjusting the projection image) simultaneously in an overlapping time period. This continuous execution of multiple useful actions reduces the total time from measurement start to projection image setting completion, while maintaining measurement precision through the sequential pattern image projection method

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The system starts the second processing (projection image adjustment) before the first processing (measurement information acquisition) is completely finished. By initiating the adjustment process preliminarily using available measurement data, the system reduces overall processing time while completing accurate measurements through the remaining pattern image projections

Inventive Principle:
Principle #10Preliminary action

2Measurement precision

If multiple pattern images are projected and captured sequentially to obtain measurement information, then measurement precision is improved, but productivity decreases

Engineering Contradiction:
Improvemeasurement information accuracyVSAvoidprocessing efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent enables continuous productive work by executing first processing and second processing simultaneously. While multiple pattern images are being projected and captured for accurate measurement, the system concurrently performs projection image adjustment operations, thereby maintaining high productivity without compromising measurement precision

Inventive Principle:
Principle #20Continuity of useful action
