Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In projection mapping, it is challenging to visually recognize the contour of a stereoscopic projection target object in captured images, making it difficult to accurately set the position, shape, and size of the projection image.

Innovation Solution

A system that displays a captured image of a projection target object with its contour indicated by a line, allowing users to superimpose a content image and adjust its position, shape, and size based on user input.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a captured image is displayed on a display device for setting the projection image, then the user can perform operation for setting the position and size, but it is difficult to visually recognize the contour of the projection target object

Engineering Contradiction:

Improvesetting operationVSAvoidcontour recognition

Core Design Contradiction:

Ease of operationVSDifficulty of detecting and measuring

Solution Approach 1:

The patent applies color changes by displaying the captured image in grayscale and highlighting the contour of the projection target object in color (e.g., red or yellow). This allows the contour to stand out against the grayscale background, enabling users to easily recognize and detect the object boundary while performing setting operations on the display device.

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

The patent introduces a guide image as an intermediary element that is superimposed on the captured image. This guide image contains visual cues such as a frame indicating the projection area and arrows showing the direction to move the projection image, facilitating both contour recognition and setting operations simultaneously.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Device complexity

If the captured image is used directly for projection mapping, then the process is simple, but the position and size of the projection image cannot be set accurately

Engineering Contradiction:

Improveprocessing processVSAvoidposition and size setting precision

Core Design Contradiction:

Device complexityVSManufacturing precision

Solution Approach 1:

The patent applies preliminary action by first displaying the captured image in grayscale to allow users to easily identify the projection target object contour, then switching to a color-highlighted display with guide images before the actual setting operation. This preliminary visualization step ensures accurate position and size setting while maintaining a relatively simple overall process.

Inventive Principle:

Principle #10Preliminary action

AI summary

There is provided a recording medium recording a program, the program causing a computer to execute displaying, based on a captured image obtained by capturing an image of a first object, a first image in which a contour of the first object is indicated by a line, displaying an editing image in which a content image indicating content is superimposed on at least a part of the first image, receiving input for changing the at least one of a position, a shape, and a size of the content image in the editing image, and changing at least one of the position, the shape, and the size of the content image based on the input for changing.
