Solution Overview

Problem

Current augmented reality techniques only allow for the viewing of objects and do not facilitate easier interaction with real objects, lacking the ability to preview or create textures on real objects effectively.

Innovation Solution

A method that involves acquiring a real-world image, detecting a marker linked to the object, registering a virtual world with the real world, placing a three-dimensional virtual object overlaid on the real object, applying texture to the virtual object, and displaying it from a corresponding viewpoint, using techniques like texture mapping to align and adjust the virtual object to match the real object's shape and position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If current augmented reality techniques are used to display virtual objects, then virtual objects can be overlaid on real-world images, but users cannot preview or create textures on real objects effectively

Engineering Contradiction:

Improvetexture application capabilityVSAvoidinteraction with real objects

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent creates a three-dimensional virtual copy of the real object and applies texture to this virtual copy rather than directly to the real object. This virtual copy serves as an intermediary that can be manipulated, textured, and displayed without affecting the actual physical object, enabling preview and creation functions.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The three-dimensional virtual object acts as an intermediary between the user and the real object. Users interact with the virtual object for preview and creation purposes, while the virtual object serves as a mediator that translates these interactions into appropriate actions on the real object.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Manufacturing precision

If a three-dimensional virtual object is placed and textured to match a real object, then accurate overlay and preview are achieved, but the system complexity increases

Engineering Contradiction:

Improveoverlay accuracyVSAvoidsystem complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The system performs preliminary actions by acquiring images of the real object, extracting its three-dimensional geometry, and creating a virtual model before applying texture. This preparation enables accurate overlay while managing complexity through structured processing steps.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent segments the object into a three-dimensional virtual representation that can be independently processed for geometry and texture application. This segmentation allows the complex task of accurate overlay to be divided into manageable steps: image acquisition, geometry extraction, virtual model creation, and texture application.

Inventive Principle:

Principle #1Segmentation

AI summary

A method and kit for applying texture in augmented reality including the steps of acquiring a real-world image in which a real object and at least a portion of a marker linked to the real object are visible; detecting the marker; registering a virtual world with the real world on the basis of the marker detection; positioning a three-dimensional virtual object in such a way that, in the virtual world, the virtual object is substantially overlaid over the real object in the real world; applying a texture to the three-dimensional virtual object; and displaying at least the texture applied to the three-dimensional virtual object.
