Information Processing Device Position-Based Display Reliability

Solution Overview

Problem

Existing techniques for recognizing markers and displaying associated information fail when markers are obscured or not in appropriate positions, leading to incomplete or unavailable information display.

Innovation Solution

An information processing device and method that acquires images, recognizes objects, and stores associated information along with positional data, enabling information display even when objects are not directly recognizable.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If marker recognition is used to display information, then information can be displayed according to recognized objects, but information cannot be displayed when markers are hidden or not in appropriate positions

Engineering Contradiction:

Improveinformation display reliabilityVSAvoiddisplay adaptability to object position

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system performs preliminary action by storing both image data and coordinate information when objects are successfully recognized. This pre-stored data serves as a backup that can be retrieved and displayed later even when the actual object recognition fails due to obscuration or improper positioning, ensuring continuous information availability.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system creates a copy of the object information by storing image data and coordinate information in the storage unit. This copied data can be retrieved and displayed without requiring the original object to be currently visible or recognizable, thus maintaining display reliability when markers are hidden.

Inventive Principle:

Principle #26Copying

2Measurement precision

If only current object recognition is used for display, then display accuracy is high when objects are visible, but information becomes unavailable when objects are not recognized

Engineering Contradiction:

Improveobject position accuracyVSAvoidinformation availability

Core Design Contradiction:

Measurement precisionVSLoss of information

Solution Approach 1:

The system performs preliminary action by storing both image data and coordinate information when objects are successfully recognized. This pre-stored data serves as a backup that can be retrieved and displayed later even when the actual object recognition fails due to obscuration or improper positioning, ensuring continuous information availability.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system transitions from relying solely on real-time object recognition to utilizing stored coordinate information from a different temporal dimension. By storing and retrieving past recognition data, the system maintains position accuracy information even when current recognition fails, effectively adding a temporal dimension to the display system.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If marker-based information display is implemented, then information can be associated with specific objects, but the system fails when markers detach or are obscured

Engineering Contradiction:

Improveobject-information associationVSAvoiddisplay functionality

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system achieves universality by implementing multiple functions: it can display information based on current object recognition when available, and alternatively retrieve and display previously stored image data and coordinate information when recognition fails. This multi-functional approach ensures display reliability across different scenarios.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system performs preliminary action by storing both image data and coordinate information when objects are successfully recognized. This pre-stored data serves as a backup that can be retrieved and displayed later even when the actual object recognition fails due to obscuration or improper positioning, ensuring continuous information availability.

Inventive Principle:

Principle #10Preliminary action

AI summary

The present invention stores information associated with an object such that the information can be displayed in display mode corresponding to the position of the object, even in a state wherein the object is not recognized. An information processing device 100 includes: an acquisition unit 110 that acquires an image; a recognition unit 120 that recognizes an object on the basis of the image acquired by the acquisition unit 110; and a storing unit 130 that stores, with second information relating to the position of the object, first information corresponding to the object, in the cases where the object is recognized by the recognition unit 120.
