Augmented Reality View Shifting via Pre-Captured Image Database
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality systems are limited in providing space information that is occluded by other facilities or located at a distance from the user's current location, as they rely on real-time camera views and cannot easily access information from invisible or distant spaces.
Innovation Solution
An augmented reality method and system that generates and shifts views based on sensor information from a mobile device, using a database of pre-captured images with location information to provide panoramic views of exterior, interior, aerial, or underground spaces by calculating a view shift location based on travel distance, azimuth, and altitude, allowing intuitive user control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If real-time camera views are used for augmented reality, then the system can provide current visual information, but it cannot access space information that is occluded or located at a distance
Solution Approach 1:
The system pre-captures images at multiple locations and stores them in a database before they are needed. When a user requests augmented reality information, the system retrieves pre-stored images from the database that correspond to the calculated view shift location, rather than attempting to capture images in real-time from occluded or distant spaces.
2Adaptability or versatility
If the system relies on current camera views, then it maintains simplicity in operation, but it cannot provide panoramic views of exterior, interior, aerial, or underground spaces
Solution Approach 1:
The system introduces a database as an intermediary component that stores pre-captured images. The server acts as a mediator that receives control command signals from the mobile device, calculates view shift locations, retrieves appropriate images from the database, and transmits them back to the mobile device, enabling diverse view types without requiring the mobile device itself to have complex capabilities.
Solution Approach 2:
The system extends the viewing capability from a single real-time camera perspective to multiple dimensional views by storing and retrieving images from different spatial dimensions (exterior, interior, aerial, underground) in the database, allowing users to access information from multiple spatial perspectives simultaneously.
3Loss of information
If augmented reality is based on current camera images, then the system operates with simple controls, but it cannot provide information beyond the user's current location
Solution Approach 1:
The system replaces the mechanical limitation of physical camera movement with computational methods. The server calculates view shift locations using sensor information (azimuth, altitude, travel distance) and retrieves corresponding pre-captured images from the database, substituting physical camera relocation with digital image selection and transmission.

AI summary
An augmented reality providing method may include providing space information corresponding to an image acquired from a mobile device as augmented reality, based on the image; calculating a view shift location for shifting a view in the augmented reality under control of the mobile device; extracting an image corresponding to the view shift location from a database that stores an image including location information; and providing the extracted image under control of the mobile device.
