Mobile Device Building Identification via Image Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation services are limited in identifying buildings or places a user is looking at, as they primarily rely on known destination names and lack the ability to provide information about visible structures.
Innovation Solution
A method and system that links regional information acquired through a personal device with a location-based service, allowing a mobile device to capture images, extract building information, calculate their location, and display relevant details, using a server to provide additional information based on location and image data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If navigation service uses traditional search function with known destination names, then the service can provide basic navigation information, but the user cannot identify buildings or places they are currently looking at
Solution Approach 1:
The patent introduces an intermediary mechanism that captures images of visible buildings and uses image recognition technology to identify them. The system acts as a mediator between the user's visual perception and the navigation service, converting visual information into actionable location data that triggers relevant information display.
Solution Approach 2:
The patent replaces the traditional mechanical search approach (typing known destination names) with an automated image recognition system. Instead of requiring users to manually input destination information, the system uses computer vision algorithms to automatically identify buildings from captured images, substituting manual search mechanisms with automated visual processing.
2Loss of time
If the mobile device processes image extraction and location calculation locally, then the response time is reduced, but the device complexity increases
Solution Approach 1:
The patent segments the information processing task into two parts: local image capture and preliminary processing done by the mobile device, and complex location calculation and information retrieval done by the server. This segmentation allows the device to perform simple image extraction locally while offloading computationally intensive tasks to the server, reducing both device complexity and response time.
Solution Approach 2:
The server acts as an intermediary that receives image data from the mobile device, performs complex location calculation and building identification, then returns relevant information to the user. This intermediary approach allows the mobile device to remain relatively simple while still achieving fast response times through server-assisted processing.
Data Source
AI summary
A mobile device and a server are provided. The mobile device displays relevant information extracted based on location information and additional information. Accordingly, by linking regional information acquired through a personal device with a location based service, the user is provided with useful contents effectively and further is provided with a new experience.
