Relative Location Detection Using Image Perspective Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumer-based GPS systems are not accurate enough to enable precise location detection of two users in crowded areas, as they often indicate users are at the same location when they are still far apart.
Innovation Solution
A system and method using image perspective analysis on electronic devices, which includes a camera module, sensors for motion characteristics, and a processor to determine the relative location of a target device by comparing photographic data, allowing for higher accuracy in location detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS-based location detection is used, then location detection capability is provided, but measurement precision is insufficient in crowded areas
Solution Approach 1:
The patent introduces common visual elements (landmarks, buildings, objects) as intermediaries between two devices to establish relative location. Instead of directly measuring distance between devices, the system uses these environmental intermediaries that both devices can capture in their images, enabling indirect but precise location determination through image comparison
Solution Approach 2:
The patent replaces the GPS satellite-based electromagnetic signal system with a local optical image-based system. By substituting the mechanical/electromagnetic GPS infrastructure with a camera-based visual recognition system, the invention achieves higher precision in crowded areas where GPS signals fail, while keeping device complexity manageable through software processing
2Measurement precision
If image perspective analysis is used to improve location accuracy, then measurement precision increases, but device complexity increases
Solution Approach 1:
The patent creates a visual copy of the environment from each device's perspective through captured images. By comparing these image copies and identifying common elements, the system determines relative location without requiring complex direct measurement instruments, leveraging the copying and comparison of visual information instead
Solution Approach 2:
The patent changes the parameter of location representation from absolute GPS coordinates to relative position based on image perspective analysis. By transforming the location parameter from satellite-based coordinates to camera-based visual field comparison, the system achieves higher precision in local areas while managing complexity through algorithmic processing

AI summary
A system and method of relative location detection on an electronic device using image perspective analysis. The electronic device will consist of a processor module coupled to a camera module. The camera module of an electronic device as well as a target device will be used to capture image(s) of the current surroundings, including common elements, which will then be used to obtain the relative location of the devices in reference to one another.
