Mobile Terminal Pose Data Detection for Indoor Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional positioning technologies face limitations in accurately identifying and communicating with nearby mobile terminals, particularly indoors, due to errors in location measurement and requiring intentional actions from both terminals for recognition.
Innovation Solution
A method where a mobile terminal detects and communicates with a synchronized terminal by matching pose data, including location direction and inclination, without requiring intentional action from the synchronized terminal, using a detection server to identify terminals within a predetermined radius that match the reference pose data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional positioning technology (GPS or base station signal) is used to locate mobile terminals, then location measurement can be achieved, but the accuracy is insufficient (error range of several meters) to distinguish nearby terminals
Solution Approach 1:
The patent transitions from two-dimensional GPS coordinates to three-dimensional pose data by incorporating inclination angle and location direction. This dimensional expansion enables precise differentiation of terminals in close proximity by considering their spatial orientation, not just their position coordinates.
Solution Approach 2:
The system changes the parameters used for terminal identification from basic location coordinates to comprehensive pose parameters including inclination angle and location direction. This parameter transformation allows the system to achieve fine-grained discrimination between nearby terminals that cannot be distinguished using conventional positioning alone.
2Reliability
If conventional mutual recognition method is used where both terminals must perform intentional actions, then terminal identification can be achieved, but the operation becomes complex and requires participation from both parties
Solution Approach 1:
The detecting terminal independently performs terminal identification by analyzing pose data of surrounding terminals without requiring the target terminal to take any action. The system uses the target terminal's own pose characteristics (inclination, direction) as identification markers, allowing unilateral detection and eliminating the need for mutual recognition protocols.
Solution Approach 2:
The patent introduces pose data as an intermediary element that enables terminal identification. Instead of requiring direct communication or mutual action between terminals, the system uses the physical pose characteristics as a mediator that the detecting terminal can analyze to identify and specify the target terminal unilaterally.
3Measurement precision
If GPS is used for location measurement, then location can be obtained, but it cannot be used indoors
Solution Approach 1:
The system uses pose data (inclination angle and location direction) as a universal identification mechanism that works both indoors and outdoors. This multi-functional approach allows the same identification protocol to operate in environments where GPS is unavailable (indoors) as well as where it is available (outdoors), making the system adaptable to various settings.
