Scene Analysis for Unique Robot Positioning With Navigation Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Robotic navigation systems face challenges in determining unique positions within a scene or venue, as multiple positions can have similar angles to navigation elements, leading to ambiguity and potential loss of location if the robot moves from a unique to a non-unique position.
Innovation Solution
A method and system that analyze a scene or venue by providing image data from an imaging element, determining visible navigation elements, calculating angles to these elements, identifying groups of positions where angles vary by no more than 10 degrees, and outputting information to distinguish unique from non-unique positions, which may involve adding, removing, or displacing navigation elements to ensure unique positioning.

1Measurement precision
If navigation elements are provided in the room to assist robot navigation, then the robot can determine its position, but multiple positions can have similar angles to navigation elements leading to position ambiguity
Solution Approach 1:
The system performs feedback analysis by comparing the actual angles measured from the robot's position to the angles that would be observed from candidate positions in the database. This feedback mechanism allows the system to identify and eliminate ambiguous positions, ensuring reliable and unique position determination even in environments where multiple positions might otherwise appear similar
Solution Approach 2:
The system pre-calculates and stores angle information for multiple candidate positions in a database before the robot needs to determine its position. This preliminary action creates a reference framework that enables rapid and accurate position identification by comparing real-time measurements against pre-computed angle data, preventing position ambiguity before it occurs

AI summary
In a method or system in which an imaging element views navigation elements for e.g. navigation, the navigating elements may not be positioned optimally. Positions may exist in which the same angles exist from the imaging element to the same or similar navigating elements, whereby the positions are not unique. Navigation elements may then be repositioned, added or removed to make the positions unique.
