Marker-Based Position Identification for Target Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for informing a user of a target position in a workspace do not account for the positional relation between the user and the captured image, requiring the target position to be within the imaging range.
Innovation Solution
An information processing device that acquires map data of markers in a space, identifies the user's position based on captured image data, and informs the user of the target position relative to the identified position, using first acquisition means for map data, second acquisition means for image data, identification means, and informing means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the target position is informed based on captured image data, then the user can be informed of the target position, but the target position must be within the imaging range
Solution Approach 1:
The patent introduces markers as intermediary objects disposed at known positions throughout the workspace. These markers serve as reference points that can be captured by the imaging device to establish the user's position. By using markers as mediators between the imaging device and the target position, the system can inform users of target positions even when those targets are outside the current imaging range, as long as markers are visible and the marker database contains information about the target position relative to the captured markers.
2Adaptability or versatility
If markers are disposed throughout the space to enable position identification, then the target position can be informed even when not in imaging range, but the system complexity increases
Solution Approach 1:
The patent creates a virtual copy or digital representation of the physical workspace by establishing a database that maps marker positions to their corresponding real-world locations. This digital twin approach allows the system to provide position information without requiring physical infrastructure beyond the markers themselves. The database acts as a copy of the spatial relationships, enabling the system to inform users of target positions computationally rather than requiring direct visual or physical access to all locations.
Data Source
AI summary
An acquisition unit acquires a photographed image data which is photographed by a user at a first position in a space. The photographed image includes at least any of the multiple markers. An identification unit identifies the first position, on which user have photographed an image, based on the markers included in the photographed image. An informing unit identifies second position relative to the first position identified by the identification unit, and informs the user of the second position relative to the first position.
