Dual-View Object Mapping for Wireless Blind-Spot Reflector Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques struggle to determine the optimal placement of reflectors to efficiently eliminate radio blind spots in wireless communication, particularly with millimeter waves, due to challenges in determining the location based on location information and communication status.
Innovation Solution
An information processing apparatus that obtains first and second data indicating objects within specific angles of field relative to base points with sub-threshold communication quality, calculates common locations among these data sets, and outputs these locations for installing reflectors or relay apparatuses to improve communication quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If location information and communication status are used to determine relay machine location, then line-of-sight connection is secured, but it is difficult to remove radio blind spots
Solution Approach 1:
The patent introduces imaging data as an intermediary element to bridge the gap between location information and blind spot removal. By obtaining imaging data from both the base station and the relay machine, and calculating intersection points of detected objects, the system can precisely determine optimal reflector installation locations that address blind spots while maintaining line-of-sight connections.
2Ease of manufacture
If reflector installation location is determined based on conventional methods, then implementation is simplified, but accurate blind spot removal cannot be achieved
Solution Approach 1:
The patent replaces conventional mechanical/location-based methods with an optical measurement approach using imaging data. By capturing images from both base station and relay machine perspectives and calculating the intersection of detected objects, the system achieves precise determination of reflector installation locations that accurately target blind spots.
3Measurement precision
If imaging data from multiple base points is obtained, then blind spot identification accuracy is improved, but data processing complexity increases
Solution Approach 1:
The patent segments the data processing into distinct functional steps: obtaining imaging data from base station and relay machine separately, detecting objects in each image independently, calculating intersection points of common objects, and determining reflector installation locations. This segmentation reduces overall processing complexity while maintaining high accuracy.

AI summary
To output information for removing a radio blind spot in wireless communication, an information processing apparatus (1) includes: an obtaining section (11) that obtains first data and second data, the first data indicating objects included in a first angle of field in which a first base point is set at a location at which quality of communication with a base station is not more than a predetermined threshold, the second data indicating objects included in a second angle of field in which a second base point is set at the base station; a calculation section (12) that calculates one or more locations each indicated by a corresponding one of one or more objects each indicated in common by both the first data and the second data; and an output section (13) that outputs at least one of the one or more locations calculated by the calculation section (12).
