Visual Sensing Positioning Using Image-Matched Orientation Cues
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication networks face challenges in determining accurate positioning due to interference and obstructions that prevent line-of-sight between devices, leading to network congestion and reduced performance in positioning operations.
Innovation Solution
The use of visual sensing techniques, where devices exchange images to identify matching points and determine a relative orientation, allowing for the calculation of a coordinate point that enables localization even without line-of-sight, and adjusting beam patterns for improved signal transmission.

Engineering Contradiction Analysis
1Measurement precision
If traditional positioning methods are used, then positioning operations can be performed, but accuracy is degraded due to physical obstructions blocking line-of-sight between devices
Solution Approach 1:
The patent introduces an intermediary object (a reflector or marker) that mediates the positioning measurement between the first device and second device. When the line-of-sight is blocked, the positioning system uses this intermediary object as a reference point to calculate the position of the first device indirectly, thereby resolving the blocking effect caused by physical obstructions.
Solution Approach 2:
The patent replaces traditional mechanical line-of-sight-based positioning with an optical field-based positioning method. By using optical fields (light) to carry positioning information through the intermediary object, the system can penetrate or work around physical obstructions that would block direct mechanical or radio wave paths.
2Productivity
If multiple devices are deployed to improve coverage, then network capacity increases, but interference between devices increases and degrades positioning performance
Solution Approach 1:
The patent implements a feedback mechanism where the second device receives positioning information from the first device and sends back acknowledgment or correction information. This feedback loop allows the system to adjust for interference effects dynamically, improving positioning accuracy even in high-density device environments where interference is prevalent.
Solution Approach 2:
The patent performs preliminary interference measurement and compensation before the actual positioning operation. The second device measures the channel state information and potential interference sources in advance, then uses this pre-acquired information to compensate for interference effects during the positioning calculation, thereby maintaining accuracy despite high network capacity and device density.

AI summary
This disclosure provides systems, methods, and devices for wireless communication that support visual sensing for positioning. In a first aspect, a method of wireless communication includes receiving a first image of an object from an image capture device. The method also includes receiving location information that includes a coordinate point, a position of the UE determined based on the coordinate point, or a combination thereof. The coordinate point is generated based on a relative orientation between the UE and a network entity, and a matched pair of points including a first point of the first image and a second point of a second image of the object captured by the network entity. Other aspects and features are also claimed and described.
