Beacon Mesh Localization for Building Data Acquisition Sites
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods struggle to accurately and efficiently determine the acquisition locations of data within buildings without physical travel, and using floor plans is cumbersome and difficult to maintain and scale.
Innovation Solution
Utilize a mesh network of beacon transmitter devices to determine the positions of data acquisition locations within buildings, using wireless transmissions to triangulate and geometrically calculate positions, without requiring depth sensors or distance-measuring devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If floor plans are used to represent building interiors, then layout information can be provided to users, but the system becomes difficult to construct, maintain, and scale
Solution Approach 1:
The patent replaces manual floor plan construction and maintenance with automated image processing and computer vision algorithms. The system automatically generates floor plans from captured images, eliminating the need for manual drafting and updating processes.
Solution Approach 2:
The system enables self-service by automatically capturing, processing, and updating building interior representations without requiring manual intervention. The automated navigation system also allows users to independently explore and interact with the digital twin of the building.
2Measurement precision
If physical travel to buildings is required to acquire interior information, then accurate building data can be obtained, but time and resource consumption increase
Solution Approach 1:
The patent creates a digital copy or digital twin of the building interior by capturing images and generating a virtual representation. This digital copy preserves accurate spatial and visual information without requiring physical presence in the building.
Solution Approach 2:
The system performs preliminary action by pre-capturing and processing building interior images to create an up-to-date digital representation before users need the information. This eliminates the need for on-demand physical visits for data collection.
3Ease of operation
If traditional navigation methods are used in buildings, then users can move through spaces, but automated navigation and vehicle guidance are limited
Solution Approach 1:
The patent implements a universal navigation system that serves multiple functions: it provides wayfinding for pedestrians, guides autonomous vehicles, and supports various modes of building interaction through a single integrated digital representation and positioning infrastructure.

AI summary
Techniques are described for using computing devices to perform automated operations for using wireless transmitter devices (e.g., beacon devices) at a building for determining the acquisition locations of images or other data acquired at the building, and for subsequently using the acquired data and determined acquisition location information in one or more further automated manners. Images to be analyzed may include panorama images acquired at acquisition locations in an interior of a multi-room building, and the determined acquisition location information may include a location on a building floor plan and optionally orientation direction—the acquisition location determination may further be performed without having or using information from any distance-measuring devices about distances from an image's acquisition location to objects in the surrounding building. The acquisition location information may be used in various automated manners, including for controlling navigation of devices (e.g., autonomous vehicles).
