LiDAR Usage Map Layer for Mobile Device Localization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of platforms to organize and manage LiDAR usage data from mobile devices for improved localization and navigation, especially in environments where satellite-based positioning is unavailable, such as indoors, where LiDAR sensors provide more privacy-sensitive and efficient localization.
Innovation Solution
A system that determines LiDAR usage data from mobile devices and generates a map layer in a geographic database to indicate locations where LiDAR devices have been used, enabling better understanding, optimization, and utilization of this data for various location-based use cases, including geofence-driven transitions between localization technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If LiDAR sensors are used for localization in indoor environments, then localization precision and privacy protection are improved, but there is no platform to organize and manage the usage data, leading to loss of information and reduced productivity
Solution Approach 1:
The patent introduces a mapping service provider as an intermediary platform that collects, organizes, and manages LiDAR usage data from multiple mobile devices. This intermediary system processes raw LiDAR scans and transforms them into structured location signatures and usage patterns, resolving the information loss problem while maintaining localization precision benefits
Solution Approach 2:
The patent creates a universal platform that handles multiple functions: collecting LiDAR data from various devices, organizing usage patterns, generating location signatures, and providing navigation services. This multi-functional system addresses the lack of comprehensive data management while supporting diverse localization needs
2Quantity of substance
If LiDAR scans are collected from multiple mobile devices, then data quantity and coverage are improved, but without a management platform, data quality and usability deteriorate
Solution Approach 1:
The patent implements feedback mechanisms where the mapping service provider analyzes collected LiDAR usage data, identifies quality patterns, and uses this information to improve data collection strategies. The system continuously refines its understanding of effective LiDAR usage based on accumulated data, enhancing both quantity and quality over time
Solution Approach 2:
The patent transforms raw LiDAR scan data into processed location signatures by changing the data parameters and representation format. This transformation process filters out noise and irrelevant information while preserving essential localization features, thereby improving data quality from the accumulated quantity

AI summary
An approach is provided for generating and leveraging map layer(s) representing information associated with Light Detection and Ranging (LiDAR) usage on mobile devices. The approach, for instance, involves determining LiDAR usage data generated by one or more mobile devices. The approach also involves generating a map layer of a geographic database based on the LiDAR usage data. The map layer indicates one or more locations where a LiDAR device was used by the one or more mobile devices based on the LiDAR usage data. The approach further involves providing the map layer as an output.
