Map-Based Localization and Low-Bandwidth Scene Reconstruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing localization systems for navigation-restricted mobile subsystems, such as vehicles, rely heavily on satellite navigation networks, making them vulnerable to communication restrictions or denial, and observed scene reconstruction requires significant bandwidth, which can be a challenge in limited connectivity scenarios.
Innovation Solution
A localization processing service using an observing subsystem with an image sensor, memory, and processing module to determine location and orientation based on map features, and an observed scene reconstruction service to transmit and reconstruct scenes remotely, enabling localization and scene reconstruction without network communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If satellite navigation networks are used for localization, then positioning accuracy is improved, but vulnerability to communication restrictions increases
Solution Approach 1:
The patent introduces map features as an intermediary between the camera and the localization process. Instead of directly relying on satellite navigation signals, the system captures images, extracts features from them, and matches these features against pre-stored map data to determine position. This intermediary approach allows localization to continue even when satellite communication is restricted or denied.
Solution Approach 2:
The system creates a local copy of the environment by storing map features and rendered map images in a database. This copied representation of the physical environment can be processed locally without requiring real-time satellite communication, enabling the system to determine position by comparing captured images against these pre-stored copies of the environment.
2Loss of information
If observed scenes are transmitted remotely, then scene reconstruction capability is improved, but communication bandwidth requirements increase
Solution Approach 1:
The patent extracts only the essential elements needed for scene reconstruction - specifically, attribute data describing the scene and its objects - rather than transmitting the complete observed image data. This extraction approach maintains the ability to reconstruct scenes remotely while significantly reducing the amount of data that needs to be communicated over bandwidth-limited channels.
Solution Approach 2:
The system performs preliminary processing of the observed scene by extracting and transmitting attribute data before full reconstruction is needed. This preliminary action prepares the essential information in advance, allowing the receiving system to reconstruct the scene efficiently without requiring large bandwidth for real-time transmission of complete image data.
