Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems inaccurately determine vehicle passage based solely on stored road width data, failing to account for actual road conditions and obstructions.
Innovation Solution
An information processing device that acquires satellite images, detects obstructions using machine learning, and calculates road width considering actual obstructions and oncoming vehicles to determine passage feasibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If road width data from database is used to determine vehicle passage, then the determination process is simple and fast, but the accuracy of passage determination is insufficient due to ignoring actual road conditions
Solution Approach 1:
The system performs preliminary actions by acquiring satellite images and detecting obstructions before the vehicle reaches the travel path. This allows the road width calculation to be based on actual current conditions rather than relying solely on database information, thereby improving passage determination accuracy while maintaining efficient real-time performance
Solution Approach 2:
The patent introduces satellite images as an intermediary to bridge the gap between database road width data and actual road conditions. The satellite images provide real-time visual information about obstructions, which serves as a mediator to improve the accuracy of passage determination without requiring direct complex sensing of the road surface
2Measurement precision
If satellite image acquisition and obstruction detection are added to improve passage determination accuracy, then passage determination accuracy is improved, but the device complexity and processing time increase
Solution Approach 1:
The system performs preliminary action by acquiring satellite images and detecting obstructions in advance before the vehicle reaches the scheduled travel path. This timing strategy allows sufficient time for image processing and obstruction detection without delaying the vehicle's travel, thereby improving accuracy while minimizing time loss
Solution Approach 2:
The patent replaces mechanical or direct physical sensing systems with satellite-based remote sensing and image processing. This substitution allows for non-contact, large-area observation of road conditions, reducing the complexity and time required for on-ground sensing while maintaining high accuracy in obstruction detection

AI summary
A information processing device includes: a processor, wherein the processor is configured to: acquire a satellite image of a scheduled travel path, among satellite images captured by an artificial satellite; detect, from the acquired satellite image, an obstruction that a host vehicle should avoid on the scheduled travel path; and calculate a road width for which passage of the host vehicle is possible on the scheduled travel path, in consideration of the detected obstruction.
