Navigation System Image-Based Boarding Guide for Trains
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional navigation systems fail to accurately guide users in identifying the correct ticket gate, route, and platform when boarding an electric train, as they rely solely on station name signboards and do not provide information on the user's current route or platform alignment.
Innovation Solution
A navigation system comprising a terminal apparatus and a navigation server that processes images of boarding guide display items, such as station name signboards or route maps, to identify the current station, route, and traveling direction, and generates guide information including relevant station names and platform information, ensuring accurate alignment with the user's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If only station name signboard identification is used, then the system is simple to operate, but it cannot provide comprehensive route and platform guidance information
Solution Approach 1:
The guidance information is segmented into multiple components: current station identification, route determination, traveling direction, and platform alignment. Each component is processed and presented separately to provide comprehensive guidance while maintaining system simplicity
Solution Approach 2:
The navigation system performs multiple functions through a single integrated process: it identifies the current station, determines the user's route, establishes traveling direction, and provides platform alignment information, replacing multiple separate systems with one universal solution
2Device complexity
If only station name signboard identification is used, then the device complexity is low, but it cannot determine user's current route and platform alignment
Solution Approach 1:
The system performs preliminary actions by first identifying the current station and determining the user's route before providing platform alignment information. This sequential approach ensures that all necessary information is prepared in advance, reducing the need for complex real-time processing
Solution Approach 2:
The navigation server acts as an intermediary that receives the photographed image from the terminal apparatus, processes it to extract multiple pieces of information (station name, route, direction, platform), and returns comprehensive guidance information, simplifying the overall system architecture
3Ease of operation
If conventional navigation systems are used, then the system is easy to operate, but users cannot identify the tie-up between current position and route search result
Solution Approach 1:
The system provides feedback by comparing the user's current position (identified through photographed image analysis) with the route search result. This feedback mechanism confirms whether the user is on the correct route and provides platform alignment information, ensuring accurate position identification
Solution Approach 2:
The system replaces manual position verification with automated image recognition and analysis. The terminal apparatus captures images of boarding guide display items, and the navigation server automatically extracts position information, eliminating the need for manual position checking

AI summary
A navigation device presenting guide information based on a photographed image of a boarding guide display item, such as a station name signboard, a roll sign, or a route map, that can be photographed in a station yard. The device acquires a photographed image of a boarding guide display item by controlling the photographing unit, identifies display content from the photographed image of the boarding guide display item of a transportation device acquired and specifying a route, station name, and traveling direction of a current position based on the identified display content and traffic network data stored in the storage unit, extracts station names present in the traveling direction from the traffic network data based on the route, station name, and traveling direction of the current position, and generates guide information including at least part of the extracted station names, and outputs at least part of the generated guide information.
