Rail Vehicle Image Recognition Map Update
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Creating and updating travel map information for vehicles traveling along rail tracks is time-consuming and labor-intensive, especially when changes occur, as it requires associating extensive position information with basic map information.
Innovation Solution
A vehicle equipped with a travel controller that performs image recognition to determine rail track shapes and control travel portions, an information obtaining portion to collect position information and order, and memory to store this information, allowing the vehicle to travel without complete travel map information and simplify the association process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complete travel map information is prepared in advance by associating position information with basic map information, then the vehicle can travel along the rail track, but the work required to create and update the travel map information takes a substantial amount of time and efforts
Solution Approach 1:
The vehicle performs image recognition and collects position information during its normal travel along the rail track. The travel controller automatically captures images of the rail track, identifies其特征, and associates the position information with basic map information in real-time, eliminating the need for time-consuming preliminary manual preparation of complete travel map information.
Solution Approach 2:
The vehicle's travel controller autonomously performs image recognition, extracts rail track shape information, and updates the travel map information using its own imaging device and position information reader during normal operation. This self-service mechanism eliminates the need for external manual intervention in creating and updating travel map information.
2Reliability
If travel map information is prepared in advance with complete position information association, then the vehicle can navigate accurately, but the system lacks flexibility when changes are made to the travel paths
Solution Approach 1:
The travel map information is dynamically updated during the vehicle's operation. When the vehicle encounters changes in the rail track or travel path, the image recognition system automatically detects these changes and updates the travel map information in real-time, making the system adaptable to path changes without requiring complete re-preparation of travel map information.
Solution Approach 2:
The vehicle continuously captures images and position information during travel, compares them with the stored basic map information, and automatically updates the travel map information based on this feedback. This closed-loop feedback mechanism ensures the system maintains navigation accuracy while adapting to changes in the travel path.
3Ease of manufacture
If the vehicle travels without complete travel map information using image recognition, then the work to create and update travel map information is simplified, but the vehicle needs to determine rail track shapes during travel
Solution Approach 1:
The manual mechanical process of preparing and updating travel map information is replaced by an automated optical system. The imaging device captures images of the rail track, and the image recognition algorithm automatically extracts shape information, substituting the complex manual work with automated optical-mechanical processing.
Solution Approach 2:
The image recognition algorithm acts as an intermediary between the imaging device and the travel controller. It processes the captured images, extracts rail track shape information, and provides this information to the travel controller, simplifying the overall system architecture while enabling automatic travel map creation and updates.
