Navigation System Using Logo Feature Codes for Manual Input Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional GPS navigation systems require manual input of text addresses, which is unsafe and inconvenient for drivers.
Innovation Solution
A navigation system that uses an image capturing device, processing device, and positioning device to calculate a feature code from logos or barcodes, retrieving address information from a database to determine routes without manual input, employing algorithms like SIFT for image processing and utilizing one- or two-dimensional barcodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual text input is used for destination input, then navigation functionality is achieved, but driving safety deteriorates and operation convenience worsens
Solution Approach 1:
The patent replaces manual text input operations with automatic image recognition and processing. The system captures images of destinations using an image capturing device, automatically extracts location information through processing, and inputs it to the navigation system, eliminating the need for manual keyboard or touchscreen input while driving.
Solution Approach 2:
The system performs self-service by automatically capturing destination images, processing them to extract location information, and inputting navigation data without requiring driver intervention. The image processing and information extraction are automated functions that serve the navigation purpose independently.
2Reliability
If electronic maps are used for navigation, then route calculation is enabled, but navigation reliability deteriorates when maps are outdated
Solution Approach 1:
The patent introduces image recognition and feature code extraction as an intermediary layer between the destination and navigation system. By capturing images of destinations and extracting location information through feature codes or barcodes, the system obtains real-time location data that supplements or updates traditional electronic map information, ensuring navigation accuracy even when maps are outdated.
3Ease of operation
If image recognition is implemented, then manual input is eliminated, but processing complexity increases
Solution Approach 1:
The patent segments the image processing task into distinct functional modules: image capturing, feature detection, feature code extraction, and location information retrieval. This modular segmentation simplifies the overall processing complexity by breaking down the complex image recognition task into manageable, specialized components that can be processed independently.
