2D Barcode Location Sharing with Street-View Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for sharing location information, such as business cards and text-based systems, are inefficient and limited in providing street-view and surrounding information, hindering the development of comprehensive location-based applications.
Innovation Solution
A method and system that generates and scans two-dimensional (2D) barcodes containing street-view image information and corresponding location information, allowing for efficient retrieval and sharing of location details through the combination of immersive street-view images and location data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If text information (business cards, envelopes) is used to share location information, then the method is simple to implement, but the information sharing efficiency is low and street-view/surrounding information cannot be provided
Solution Approach 1:
The patent combines multiple types of information (location coordinates, street-view images, surrounding information) into a single 2D barcode. This merging allows comprehensive location information to be encoded in one compact format that can be scanned and decoded efficiently, resolving the contradiction between information completeness and sharing efficiency
Solution Approach 2:
The patent transitions from traditional one-dimensional text-based location sharing to two-dimensional barcode encoding. This dimensional change enables significantly higher information density, allowing street-view images and detailed location data to be embedded in a compact visual format that maintains high sharing efficiency while preventing information loss
2Loss of information
If two-dimensional map locating applications are used, then location information can be obtained, but users cannot understand street-view and surrounding information of specific locations
Solution Approach 1:
The patent performs preliminary encoding of street-view images and location information into 2D barcodes before the user needs the information. The barcode is generated in advance with all necessary data embedded, so when scanned, the information is immediately available without requiring complex real-time processing or additional device complexity
Solution Approach 2:
The patent creates a compact visual copy (2D barcode) that contains encoded representations of location data and street-view information. This copy serves as a portable, scannable alternative to complex map applications, providing full information access without requiring the user to interact with complex mapping systems
3Loss of information
If comprehensive location information including street-view images is provided, then the information completeness is improved, but the information storage and retrieval complexity increases
Solution Approach 1:
The patent changes the parameter of information representation from human-readable text to machine-readable 2D barcode format. This parameter change enables comprehensive location information including images to be stored in a compact, structured format that can be rapidly retrieved through optical scanning, reducing the effective complexity of storage and retrieval operations

AI summary
A method for obtaining location information is provided. The method includes obtaining street-view image information corresponding to location information and storing correspondingly the street-view image information and the corresponding location information. The method also includes generating a two-dimensional (2D) bar code containing at least one of the street-view image information and the corresponding location information. Further, the method includes scanning the 2D bar code to obtain the at least one of the street-view image information and the location information, where searching the location information based on the street-view image information when the scanning of the 2D bar code obtains the street-view image information and searching the street-view image information based on the location information when the scanning of the 2D bar code obtains the location information.
