Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing position searching methods using electronic maps face high costs and low correlation issues when associating images with geographical positions, as user-uploaded or web-sourced images are often irrelevant and require manual review.
Innovation Solution
A method and apparatus that receive a keyword, search an electronic map to obtain the geographical position, acquire panoramic images within a predetermined area, calculate coordinates based on position-related information, and generate an image centered on these coordinates from the panoramic images, enhancing image correlation and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If user-uploaded or web-sourced images are used for position searching, then the quantity of images is increased, but the correlation between images and searching objects deteriorates
Solution Approach 1:
The patent introduces panoramic images as an intermediary resource that bridges the gap between user-uploaded images and searching objects. These panoramic images serve as a structured, pre-organized database that automatically correlates with geographical positions, eliminating the need for manual review while ensuring high relevance to searching objects.
Solution Approach 2:
The patent replaces the mechanical system of manual image review and association with an automated computational system. By using coordinate calculation algorithms and geographical position data, the system automatically matches images with searching objects, substituting human labor with automated processing that maintains high correlation.
2Reliability
If manual reviewing is used to associate images to correct positions, then the correlation between images and positions is improved, but the cost and time consumption increase
Solution Approach 1:
The patent enables the system to serve itself by automatically calculating coordinates and associating images with positions without human intervention. The system uses automated algorithms to process panoramic images, calculate their coordinates, and match them with searching objects, making the entire association process self-service and eliminating manual review.
Solution Approach 2:
The patent changes the parameter of image association from manual categorical judgment to automated coordinate-based matching. By transforming the association criterion into a quantifiable parameter (coordinates), the system enables automated processing that maintains high correlation while dramatically reducing time consumption and cost.
3Measurement precision
If manual reviewing is used to associate images to correct positions, then the accuracy of image association is improved, but the productivity of the system deteriorates
Solution Approach 1:
The patent replaces the mechanical process of manual image review with an automated computational system that calculates coordinates and associates images programmatically. This substitution maintains measurement precision through algorithmic accuracy while dramatically improving productivity by processing multiple images simultaneously without human intervention.
Solution Approach 2:
The patent uses panoramic images as standardized copies that can be systematically processed and associated with multiple searching objects. By creating a standardized image database with known coordinates, the system can efficiently match and associate these image copies with various searching objects, maintaining accuracy while scaling productivity.
