Solution Overview

Problem

Current methods for collecting and processing point of interest (POI) data in electronic maps are inefficient, requiring professional teams and taking a long time due to the need for manual data collection, processing, and transfer, which limits the accuracy and speed of updating POIs.

Innovation Solution

A method and system that utilize a terminal to acquire images and determine if objects within those images are already tagged on an electronic map, allowing for quick recognition and tagging of new POIs by searching historical images associated with the capturing position, thereby improving data processing efficiency and accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If professional teams manually collect and process POI data, then data accuracy is improved, but processing time and cost increase significantly

Engineering Contradiction:
ImprovePOI data accuracyVSAvoiddata collection and processing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical data collection processes with automated image recognition technology. Mobile terminals capture images of POIs, and server-side recognition systems automatically identify and extract POI information from these images, eliminating the need for professional teams to manually collect and process data while maintaining high accuracy

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent uses image copying as an intermediary - instead of directly collecting structured POI data through manual methods, the system captures visual copies (images) of POIs using mobile terminals, then automatically converts these image copies into structured data through recognition algorithms, significantly reducing processing time

Inventive Principle:
Principle #26Copying

2Reliability

If professional teams manually process POI data, then data quality is improved, but labor cost and operational complexity increase

Engineering Contradiction:
ImprovePOI data qualityVSAvoiddata collection system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent enables the system to serve itself by automatically performing data collection, recognition, and processing tasks. Mobile terminals automatically capture images, and the server automatically recognizes and processes POI information without requiring professional teams, thereby maintaining data quality while reducing operational complexity

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent creates a universal system where mobile terminals can serve multiple functions - acting as both data collection devices and image capture devices. The server-side system provides universal processing capabilities that handle various types of POI data through a single automated recognition pipeline, reducing the need for specialized manual processing procedures

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Measurement precision

If traditional manual methods are used for POI collection, then data verification is thorough, but processing speed decreases

Engineering Contradiction:
ImprovePOI information accuracyVSAvoidPOI acquisition efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent enables continuous automated processing of POI data through image recognition. Multiple mobile terminals can continuously capture images of POIs, and the server continuously processes these images without interruption, maintaining thorough verification through automated recognition algorithms while achieving high-speed continuous data acquisition

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The patent performs preliminary image capture and transmission before full processing. Mobile terminals pre-capture images and transmit them to the server, which then performs recognition and verification in advance, enabling rapid POI acquisition by having data ready before it is actually needed for map updates

Inventive Principle:
Principle #10Preliminary action

AI summary

The present disclosure provides a method, a device and a system for processing image tagging information. The method includes the following. A captured image and a capturing position are acquired from a terminal (101; 201). Object recognition is applied to the captured image to determine a first object presented by the captured image (102; 202). A first target image presenting the first object is searched for among one or more historical images associated with the capturing position (103; 205). When the first target image is searched for, it is determined that the first object is duplicated with tagging information of an electronic map (104; 209). When the first target image is not searched for, a corresponding position of the first object on the electronic map is tagged (105; 210).
