Map Imagery Update System Using User Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Images of geographical locations provided in map data may be outdated or inaccurate due to changes in objects over time, leading to incorrect information for users.
Innovation Solution
A computer-implemented method and system that allows users to provide status information about objects in images, determining if the images need updating based on this information, and receiving and integrating updated images from various sources, such as vehicle-mounted cameras or business owners, to maintain accurate map data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If map imagery is captured and stored for later provision to users, then map data can be provided upon request, but the imagery may become outdated or inaccurate due to changes in objects at the location over time
Solution Approach 1:
The system performs preliminary actions by capturing images in advance and storing them for later provision. However, it supplements this with preliminary detection of changes through user feedback mechanisms, allowing the system to proactively identify when updates are needed rather than waiting for users to report inaccuracies.
Solution Approach 2:
The system implements a feedback mechanism where users can report changes or inaccuracies in the displayed imagery. This feedback loop allows the system to continuously improve the accuracy of map data by incorporating real-world observations from users, resolving the contradiction between providing timely map data and maintaining its accuracy.
2Reliability
If updated imagery is obtained and integrated into map data, then the accuracy and currency of map information is improved, but the complexity of the system increases
Solution Approach 1:
The system uses an intermediary approach by leveraging user reports as intermediaries between the actual state of locations and the map database. Instead of implementing complex automated detection systems, the patent uses user feedback as a mediator to identify changes, simplifying the overall system architecture while maintaining accuracy.
Solution Approach 2:
The system enables self-service updating by allowing users to independently report changes they observe at locations. This distributes the workload of detecting changes across many users rather than requiring a centralized complex detection system, reducing system complexity while improving imagery currency.
Data Source
AI summary
A system and method are provided for updating imagery associated with map data. A request for map data is received, and a first image of a geographical location corresponding to the map data is provided in response to the request. Information relating to a status of an object in the first image is received, and it is determined whether the first image is to be updated based at least on the received information. If it is determined that the first image is to be updated, an updated image is received and used to update the first image.
