Cross-Platform Point-of-Interest Transfer via Shared Reference Image
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tracking systems face challenges in accurately transferring point-of-interest coordinate locations between different platforms with varying viewing directions, making it difficult to identify and update information across multiple platforms.
Innovation Solution
A method for displaying point-of-interest coordinate locations in perspective images involves providing a shared reference image with a defined coordinate system, correlating the perspective view with the shared reference image to generate a mapping, and indicating the location on the display, which can also automatically re-align the imaging sensor to bring the location within the field of view if necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If point-of-interest information is identified in images from a first platform, then the information can be used to identify the same P.O.I. from another platform, but the different viewing directions of separate platforms complicate the information transfer
Solution Approach 1:
The patent introduces a shared reference image as an intermediary coordinate system that mediates between different platform perspectives. Each platform's perspective image is correlated with the shared reference image, and point-of-interest coordinates are transferred through this common reference frame, enabling accurate cross-platform information transfer despite different viewing directions
Solution Approach 2:
The patent creates a virtual copy of the point-of-interest location by correlating the source platform's perspective image with the shared reference image to extract coordinates, then uses these coordinates to locate and display the same point in the target platform's perspective image, effectively copying the location information across different viewing contexts
2Loss of information
If point-of-interest coordinates are transferred between platforms, then information sharing is enabled, but the transfer must be both compact and precise
Solution Approach 1:
The patent transfers only the essential coordinate information (x, y coordinates in the shared reference image) from one platform to another, creating a compact data representation. This coordinate copying approach maintains precision while minimizing data transfer requirements, as only numerical coordinates need to be transmitted rather than entire image datasets
3Measurement precision
If image correlation is used to map perspective views to reference images, then point-of-interest locations can be accurately derived, but the processing complexity increases
Solution Approach 1:
The patent performs preliminary correlation between each platform's perspective images and the shared reference image to establish mapping relationships in advance. These pre-computed correlations enable rapid coordinate derivation without requiring complex real-time processing during point-of-interest identification, reducing operational processing complexity
Solution Approach 2:
The shared reference image serves as an intermediary that simplifies the mapping process. Instead of directly correlating between different platform perspectives (which would be complex), the system uses the reference image as a common intermediary frame, making the correlation process more systematic and manageable

AI summary
A method for displaying point-of-interest coordinate locations in perspective images and for coordinate-based information transfer between perspective images on different platforms includes providing a shared reference image of a region overlapping the field of view of the perspective view. The perspective view is then correlated with the shared reference image so as to generate a mapping between the two views. This mapping is then used to derive a location of a given coordinate from the shared reference image within the perspective view and the location is indicated in the context of the perspective view on a display.
