GIS Scene Reconstruction via Embedded Metadata
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Geographic Information Systems (GIS) applications lack the ability to efficiently save and reconstruct scenes, limiting user experience and functionality in navigating and sharing spatial information.
Innovation Solution
A computer-implemented method and system that generates image data with metadata from a GIS application, allowing users to save and reconstruct scenes by including GPS data, camera position, and other relevant metadata, enabling seamless navigation and image retrieval across devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If GIS applications save only image data without metadata, then file size is reduced, but the ability to reconstruct scenes is lost
Solution Approach 1:
The patent extracts only the essential metadata elements needed for scene reconstruction (GPS coordinates, camera position, field of view, depth of field) from the complete scene data, embedding them in the image file. This selective extraction maintains scene reconstruction capability while minimizing data volume increase.
Solution Approach 2:
The patent performs preliminary encoding of metadata into the image file during the image saving process, so that when the image is later opened, the scene can be automatically reconstructed without requiring separate metadata files or manual input of scene parameters.
2Measurement precision
If GIS applications include comprehensive metadata in saved images, then scene reconstruction accuracy is improved, but processing time increases
Solution Approach 1:
The system extracts and embeds only the critical metadata parameters necessary for accurate scene reconstruction (GPS location, camera position, FOV, depth of field) rather than including all possible scene data, thereby maintaining reconstruction accuracy while minimizing processing overhead.
Solution Approach 2:
The patent changes the parameter representation by encoding metadata in a compact format within the image file structure, allowing rapid reading and processing of scene parameters without requiring extensive computational resources during image opening or sharing operations.
3Ease of operation
If GIS applications enable scene saving and reconstruction functionality, then user experience is improved, but application complexity increases
Solution Approach 1:
The patent implements self-service functionality where the image file automatically contains all necessary scene information through embedded metadata. When opened in the GIS application, the scene is automatically reconstructed without requiring user intervention to input scene parameters or configure settings, thereby improving ease of operation.
Solution Approach 2:
The patent merges the image data and scene metadata into a single integrated file structure, eliminating the need for separate scene configuration files or manual scene setup procedures. This consolidation simplifies the user workflow while managing application complexity through unified data handling.
4Adaptability or versatility
If GIS applications share scenes across devices, then collaboration capability is improved, but data transmission size increases
Solution Approach 1:
The patent extracts and embeds only the essential scene parameters (GPS coordinates, camera position, field of view, depth of field) into the image file, enabling cross-device sharing with minimal data transmission. The extracted metadata is sufficient for scene reconstruction without requiring transmission of complete scene datasets.
Solution Approach 2:
The patent creates a universal image format that embeds scene metadata in a standardized structure, allowing the same image file to be opened and scenes reconstructed across different devices and GIS applications without requiring device-specific data formats or additional configuration files.
