Oblique Image Selection in 3D Virtual Scenes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack an efficient method for automatically selecting and displaying geo-referenced oblique images within a 3D or 4D virtual scene, making it difficult for users to access and analyze large collections of oblique imagery.
Innovation Solution
A system comprising an oblique motion model, selection process, and display process that allows users to interactively navigate a 3D/4D virtual scene, automatically selecting and geo-registering the best-fit oblique image from a warehouse based on their viewpoint, and displaying it within the scene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually select oblique images from a large collection using thumbnail interfaces, then image selection capability is provided, but user interaction complexity and time consumption increase significantly
Solution Approach 1:
The system automatically selects and retrieves the appropriate oblique image based on the user's viewpoint within the 3D virtual scene, eliminating the need for manual thumbnail navigation. The image selection process is performed autonomously by the system, reducing user effort and time consumption while maintaining accurate image retrieval.
Solution Approach 2:
The patent replaces the mechanical interaction of manually clicking through thumbnails with an automated computational selection process. The system uses viewpoint data and image metadata to automatically determine and retrieve the appropriate image, substituting manual mechanical operations with automated algorithmic processing.
2Measurement precision
If oblique images are manually geo-registered in a 3D virtual scene, then image positioning accuracy is achieved, but the process complexity and time required increase
Solution Approach 1:
The system performs geo-registration automatically in advance based on pre-stored image metadata and viewpoint information. The appropriate oblique image is pre-selected and positioned in the 3D virtual scene before the user needs to view it, eliminating the need for manual geo-registration operations while maintaining positioning accuracy.
Solution Approach 2:
The geo-registration process is performed autonomously by the system using stored metadata about image locations and user viewpoint, eliminating manual intervention. The system self-performs the complex computational tasks of determining correct image positioning without user involvement.
3Adaptability or versatility
If a comprehensive collection of oblique images is stored and made accessible, then image coverage and analysis capability improve, but system complexity and data management burden increase
Solution Approach 1:
The system introduces an intermediary layer of metadata and automated selection logic between the user and the large image collection. This intermediary structure organizes the comprehensive image warehouse and enables automatic retrieval based on viewpoint, allowing extensive image coverage without proportionally increasing user-facing complexity.
Solution Approach 2:
Manual image management and selection operations are replaced with automated computational processes. The system uses algorithms to manage the comprehensive image collection and automatically retrieve appropriate images based on viewpoint data, substituting complex manual data management with automated system processing.
Data Source
AI summary
A system for selecting oblique images from a collection of geo-referenced oblique images and viewing them within the context of a virtual, three- or four-dimensional (3D space and time) geographic scene, providing the ability to analyze and interact with the oblique image being viewed. The system automatically selects and displays the best fit oblique image from an image warehouse based on the user's current 3D/4D viewpoint, and continuously maintains the geo-registration of the oblique image as the user adjusts the viewpoint.
