Solution Overview

Problem

Current 2D and 3D map technologies have limited texture resolution and geometry quality, and fail to provide optimal views of building models, especially when integrating street-level imagery into a full 3D scene, leading to disorienting transitions between aerial-derived 3D datasets and static panoramic street-level imagery.

Innovation Solution

A system and method for generating and navigating optimal views of 3D building models, which includes a view processing system that calculates and displays unobstructed or partially unobstructed views of building facades using a networked electronic device, employing machine learning algorithms to identify architectural features and rank views, and pre-calculating optimal views for navigation within a 3D map system.

Engineering Contradictions & Design Principles

1Manufacturing precision

If traditional 2D maps or basic 3D maps with aerial imagery are used, then the system is simple to implement, but the texture resolution and geometry quality are limited

Engineering Contradiction:
Improvetexture resolution and geometry qualityVSAvoidsystem complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent merges aerial-derived 3D datasets with street-level panoramic imagery to create a unified 3D scene. This combination allows the system to leverage the geometric accuracy of aerial data while incorporating the high-resolution textures and detailed views from street-level cameras, thereby improving both texture resolution and geometry quality simultaneously.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system pre-calculates and stores optimal views of building facades before user interaction. By performing view calculations in advance and caching the results, the system reduces real-time processing requirements, making the complex high-quality rendering operations feasible without requiring excessive computational resources during actual use.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If static panoramic street-level imagery is integrated into 3D scenes, then higher quality building views are achieved, but disorienting transitions occur between aerial and street-level imagery

Engineering Contradiction:
Improvebuilding model view qualityVSAvoiduser orientation and navigation
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The patent implements dynamic view transitions that adapt to the user's current position and orientation in the 3D scene. Rather than using fixed static transitions, the system continuously adjusts the transition parameters based on the user's movement, maintaining spatial consistency and preventing disorientation. This dynamic approach allows seamless blending between aerial and street-level views while preserving the user's sense of direction.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system introduces an intermediary transition mechanism that smoothly bridges aerial-derived 3D datasets and street-level panoramic imagery. This intermediary layer handles the transformation and blending between different data sources, ensuring that transitions are visually coherent and maintain spatial relationships, thereby preventing user disorientation during view switches.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If traditional 3D navigation methods are used, then comprehensive exploration is possible, but the navigation complexity increases significantly

Engineering Contradiction:
Improvenavigation simplicityVSAvoidnavigation system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts and highlights only the most relevant building facades and views based on the user's context and objectives. Rather than requiring users to navigate through all possible views, the system identifies and presents the optimal subset of views, simplifying navigation while maintaining comprehensive exploration capabilities. This extraction approach reduces the effective navigation space without losing important information.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system automatically calculates and presents optimal building facade views without requiring manual navigation adjustments from users. The view processing system autonomously determines the best perspectives based on building geometry, user position, and contextual information, thereby simplifying the user experience while maintaining comprehensive exploration capabilities through automated view selection.

Inventive Principle:
Principle #25Self-service
