3D Geospatial Visualization with Indoor-Outdoor Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for three-dimensional visualization of geospatial data are limited by their two-dimensional origins, restricting viewer movement and experience to the vantage point of the source image, and are biased towards vehicular navigation rather than pedestrian or bicycle experiences, lacking unified indoor and outdoor representations.
Innovation Solution
A client-server system that utilizes GPS-coordinated 3D point cloud data to render geospatial models, allowing users to move freely and interact with both interior and exterior settings, including heat-maps and secret passages, with customizable experiences for pedestrians, bicyclists, and automobile users, and real-time event integration through video cameras.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional two-dimensional visualization methods are used, then the system complexity is low, but the viewer's freedom of movement and exploration is restricted
Solution Approach 1:
The patent transitions from two-dimensional panoramic images to three-dimensional point cloud representations, enabling viewers to move freely in 3D space rather than being constrained to fixed 2D viewing angles. This dimensional transformation allows exploration from multiple perspectives including interior and exterior views, directly resolving the contradiction between ease of operation (viewer freedom) and system complexity.
Solution Approach 2:
The system integrates multiple levels of detail and representations within the 3D point cloud structure, allowing nested viewing experiences from macro outdoor environments to micro interior spaces. This nesting approach enables comprehensive exploration freedom while managing complexity through hierarchical organization of spatial data.
2Adaptability or versatility
If conventional two-dimensional panoramic images are used, then the data processing requirement is low, but the unified indoor/outdoor representation is not achieved
Solution Approach 1:
The 3D point cloud representation serves multiple functions simultaneously: it provides both outdoor environmental visualization and indoor space representation, supports various user perspectives (pedestrian, vehicular, aerial), and enables diverse interaction modes. This universal representation approach achieves unified indoor/outdoor visualization while the system manages the increased data requirements through efficient processing architectures.
3Adaptability or versatility
If conventional automobile-oriented navigation is used, then the system design is simple, but the pedestrian and bicycle experiences are not accommodated
Solution Approach 1:
The system implements dynamic adaptation to different user types (pedestrians, bicyclists, vehicular users) by adjusting the 3D point cloud rendering parameters, movement constraints, and interaction modes based on the selected user persona. This dynamic configuration allows the same underlying 3D representation to serve multiple user experiences without requiring separate systems for each user type, balancing versatility with manageable complexity.

AI summary
Using various embodiments, methods, and systems for implementing three-dimensional geospatial visualization techniques are disclosed. In one embodiment, a unified indoor/outdoor three-dimensional visualization of interior and exterior settings can be provided using a publically accessible geospatial website. The geospatial website can provide global positioning system coordinated point cloud data of actual exterior settings along with fantasized or actual interior settings to a client machine along with information of events occurring at the location in real time.
