Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems struggle with efficiently visualizing and manipulating non-composite oblique imagery datasets due to scale variations and perspective distortions, and lack seamless integration with three-dimensional model data for synchronized viewing and interaction.
Innovation Solution
A system that maintains synchronized point of view (POV) between oblique imagery and three-dimensional model data by generating synchronized updated POV information based on user inputs, allowing simultaneous and seamless switching between different view modalities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If non-composite oblique imagery datasets are used for visualization, then more natural perspective and side-angle views of buildings and terrain features are achieved, but scale variations and perspective distortions occur
Solution Approach 1:
The patent introduces an intermediary coordinate transformation system that maps oblique imagery coordinates to a standardized reference coordinate system. This intermediary transformation layer resolves the scale variation problem by mathematically correcting perspective distortions while preserving the natural oblique perspective benefits, thereby eliminating the contradiction between ease of capture and scale precision.
Solution Approach 2:
The patent dynamically adjusts visualization parameters including scale factors, perspective angles, and coordinate transformations based on the specific oblique imagery characteristics. By changing these parameters adaptively, the system maintains scale consistency across different oblique images while preserving their natural perspective advantages, thus resolving the contradiction.
2Adaptability or versatility
If separate viewing systems are used for oblique imagery and three-dimensional model data, then independent optimization of each view type is achieved, but synchronized viewing and interaction between the two modalities is lacking
Solution Approach 1:
The patent merges the separate viewing systems for oblique imagery and 3D model data into a unified synchronized viewing system. This combination maintains the independent optimization capabilities of each view type while adding synchronization mechanisms that enable coordinated interaction, thereby resolving the contradiction between versatility and ease of synchronized operation.
Solution Approach 2:
The patent implements feedback mechanisms where user interactions with one view modality automatically update the other view modality. When users navigate, zoom, or rotate in either the oblique imagery view or the 3D model view, the system provides real-time feedback by synchronizing the corresponding transformations in the other view, thus enabling seamless synchronized interaction while preserving independent view optimization.
3Area of stationary object
If composite oblique imagery is used to cover larger areas, then broader geographic coverage is achieved, but increased complexity in image composition and alignment occurs
Solution Approach 1:
The patent segments the large geographic area into multiple manageable oblique imagery tiles or sections, each processed and aligned independently using standardized coordinate transformations. This segmentation approach enables broad geographic coverage while avoiding the complexity of composing and aligning large composite images, as each segment can be handled separately and then seamlessly assembled through coordinate system standardization.

AI summary
Described are systems and techniques for view synchronization between oblique aerial imagery and three-dimensional model data of a same geographic scene. Information corresponding to an updated point of view (POV) of a geographic scene displayed based on corresponding view information obtained for a first view type modality can be obtained. Updated POV viewpoint information of the first view type modality can be provided to a viewer engine for a second view type modality for the same geographic scene. The updated POV viewpoint information of the first view type modality can be used to generate a synchronized updated POV viewpoint information of the second view type modality. The updated view of the geographic scene can be output for display using the updated POV viewpoint information of the first view type modality. The synchronized updated POV viewpoint information of the second view type modality can be output for display.
