2D 3D Scene Correlation via Synchronized Cursors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft vision systems face challenges in correlating two-dimensional (2D) and three-dimensional (3D) views of geographical regions, leading to difficulties in identifying and localizing objects or regions of interest due to differences in view scale, angle, and depth cues, which hinders navigation and decision-making processes.
Innovation Solution
A system that includes a processor and display device on an aircraft, capable of correlating 2D and 3D views by identifying image points in one view and determining corresponding geographical locations, positioning cursors or indicators in both views to synchronize visual content, using geographical data from multiple sources such as cameras and databases.

Engineering Contradiction Analysis
1Measurement precision
If 2D and 3D views are displayed separately, then each view can be optimized for its specific purpose, but it becomes difficult to correlate and locate objects between the two views
Solution Approach 1:
The patent introduces cursor indicators as intermediary elements that appear in both 2D and 3D views to establish correspondence between them. When a user selects an object in one view, a cursor appears in both views pointing to the corresponding object, enabling accurate localization without requiring complex automated correlation systems.
Solution Approach 2:
The cursor indicator serves multiple functions: it acts as a selection marker in the active view, a correspondence indicator linking to the other view, and a localization tool for identifying objects in both 2D and 3D representations. This multi-functionality simplifies the overall system while improving localization accuracy.
2Productivity
If automated correlation between 2D and 3D views is implemented, then object identification is improved, but the system complexity increases
Solution Approach 1:
The system enables users to manually control the correlation process by selecting objects in one view, which automatically triggers the cursor to appear in both views. This user-initiated approach eliminates the need for complex automated correlation algorithms while maintaining high productivity in object identification.
Solution Approach 2:
The system prepares both 2D and 3D views with corresponding cursor indicators in advance, so that when a user selects an object in one view, the corresponding cursor is already positioned in both views. This preliminary preparation eliminates the need for real-time complex processing during object identification.
Data Source
AI summary
Systems and methods for correlating visual content in 2D and 3D scenes of a geographical region can include at least one data source for providing geographical data, a display device of an aircraft, and a processor. The display device can display a 2D view and a 3D view representing top-down views of the geographical region using data received from the data source(s). The processor(s) can identify a first image point within the 2D view referenced by a first cursor of the 2D view. The processor(s) can determine, using information received from the at least one data source, a geographical location corresponding to the first image point. The processor(s) can determine a second image point within the 3D view corresponding to the determined geographical location. The processor(s) can position a second visual indicator of the 3D view to reference the determined second image point within the 3D view.
