Stereoscopic 3D Radar Display for Air Traffic Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air traffic controllers face challenges in managing and visualizing air traffic data due to congested two-dimensional displays that require labor-intensive mental calculations for vertical separation and are fatiguing, with on-screen data clutter reducing situational awareness and increasing workload.
Innovation Solution
A method and apparatus for presenting air traffic data using stereoscopic displays that generate left and right eye images based on altitude disparities, providing an apparent three-dimensional separation of aircraft, allowing for improved visualization and management of air traffic data, including altitude, navigation cues, and airspace volumes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If two-dimensional radar displays are used to show air traffic data, then the display can show all aircraft positions and data, but the controller must perform constant mental calculations to determine vertical spacing and separation
Solution Approach 1:
The patent applies stereoscopic 3-D display technology to transform the traditional 2-D radar display into a three-dimensional visualization. This dimensionality change allows vertical separation information to be displayed directly in depth, eliminating the need for controllers to perform mental calculations. The left and right eye images with disparity values create a perception of vertical spacing, making altitude information immediately visible without cognitive processing.
2Quantity of substance
If traditional 2-D displays are used, then the system can display all aircraft data, but on-screen data clutter reduces situational awareness and increases workload
Solution Approach 1:
By transitioning from 2-D to 3-D display, the patent distributes aircraft data across three spatial dimensions. This allows multiple aircraft to be visualized simultaneously with their vertical positions clearly distinguished in depth, reducing screen clutter and improving situational awareness. The stereoscopic presentation organizes information spatially rather than relying on dense 2-D annotations.
3Measurement precision
If 3-D stereoscopic display is implemented, then vertical separation and spatial awareness are improved, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical 3-D display mechanisms with a software-based stereoscopic image generation system. The disparity values are calculated algorithmically from altitude data and applied to generate left and right eye images. This substitution of mechanical complexity with computational processing achieves 3-D visualization while maintaining system manageability.

AI summary
An apparatus and method of presenting air traffic data to an air traffic controller are provided. Air traffic data including a two dimensional spatial location and altitude for a plurality of aircraft is received. A disparity value is determined based on the altitude for each aircraft of the plurality of aircraft. Left and right eye images are generated of the plurality of aircraft where at least one of the left and right eye images is based on the determined disparity value. The left and right eye images are simultaneously displayed to the air traffic controller on a display. The simultaneously displayed images provide an apparent three-dimensional separation of each of the aircraft of the plurality of aircraft on the display.
