Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aerial vehicle navigation systems lack intuitive and real-time visualization of flight routes, making it difficult for pilots to detect hazards and navigate safely, especially in urban environments with low flight altitudes, and there is a need for user-friendly navigation and route guidance in bad weather conditions.
Innovation Solution
A method and apparatus providing augmented reality (AR) guidance for aerial vehicles, which includes acquiring flight images, generating AR route guidance objects, and displaying them in real-time, with features such as slope correction, hazard detection, and risk level indication, to help pilots navigate safely and avoid deviations from designated routes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional multi-function display is used to provide route guidance, then route information can be displayed numerically or in radar form, but the information is not intuitive and only experienced pilots can acquire it effectively
Solution Approach 1:
The patent transitions from conventional 2D radar displays to a stereoscopic 3D map display that provides intuitive spatial representation of flight routes and surrounding environment. This dimensional enhancement allows pilots to visually perceive route information and hazards more naturally, eliminating the need for specialized interpretation skills while maintaining comprehensive situational awareness
Solution Approach 2:
The system creates a virtual copy of the real-world environment through stereoscopic 3D map visualization, overlaying flight route information onto a realistic geographic representation. This virtual copy enables pilots to perceive route deviations and hazards in an intuitive format that mirrors actual spatial relationships, improving both usability and hazard detection
2Device complexity
If pilot only confirms front view, then simple navigation is possible, but dangerous objects on rear surface or side surface cannot be detected
Solution Approach 1:
The stereoscopic 3D map display system serves multiple functions simultaneously: it shows the flight route, displays surrounding terrain and buildings, indicates dangerous objects from all directions, and provides spatial orientation. This multi-functional visualization replaces the need for separate instruments while enhancing comprehensive situational awareness including rear and side hazard detection
Solution Approach 2:
The system introduces a virtual reality intermediary layer that consolidates information from multiple sensors and sources into a unified 3D visualization. This intermediary representation mediates between the complex multi-directional sensor data and the pilot's perception, enabling intuitive understanding of hazards from all directions without requiring the pilot to actively scan multiple instruments
3Device complexity
If conventional 2D display is used, then device complexity is low, but route visualization is not intuitive and route deviation cannot be detected in real time
Solution Approach 1:
The system employs stereoscopic 3D visualization to represent flight routes and terrain in true spatial relationships, allowing pilots to immediately perceive route deviations as visual separations between the aircraft icon and the designated route path. This dimensional enhancement eliminates the cognitive processing time required to interpret 2D radar coordinates while maintaining manageable system complexity through software-based rendering
Solution Approach 2:
The stereoscopic 3D display provides continuous real-time feedback by dynamically updating the aircraft position relative to the flight route as the aircraft moves. This immediate visual feedback mechanism allows pilots to detect and correct route deviations instantly, with the system automatically refreshing the visualization to reflect current spatial relationships between the aircraft, route, and terrain
