Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If synthetic vision systems use preloaded terrain databases, then the system structure is simple and easy to implement, but the terrain information becomes outdated and lacks real-time updates
Solution Approach 1:
The patent merges preloaded terrain database information with real-time sensor data to create an augmented synthetic vision system. The system combines static database information with dynamic sensor inputs, allowing updated terrain information to be overlaid on the existing synthetic vision display without completely replacing the database structure.
Solution Approach 2:
The system transitions from a static preloaded database to a dynamic augmented view by incorporating real-time sensor data. The augmented synthetic vision display dynamically updates terrain and obstacle information based on current sensor inputs while maintaining the underlying database structure.
2Loss of information
If multispectral sensors are integrated with synthetic vision database, then real-time terrain updates are achieved, but the image processing and data correlation become complex
Solution Approach 1:
The patent introduces an intermediary processing layer that correlates sensor data with the synthetic vision database. This intermediary system matches sensor-detected features with database information, automatically integrating real-time data without requiring complete system redesign.
Solution Approach 2:
The system creates a virtual copy of the terrain environment by rendering sensor data as visual representations that overlay the synthetic vision display. This copying approach allows real-time information integration while maintaining the structure of the original database.
3Measurement precision
If real-time sensor data is processed to create terrain mesh, then navigation accuracy is improved, but the computational load and processing time increase
Solution Approach 1:
The patent processes only the necessary portions of sensor data required for navigation and obstacle avoidance. Rather than processing all sensor information completely, the system focuses on extracting and rendering only the critical terrain features needed for safe operation.
Data Source
AI summary
A method for augmenting a synthetic vision system of a vehicle includes receiving, with a processor, signals indicative of real-time sensor data of a terrain for the vehicle via one or more acquisition devices; creating, with the processor, a terrain mesh of the terrain in response to the receiving of the sensor data; correlating, with the processor, the terrain mesh with preloaded terrain data of the terrain; creating, with the processor, a multispectral image of the terrain in response to the correlating the terrain mesh with the preloaded data; and texturing, with the processor, the terrain mesh for display on a display device.
