Georeferenced AR Overlay for Realistic Military Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current training methods for emergency response and military maneuvers face challenges in achieving realism without the high effort and inflexibility of real environment simulations, and the artificiality of virtual simulations limits training effectiveness.
Innovation Solution
A method and system that superimpose virtual image content onto real image content using a georeferenced simulation environment, allowing for dynamic and realistic overlays by determining the user's position and viewing direction and accurately positioning virtual objects within a high-resolution, 2.5D or 3D simulation environment to create a realistic backdrop for virtual objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a realistic scenario is prepared and staged in a real-world training environment using training vehicles, actors, or similar props, then the degree of realism is improved, but the effort and cost required to prepare and execute the scenario increases significantly
Solution Approach 1:
The patent creates a digital copy (simulation environment) of the real training environment, including terrain, objects, and scenarios. This digital replica allows trainees to practice in a realistic setting without the logistical burden of physically staging the entire scenario with real vehicles, actors, and props. The simulation environment is georeferenced to match the actual location, providing visual correspondence while eliminating the need for physical setup.
2Adaptability or versatility
If a simulation environment is used to train personnel, then the variability and flexibility of training scenarios is improved, but the degree of realism and authenticity of the training experience deteriorates
Solution Approach 1:
The patent merges the advantages of both real-world training and simulation by combining a digital simulation environment with the actual physical location. The simulation is georeferenced to the real-world coordinates, and the display device shows virtual objects overlaid on the real environment as seen through the camera. This fusion allows the training to be conducted in the actual location (maintaining realism) while using digital elements (providing flexibility and variability).
Solution Approach 2:
The display device acts as an intermediary between the trainee and the training environment. It captures the real-world view through a camera and superimposes virtual elements onto this real-world image, creating a composite view that maintains the authenticity of the physical environment while adding the flexibility of programmable virtual scenarios. This intermediary approach allows the trainee to experience both realism and scenario variability simultaneously.
3Reliability
If live ammunition, aircraft, or artillery units are used in military exercises, then the realism and effectiveness of training is improved, but the complexity, cost, and logistical requirements of preparation and execution increase dramatically
Solution Approach 1:
The patent creates digital copies of military equipment (vehicles, aircraft, artillery) and places them in the simulation environment. These virtual representations can be configured and controlled through software, eliminating the need to physically deploy actual military hardware for training purposes. The digital models can be easily modified, repositioned, and controlled without the logistical burden of real equipment.
4Adaptability or versatility
If a simulation environment is used for training, then modifications and flexibility of scenarios are improved, but the static and inflexible nature of prepared scenarios in real environments becomes a limitation
Solution Approach 1:
The patent implements a dynamic training system where scenarios can be modified in real-time through software control. The simulation environment allows for dynamic adjustment of virtual objects, their positions, behaviors, and interactions without requiring physical reconfiguration. The system can adapt scenarios on-the-fly based on training objectives, making the training flexible and responsive to changing requirements.
