Positioning Environment Modeling With Simulated Measurement Training

The patent creates virtual copies of physical environments through 3D modeling and digital twins. These virtual environment models replicate real-world positioning scenarios, allowing the system to generate synthetic training data that mirrors actual measurement conditions without requiring physical access to diverse locations. This copying approach enables comprehensive environmental coverage while maintaining data authenticity.

The system performs preliminary actions by pre-collecting environment information and pre-generating synthetic positioning measurements for various scenarios before actual positioning needs arise. This advance preparation creates a library of training data covering diverse environments, so when positioning is needed in any environment, the model is already trained and ready, eliminating the need for on-site data collection.

Instead of physically accessing inaccessible areas to collect measurements, the system creates virtual copies of these environments using available information such as building plans, maps, or partial measurements. The synthetic data generation process replicates positioning measurements as if they were taken in the actual inaccessible environment, bypassing the need for physical access while maintaining training quality.

The patent introduces an intermediary synthetic data generation process that bridges the gap between accessible and inaccessible areas. This intermediary layer uses environment information and simulation algorithms to translate available data into comprehensive training datasets, mediating between what can be easily measured and what is needed for robust model training.

The system performs preliminary calibration by generating synthetic measurements using simulated positioning signals that are pre-configured to match real signal characteristics. Environment information such as building geometry, material properties, and antenna configurations are incorporated into the simulation to ensure synthetic measurements accurately reflect real-world physics and measurement conditions before actual positioning operations begin.

The patent implements feedback mechanisms where synthetic measurements are continuously refined based on comparison with available real measurements. The system uses measured data to validate and adjust simulation parameters, creating a feedback loop that progressively improves measurement precision. This feedback ensures synthetic data maintains high accuracy while preserving the efficiency benefits of generation.
