AI Technical Summary
Indoor positioning technologies face challenges in maintaining accuracy due to environmental changes and the need for frequent data updates, especially when infrastructure changes occur without altering the signal source's location, leading to degraded positioning performance.
A method that compares new opportunity signal data with previous data to detect differential values and classify the opportunity signal source, allowing for automatic detection of environmental changes and efficient handling of new data, ensuring accurate positioning without requiring manual updates.
This approach enables reliable and automated detection of infrastructure changes, maintaining positioning accuracy and reducing the need for frequent data updates, thus improving indoor positioning performance.
