MOTION SENSOR FUSION IN INDOOR LOCALIZATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240357320 titled 'MOTION SENSOR FUSION IN INDOOR LOCALIZATION
Simplified Explanation: The patent application describes a method that combines wireless signal measurements and motion sensor measurements to estimate the location of an object, determine step presence, heading offset, step length, and heading.
- The method receives wireless signal measurements and motion sensor measurements.
- It generates a location estimate based on the wireless signal measurements.
- It determines step presence based on the motion sensor measurements.
- If a step is present, it calculates step heading offset, step length, and heading.
- The method then determines the location of the object based on either the wireless signal measurements or the step length and heading.
Key Features and Innovation:
- Integration of wireless signal measurements and motion sensor measurements for accurate location estimation.
- Determination of step presence and calculation of step parameters like heading offset, length, and heading.
